FB440-10 Dia:1 in Bandpass Filter; CWL=440 +-2nm; FWHM=10 +-2nm

The FB440-10 is a Bandpass Filter from Thorlabs, designed with a circular base shape and made from soda lime ru clear material. This filter is part of Thorlabs' extensive catalog, which includes a wide variety of optical elements from different vendors worldwide. The FB440-10 is specifically designed for use in systems where precise wavelength selection is required.

The filter has a center wavelength (CWL) of 440 nm, with a full width at half maximum (FWHM) of 10 nm, providing a narrow band of wavelengths for transmission. The cut-on wavelength is 435 nm, and the cut-off wavelength is 445 nm, ensuring a high level of rejection for wavelengths outside this range.

The FB440-10 has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it compatible with many optical systems.
