FB750-40 Dia:1 in Bandpass Filter; CWL=750 +-8nm; FWHM=40 +-8nm
The FB750-40 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 in a specific wavelength range to pass through while blocking other wavelengths.
The FB750-40 is designed to pass light in the wavelength range of 750 nm, with a Full Width at Half Maximum (FWHM) of 40 nm. The FWHM is a measure of the filter's bandwidth, indicating the range of wavelengths that the filter allows to pass. The Cut-On wavelength is 730 nm, and the Cut-Off wavelength is 770 nm, defining the edges of the passband.
The filter's coating, applied to both the front and back surfaces, is designated as 'tho fb750-40'. This coating enhances the filter's performance, ensuring efficient light transmission within the specified wavelength range. The filter's shape is that of a Thin Lens, which may contribute to its optical performance in certain applications.
According to the vendor's information, the FB750-40 is in stock and available for immediate purchase. The catalog number for this item is FB750-40, and it can be found on Thorlabs' official website.
