The MF390-18 is a Bandpass Filter from Thorlabs, designed with a circular base shape and a diameter of 25 mm. This filter is made from UVFS material, specifically identified as MAL-1965, and has a thickness of 5 mm. The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths.
The MF390-18 is designed to pass light with a central wavelength (CWL) of 390 nm and a bandwidth (BW) of 18 nm. This means it will allow light between 381 nm and 399 nm to pass through, making it ideal for applications that require the use of specific wavelengths. The filter's cut-on wavelength is 381 nm, and the cut-off wavelength is 399 nm.
The filter's coating is consistent on both the front and back surfaces, featuring the coating 'tho mf390-18'. This coating enhances the filter's performance and durability. The filter's shape is that of a thin lens, which can be beneficial in certain optical system configurations.
