FB390-10 Dia:1 in Bandpass Filter; CWL=390 +-2nm; FWHM=10 +-2nm
The FB390-10 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 out other wavelengths.
The FB390-10 is designed to pass light with a central wavelength (CWL) of 390 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows a range of wavelengths around 390 nm to pass through, with the intensity of the transmission being half of its maximum at 385 nm and 395 nm, the cut-on and cut-off wavelengths respectively.
The filter's coating, applied to both the front and back surfaces, is designated as 'tho fb390-10'. This coating plays a crucial role in the filter's performance, ensuring the specified wavelength range is transmitted while other wavelengths are blocked.
