FB680-10 Dia:1 in Bandpass Filter; CWL=680 +-2nm; FWHM=10 +-2nm
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.
According to the vendor's information, this item is in stock and available for immediate purchase. The filter's catalog number is FB680-10, and it can be found on Thorlabs' official website.
