The 550FH90-50S 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, making it a square shape, and a thickness of 3.3mm. It is specifically designed with a cut-on wavelength of 550nm, meaning it starts to transmit light at this wavelength and beyond. The cut-off wavelength is 0nm, indicating that it allows all wavelengths shorter than the cut-on to pass through.
The coating on both the front and back surfaces of the filter is 'and 550fh90'. This coating is likely designed to enhance the filter's performance and durability. The filter is currently in stock and available for purchase through the Andover Corporation's website.
