Hello, I wish to know which product would be most suited for a class 4 laser (blue, 445nm, 1W total optical output) such that its possible to view the laser safely. Yu-Hung Lai In January 2016, lasers were again in the headlines as another new iteration of this threat presented itself. Victor Ma If one component of the LB-Rating is shared, a plus sign is used to separate multiple wavelength ranges or laser modes and scale numbers in order to save space. The interior is 145mm x 53mm and have a 140mm temple. Regards, I will reach out to you directly about your custom needs. Plus, independent research has shown that many, if not the majority, of commercially available laser pointers are incorrectly classified, with power output exceeding designated compliance levels set by the Code of Federal Regulations[x]. For more information on ANSI, see here. A response from Tyler at Thorlabs to reza1729: I will email you a more detailed response but here is a summary. We may be able to offer a custom version that may cover all of your wavelengths. If you refer to the OD Specs chart, you will see that the optical density of all of the LG glasses falls in the 5 to 7 OD value in the 190 to ~400 nm range. Anti-laser glasses will reduce visible light transmittance, so the view may be dimmer. We need to see enough to manipulate the samples under the lights and look at a computer screen. I was thinking LG2 but its level of protection does not seem sufficient. Hundreds of thousands of Revisions laser protective lenses have been sold all over the world over the last 10 years, including to the U.S. Army, U.K. MoD, Dutch DMO, Belgium MoD, the Canadian DND, Greek MoD, Swedish MoD, the German MoD, and the South African Air Force. Counter-optical lasers used in demonstrations have gained notoriety due to a number of high-profile incidentsSeattle, WA, for one, saw protesters at a WTO summit direct pointers in the field of vision of crowd-control police; and in Genoa, Italy, gatherers enacted an operation to utilize 1,000 mirrors to reflect laser light back at troops[i]. Please see specifications for additional information about the frame and the filter, or contact us. 1) The recommended storage temperature is for long term storage of laser glasses that are not being used.

Teledyne wins $7.7 million contract for 3,137 ALEP Block 2 spectacles. Assuming you are working with a 2mm beam diameter at 100mW, 473nm and 593nm, both CW, these fall under the same calculation class. Visible light transmission is 57%. A severe burn of the cornea may produce a loss of vision even after healing. Keep in mind that this is assuming a focused or collimated laser; however, if we factor in the divergence from the tip of the fiber, the actual incident light onto the glasses will be much less. As the optical part is still ok, I would lik to buy a few frames without optics, so I can repair my sticky ones, which nobody wants to use anymore. We will consider adding such a feature on the website. Determine the power density, wavelength and mode you will be working with. Response from Chris at Thorlabs: Thank you for using our feedback tool. We recommend selecting the highest possible optical density (OD) for the wavelengths you need to block.

Lasers have been used en masse against riot police in demonstrations in regions as diverse as Canada, the U.S., Ireland, Thailand, Greece, Egypt, and Italy, among others. the frame of our LG11A broke - is it possible to get a new frame/replace it ourself? The color and transmitted light may vary from what is shown. Hello, i would appreciate some advice on laser safety goggles. The expected cost was $125 per pair, for 1,000 pairs of glasses. Best, Pilots who want to use LGP can do so -- subject of course to any rules applied by their airline or employer. Response from Jeremy at Thorlabs: We will look into carrying this as a regular stock item. BALPA (British Airline Pilots Association), for one, has found that half of all pilots experienced a laser attack in the past 12 months. 20% of proceeds from every LE Edition purchase will be donated to Concerns of Police Survivors (C.O.P.S.). Green multiplex lasers as well as high-powered green laser pointers operate at or close enough to this wavelength that Argon laser safety glasses are essentially laser safety glasses for laser pointers as well. 2) The L-ratings for each pair of laser glasses are listed on the web page and on the spec sheet. Refer to the, The OD and LB-Rating Specifications are determined by the filters in the glasses, NoIR model # DI4. All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use. Dear Support, You can see the OD as a function of wavelength for each type of google on our website. One of the members of our technical support staff will be contacting to you so we can make a goggle suggestion based on your application. The LB-Rating is composed of 3 components: a wavelength range, a laser mode designation, and a scale number. Numerous worldwide aviation officials and organizations, as well as federal agencies, have expressed heightened awareness and urgency on this front[v]. Hi, Best, Thanks. Hi Thorlabs, it would be nice to have a tool where I plug in my laser parameters and it suggests the correct glasses. In case we havent give the requested document to our Customs office we wouldnt get The frame design of other Thorlabs glasses does not have such problems; as far as I can tell LG11 is the only different frame model. My question is about if these model, LG16C, is suitable for working with a 40 W Class IV CO2 Laser engraver, which wavelength is 10640 nm. We will look into improving the frame design to be more in line with the standard universal frames. Argon laser safety glasses can help. We do not recommend any highly caustic solutions. Actual photo of Airbus A330 banking while coming in to land at Zurich airport. We used them occasionally and they were mostly kept in their cases. And the threat is not confined to the US, with incidents reportedly on the rise in many countries throughout the world. The Stingerhawk FT-2 Laser Protective Eyewear provide the needed protection for the laser wavelength of concern, the feature wrap around protection and ballistic protection required for law enforcement operations. Are you doing custom glasses for supercontinuum use. Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. The warranty information can be found on the product page (https://www.thorlabs.com/thorproduct.cfm?partnumber=LG11A). Fourth, what sort damage should I keep an eye for on the goggle? We may be able to provide a custom goggle. But, much more powerful handheld lasers are available and are technically legal as long as they are not advertised for pointing or beam-display purposes. The right type of goggles would depend highly on the environmental condition (i.e. Do you sell detachable inserts for prescription lenses separately? Universal StyleUniversal Style laser safety glasses feature a large (145 mm x 53 mm) frame that can be worn comfortably on top of prescription glasses. Our laser glasses selection and the OD specs of each of our models can be found on the product family page here: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=762. which goggles would you recommend for 100mW (0.7mm diameter) 405nm laser alignment? Eye injuries may occur if you directly view the beam, especially when using optical instruments. for customs office. while working near the beam path. Hi, Class 4: I don't wear prescription glasses, but do require reading glasses (that can be purchased for about $5 a pair from Amazon). So if the LG3 glasses are being used with a 10 s pulsed 280 nm light source the table above can be referenced to find that, E=3x10n+1 J/m2, where in this example the scale number is LB4 so n=4. As for the dual-use question, it would be difficult to provide general information that would be beneficial to a wide group since the correct saftety goggles are highly application specific. 2. wavelength Range (nm) 630-655, THORLABS Range/optical Density(OD) 625 to 850 nm OD= 4+, Typical Wavelength = 650 nm. For your second comment, we had a graphical chart in our most recent catalog that I believe would aid in the selection process. Increasingly, for protestors and rioters, lasers offer superior standoff capabilities against police forces, resulting in officer vision disruption, distraction, disorientation, and even incapacitation. Response from Buki at Thorlabs: Thank you. Seeing the increase in malicious use of green lasers to distract or blind law enforcement and military personnel, Revisions team wanted to make sure that the company offered the most protective and functional eyewear available to those forces[xiv]. ", Hello, These Laser goggles have been designed to reduce the amount of incident light of Green or violet Laser to safe levels, while transmitting sufficient light for good vision, These safety goggles will protect your eye from excessive 532nm green laser beams. Cracked lenses or frames also warrant replacement of the glasses. Revision is committed to providing a full complement of high-impact, laser protective solutions for military, tactical, law enforcement, and aviation use in a wide variety of hostile conditions.

