All 40m safety glasses are absorbent.

 

They were scanned by 180 mW  2mm spot size  of 1064 nm beam and  their  transmissions were measured

They showed no degradation.

 

UVEX 's  LOTG-YAG/CO2 glasses (fits over personal glasses) 11 pieces,

Glendale-XC by Bacou-Dalloz,  #1166218VLT68% , aerodynamic style, 7 pieces, (4 missing )

Atm.2  showing our muilty wavelength glasses of 1064 and 530 nm

Their transmittance for both wavelength were zero.

 

Note: if you have prescripton safety glasses I would like to scan it for you !
