Infrared Filter Acrylic Sheet

Infrared Filter Acrylic Sheet is a specialized optical material designed to selectively transmit or block infrared radiation while maintaining visible light properties as needed. Constructed from high-purity PMMA resin with added infrared-absorbing dyes or coatings, this advanced material offers precise spectral control across near-infrared (NIR) and mid-infrared (MIR) wavelengths. Available in various configurations including long-pass, short-pass, and band-pass filters, it provides exceptional optical clarity combined with the mechanical benefits of acrylic—10 times the impact resistance of glass and half the weight.
