850FH90-50S 50x50mm Standard Long Wave Pass Edge Filter, Cut-on 850nm
The 850FH90-50S is a Longpass Filter from Andover Corporation, designed with a standard rectangular shape and thin lens characteristics. This filter is made of fused sil mal-1965, a high-quality material known for its durability and optical clarity.
The filter has a width and height of 50mm each, with a thickness of 3mm, making it a compact yet robust optical component. It is specifically designed for long-wave pass applications, with a cut-on wavelength of 850nm. This means it allows light with wavelengths longer than 850nm to pass through while blocking shorter wavelengths.
The coating on both the front and back surfaces of the filter is 'and 850fh90', which is presumably a proprietary coating developed by Andover Corporation for optimal long-wave pass performance.
