The FB680-10 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 primary function is to allow light within a specific range of wavelengths to pass through while blocking other wavelengths.
The FB680-10 is designed to pass light in the wavelength range of 680 nm, with a Full Width Half Maximum (FWHM) of 10 nm, indicating a narrow band of wavelengths that can pass through. The Cut-On wavelength is 675 nm, and the Cut-Off wavelength is 685 nm, further defining the range of wavelengths this filter allows.
The filter's coating, applied to both the front and back, is 'tho fb680-10'. This coating enhances the filter's performance and durability. The filter's shape is that of a Thin Lens, suggesting it may have applications where light focusing is required.
