FBH660-10 Premium Bandpass Filter; Dia:25 mm; CWL=660nm; FWHM=10nm

The FBH660-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter is circular in shape with a diameter of 25 mm and a thickness of 2 mm, making it suitable for a wide range of optical applications.

The filter is specifically designed for a central wavelength (CWL) of 660 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light within a narrow band around 660 nm to pass through while blocking out other wavelengths. The cut-on wavelength is 655 nm, and the cut-off wavelength is 665 nm, further enhancing its wavelength selectivity.

The FBH660-10 filter features a thin lens shape and is made from UVFS material, identified as MAL-1965 in the catalog. The front and back surfaces of the filter are coated with Thorlabs' proprietary coating, denoted as "tho fbh660-10", which enhances its performance and durability.
