Protect Lenses from Impurities
Protective filters protect lenses from dirt, dust, harsh ambient conditions and so on. Usually, they block a portion of the UV spectrum, although those used in infrared applications block visible wavelengths too.
Protective filters from Polytec come in glass or acrylic.
