Buyers Guide | Green Laser Safety Glasses

Published by The Laser Safety Experts | Laser Safety Industries | Minneapolis, MN on Dec 9th 2020

Green laser safety glasses typically refer to laser safety eyewear that pertains to lasers falling in the range of 575nm - 495nm.

Green Laser Safety Glasses Spectrum

Green lasers are some of the most dangerous as our eyes are the most sensitive to green. It should be noted, two lasers with the same name "Copper Vapor" may be lasers with different wavelengths - always refer to the wavelength and not the name of the laser (although it is often specified in conjunction with the laser).

For our entire selection of laser safety glasses, click here. Below we will discuss the trade-offs specifically regarding our "green" laser safety glasses and goggles we thought you might find helpful.  Here are a few common green lasers: 

532nm laser
Double YAG laser (532nm)
Argon laser
KTP laser

For general trade-offs among polycarbonate, glass, and dielectric coated laser safety glasses, please refer to our general guide of How to Choose Laser Safety Glasses here.  For convenience, we've included the graphic below explaining the optical density notation with our products:

Please note, some assumptions have been made - the photons depicted are not drawn to scale, and finally please be sure to reach out if there is any uncertainty.  Be sure to ask your laser safety officer ("LSO") or feel free to give us a call with any questions or clarification that may be needed.

Here is a chart of the the different laser safety eyewear (by SKU), against the Optical Density protection for our green laser safety glasses.

The 110 filter is our most selling product. It has an OD of 6+ from 190-532nm while are the same time still having a high visible light transmission ("VLT"). This can be particularly useful if working in dark environments. The 130 can be preferable if this is not a concern or you're looking for more protection and less VLT. The glass options can also work well depending on the wavelength.  Below the dielectric coated options are discussed below:

Filter 325 

Optical Density:
OD 6+ @ 532 nm
Visible Light Transmission:

45%
Material:
Dielectric Coated
SKU #: 100-xx-325

If your entity is looking at protection from multiple laser safety wavelengths, or is trying to avoid compromising VLT for protection, the dielectric coated glasses may be your best option. The drawback is price. Generally, we can find a more economical solution than our coated glasses. If you have questions, please give us a call, we'd love to discuss options.
