Maximum Contrast for Viewing Fluorescent Indications
The BlueLine filter glasses are designed to work with the BlueLine lights to provide maximum contrast for seeing fluorescent indications. The glasses block all of the blue light that is reflected from the inspection surface and transmits only the fluorescence from the indication.
You cannot use just any yellow glasses (shooting glasses, blueblocks, etc.) with the BlueLine lights. The BlueLine filter glasses are specially designed to work together with the BlueLine lights for maximum rejection of reflected light to give you maximum viewing contrast. Use only filter glasses marked with the BlueLine NDT name.
All BlueLine filter glasses conform to ANSI Z87.1 impact standards for safety glasses.
