YAG Double Harmonics Laser Safety Glasses – Model 33 Fitover

The YAG Double Harmonics (YAGD) Model 33 is a laser safety fitover built for people who already wear prescription spectacles. A brown polycarbonate YAGD filter is cut and mounted into the Phillips Safety Model 33 frame, so you can keep your own glasses on underneath and still have filtered protection across the front and sides.

The YAGD filter covers two bands that matter in Nd:YAG work: the visible and UV range up to 534 nm, and the near-infrared band around 1064 nm. Phillips Safety lists the filter as CE certified to EN 207, with EN 207 markings published for each band. Visible light transmission is around 26%, so the view is noticeably darker than clear lenses.
