Acrylic Longpass Filters are frequently used for lens protection and economical enclosure windows, as well as over light sources to control the wavelength emission of broad-spectrum light sources. Because of their durability, they’re commonly used in Food & Drug Administration (FDA) and European Food Safety Authority (EFSA) regulated applications where glass over the inspection area is prohibited. AC370 and AC380 offer anti-abrasion, anti-reflection coating, which can also withstand harsh solvents such as alcohol, acetone, or MEK.
