FB550-40 Dia:1 in Bandpass Filter; CWL=550 +-8nm; FWHM=40 +-8nm
The FB550-40 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 primary function is to allow light within a specific range of wavelengths to pass through while blocking other wavelengths.
The FB550-40 is designed to pass wavelengths around 550 nm, with a Full Width at Half Maximum (FWHM) of 40 nm, indicating a narrow band of wavelengths that can pass through. The filter's cut-on wavelength is 530 nm, and the cut-off wavelength is 570 nm, further defining the range of wavelengths it allows.
This filter features a thin lens shape and is coated on both the front and back with the same coating, "tho fb550-40". According to the vendor's information, the filter is currently in stock and can be purchased directly from Thorlabs' website.