Hello. I have reached out to you directly to clarify the specifics of your experience! LSOs (Laser Safety Officer) need to consider working environments, viewing conditions and beam delivery systems when making assessments and determining the correct laser glasses , goggles, barriers, or windows to protect against potentially hazardous laser radiation. These laser safety eyewear are made with polycarbonate lenses that protect against Green laser 200 to 532nm and infrared radiations of 900 to 1100nm. The information from each graph is corroborated by the specifications table next to the graph. The scale number (LBn) is intended to be used in conjunction with the wavelength range and the laser mode designation in order to determine if the laser safety glasses meets the minimum required level of protection for a given laser; see the table below. Correspondingly, laser threats are a particularly difficult danger to get a handle on because the threat is often hidden. In other words, if you purchase a pair with VLT of 12%, you might want to take them off before going down stairs and such because you will not be able to see well. THORLABS Range/optical Density(OD) 190 to 534 nm OD= 7+, Typical Wavelength = 532 nm. The "b" refers to the footnote "b" right below the spec table: "For the M rating of LB7 in the wavelength range of >950 to 1064 nm, the glasses were tested at pulses between 12 ps and 170 fs. 4. wavelength Range (nm) 750-1000, THORLABS Range/optical Density(OD) >740 to 1070 nm OD= 7+, Typical Wavelength = 760 -930 nm. Please email techsupport@thorlabs.com if you are interested in a custom option. Although we can try to obtain this data for you, that wavelength is outside the specified range. Energy per pulse: 30 mJ Do not use Laser Viewing Cards in place of a proper, The OD and LB-Rating Specifications are determined by the filters in the glasses, NoIR model # YG3. Thank you for your interest in our products. Would the LG2(19%VLT) be suitable for the task or would you rather advice the LG11 (75%VLT) or another type? eric. Thanks. The LG4 goggles are ANSI Z136 compliant. we need CE sertification sheet of LG10 - Laser Safety Glasses For a 1W laser, we highly recommend you discuss your laser safety requirements with your laser safety officer to ensure you purchase the appropriate goggles.

California Institute of Technology, Response from Jeremy at Thorlabs: The LG11 lens is more difficult to cut than the other ones and they are not available in the universal style. I am interested in glasses that have OD 3+ at 780nm and OD 7+ at 1550nm. The diagonal of the lenses is 68mm. Provide approx. We recommend selecting the highest possible optical density (OD) for the wavelengths you need to block. Filter specifications are permanently engraved. However, if the beam is refocused, the hazard may be increased and the class may be changed accordingly. The function that defines the visible light transmission is weighted by the sensitivity of the human eye which is governed by ANSI and EU standards. 750-800 +> 1100-1120 DIR LB6 +M LB6Y Our group would like to purchase your LG11 product. I need glasses that will be appropriate for use with both Ti:sapphire and Insight lasers with wavelengths of 680-1300 nm. Hi Albert, thank you for contacting Thorlabs. Dear Sir/Lady Even relatively cheap, easily obtainable lasers can have operating ranges up to a few kilometers at night, and often emit as much as 50 to 1,000 mW of power, a factor of 10 to 200 times higher than the MPE of a safe pointer[xiii]. Do not operate lasers without correct protective equipment and training. GF-8 laser lenses allow greater VLT and color recognition, are treated with Revisions OcuMax Plus anti-fog coating, provide 100% UV-A-B-C protection, and are made from high-impact polycarbonate that exceeds military ballistic impact requirements. What is OD at 455 nm? Hello, thank you for contacting Thorlabs. Thanks in advance! From the abstract: It describes design criteria used in the development of laser protective devices, operational considerations, training, fit, inspection, maintenance and immediate response procedures to follow after suspected laser exposure. Lasers are categorized into different classes according to their ability to cause eye and other damage. Lasers of this class must be equipped with a key switch and a safety interlock; moreover, laser safety signs should be used, such that the laser cannot be used without the safety light turning on.
