FB450-40 Dia:1 in Bandpass Filter; CWL=450 +-2nm; FWHM=40 +-8nm

The FB450-40 is a Bandpass Filter, part of the extensive catalog of optical elements offered by Thorlabs. This particular model is designed with a circular base shape, made from soda lime ru clear material. The filter has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it compatible with a wide range of optical systems.

The FB450-40 operates at a central wavelength (CWL) of 450 nm, with a full width at half maximum (FWHM) of 40 nm, providing a narrow bandwidth for precise optical filtering. The filter's cut-on wavelength is 430 nm, and the cut-off wavelength is 470 nm, ensuring efficient blocking of unwanted wavelengths.

The filter's coating, applied to both the front and back surfaces, is designated as 'tho fb450-40'. This coating enhances the filter's performance, contributing to its high-quality optical characteristics. The filter's shape is that of a Thin Lens, further expanding its potential applications in various optical setups.
