Follow all safety and operating instructions. It is never advisable to look directly into laser beams. The responsibility and liability for injuries due to the use of unsuitable means of protection and improper use lies with the customer. LASER SAFETY EYEWEAR SELECTION GUIDE LASER SPECIFICATIONS Consult your laser’s manufacturer’s guide for eyewear requirements. Calculate optical density (OD) and power density requirements based on wavelength, power in watts (or for pulsed systems, using wavelength, power in joules, pulse length in seconds and pulse repetition rate in hertz). OD is the attenuation or reduction of energy transmitted through the lens. The higher the OD value is, the higher the attenuation and the greater the protection level. OD is directly related to wavelength since it measures the ratio of light absorbed to a specific wavelength. NOTE: Are there engineering controls limiting exposure to the beam? Is partial beam visibility required for alignment of visible beams? Is protection required for intra-beam exposure or is protection primarily for diffuse or scattered energy? For medical applications, are there different eyewear considerations for the Clinician and patient (in terms of VLT-visible light transmittance, full orbital coverage, weight of eyewear)? Will filter color / color rendition affect use? Are there multiple laser systems in the area, or is the eyewear designated for a single system? DAMAGE THRESHOLD, AND VISIBLE LIGHT TRANSMITTANCE (VLT) REQUIREMENTS Make sure the filter will reduce possible energy exposure to below the Maximum Permissible Exposure (MPE). Check the Photopic Visible Light Transmittance (VLT) of the filter. VLT is the percentage of visible light (380 to 720 nm) transmitted through a filter or lens, calculated against the spectral sensitivity of the eye to daylight. The higher the better. VLTs below 20% should be used in well-illuminated working environments. Consider Absorptive or Interference filters-Absorptive filters may be polymer + dye based or glass, and function by absorbing laser energy. Interference filters employ thin layers of reflective material for protection. Hybrids combine both technologies. Lightweight polymer filters offer varying VLTs and mid-level damage thresholds for UV, Visible and near IR, with lower damage thresholds for IR. Polymer filters are cost effective, easy to wear and offer the highest impact resistance, while heavier glass filters can offer higher VLTs and higher damage thresholds at higher expense, and dielectrically coated and hybrids offer the highest VLTs, highest damage thresholds (in that some energy is not absorbed but reflected), at the highest cost. ADDITIONAL CONSIDERATIONS Eye protection can only be effective when worn. Laser safety eyewear is of no use if it is sitting on the shelf. If eye protection is too heavy, poorly fitted, poorly designed or the VLT is too low, users will make the wrong choice: not to wear it. Always wear laser eye protection when operating or when around lasers. You only get two eyes.

FREQUENTLY ASKED QUESTIONS QUESTIONS SOLUTIONS How do I clean my laser safety eyewear? Use the following cleaning methods for WEI Laser Safety Eyewear:

Mild detergent/soap and hot water
Diluted isopropyl alcohol solutions (70-85% max)
Commercially available lens cleaning solutions
UV disinfection
Clean eyewear with clear water and neutral cleaning agents and dry gently with a soft cloth. Improper cleaning can damage the lens surface and/or compromise the integrity of the lens or frame.
Do not use caustic chemicals or acidic cleaning fluids
Do not insert into sterilization or disinfectant fluids
Do not clean with ultrasonic systems
Polycarbonate and glass lenses are mounted into nylon or polycarbonate frames. Filter absorption and protection properties are molded into the lenses and won’t fade, scratch, bleach or wear off. However, discard and replace eyewear if surface scratches impair vision or if the eyewear is broken, cracked or otherwise cosmetically compromised. Do these filters have an expiration date? The official expiration date is 5 years, however, the protection provided by the filter is molded into the lens and does not decrease if the eyewear is well preserved, unscratched, and properly cared for. The protection does not degrade, scratch off or photobleach. Eyewear that show any damage to the filter or frame, or discoloration should be replaced. If you have any concerns, please contact us with your questions. What impact standards do these safety glasses meet? All eyewear in this datasheet meet the ANSI Z87.1 impact standard and the increased robustness per the CE EN207 specification. How do I know what filter to select? When given a selection of filters that fit the specified wavelengths and OD for your application, choose the one with the highest VLT. If you are unsure and need assistance, please contact our sales department for help in determining the most appropriate filter choice. Can I see the laser beam with laser safety eyewear? For laser safety eyewear with EN207 certification, the specified wavelength or wavelength ranges are absorbed or reflected, and the beam spot of a visible laser radiation is not visible. For laser safety eyewear with EN208 certification, the laser beam of the speficied wavelength or wavelength ranges is attenuated to a safe level while still allowing some visiblity for alignment. For full protection eyewear, if the beam is still visible, this would mean that the protection level of the eyewear is not high enough, or that secondary radiation (at a different wavelength) is generated. Always confirm the marking of the laser safety eyewear matches the requirements of the laser. The protection of carefully selected eyewear will remain stable when hit by the laser throughout a minimum period of 5 seconds 50 pulses under standardized conditions. Nevertheless, it is under no circumstances advisable to look into the beam directly. How do I align my visible laser? You should never put down your laser safety eyewear when working with lasers above class II. Use certified beam display devices to locate and help align beams. Alignment filters do not absorb or reflect the laser radiation completely. The radiation is often only reduced to values below 1mW for continuous wave lasers (see laser class 2). Do not exceed the power (R – protection level) given on the eyewear with the average power of the laser. Can I purchase laser safety eyewear with a different color filter? The color is determined by the requirements for particular wavelengths or ranges at specific optical densities and there may not be a choice of different colors for a given set of parameters. Often, though, there will be a selection of several options and the decision which filter to use should then take into consideration the VLT and color recognition. © 2024 www.teamWavelength.com 23 LASER SAFETY EYEWEAR
