FGL850S 2 in x 2 in Square RG850 Colored Glass Filter; 850nm Longpass
The FGL850S is a 2 in x 2 in Square RG850 Colored Glass Filter, specifically designed for longpass applications at 850nm. This filter is sourced from the renowned optical component manufacturer, Thorlabs.
The filter is a color glass type, characterized by its rectangular base shape and thin lens form factor. It is made from the high-quality N-BK7 Schott material, ensuring durability and reliability. The filter's dimensions are 50.8mm in width and height, with a thickness of 2mm, making it suitable for a wide range of optical applications.
The FGL850S features a physical data specification of a cut-on wavelength at 850nm and a cut-off wavelength of 0nm. This longpass characteristic allows for the efficient transmission of longer wavelengths while effectively blocking shorter wavelengths.
The filter's coating is another notable feature. Both the front and back surfaces are coated with the THo FGL850 coating, enhancing its performance and longevity.
