20mm Square IR Cut-Off Filter

Product Details 710nm Cut-Off Wavelength Circular and Rectangular Options Various Sizes Available IR Cut-Off Filters are ideal for eliminating illumination beyond the visible spectrum in many visual and detector-based applications. These filters feature a 710nm cut-off wavelength. IR Cut-Off Filters are traditionally coated and have a BOROFLOAT substrate. BOROFLOAT is about three times more resistant to thermal shock than standard soda lime glass. IR Cut-Off Filters are available in circular and rectangular versions with various sizes for each.
