The FB820-10 is a Bandpass Filter from Thorlabs, designed with a circular base shape and a diameter of 1 inch (25.4 mm). This filter is made of soda lime ru clear material and has a thickness of 3.5 mm. The filter's coating, both on the front and back, is tho fb820-10.
The FB820-10 is designed to transmit light in the center wavelength (CWL) range of 820 nm, with a full width at half maximum (FWHM) of 10 nm. The cut-on wavelength is 815 nm, and the cut-off wavelength is 825 nm. This specificity in wavelength transmission makes it ideal for applications that require precise light filtering.
