FB820-10 Dia:1 in Bandpass Filter; CWL=820 +-2nm; FWHM=10 +-2nm

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.

The filter is available from Thorlabs' website, and the link provided indicates that it is currently in stock. This information, along with the detailed specifications, should assist users in their search for optical components with similar properties.
