FBH810-10 Premium Bandpass Filter; Dia:25 mm; CWL=810nm; FWHM=10nm

The FBH810-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter is specifically designed for use in applications where a narrow band of light needs to be isolated from a broader spectrum.

The filter has a circular shape with a diameter of 25 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems. It is constructed from UVFS material, identified by the Mal-1965 material ID, ensuring durability and stability under various environmental conditions.

The FBH810-10 Filter is centered at a wavelength of 810 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light transmission in a narrow band around 810 nm, while effectively blocking light outside this range. The cut-on wavelength is 805 nm, and the cut-off wavelength is 815 nm, further illustrating its narrowband transmission characteristics.

The filter features thin lens shape, which can be beneficial in certain optical system configurations. Both the front and back surfaces of the filter are coated with the THo FBH810-10 coating, providing optimal performance and protection.
