FBH650-10 Premium Bandpass Filter; Dia:25 mm; CWL=650nm; FWHM=10nm

The FBH650-10 Premium Bandpass Filter is a high-quality optical component designed and manufactured by Thorlabs. This filter is specifically engineered to allow light transmission within a narrow band of wavelengths, making it an ideal choice for applications that require precise wavelength selection.

The filter has a circular shape with a diameter of 25 mm, ensuring a wide area of light transmission. It boasts a thickness of 2 mm, providing robustness and stability during integration into optical systems. The FBH650-10 is part of the UVFS MAL-1965 material family, which guarantees consistent performance and compatibility with other components in the same series.

The FBH650-10's primary function is to transmit light at a center wavelength (CWL) of 650 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light transmission between 645 nm and 655 nm, effectively filtering out light outside this range. The 'cut on' wavelength is 645 nm, and the 'cut off' wavelength is 655 nm, further illustrating the filter's precise wavelength selection capabilities.

The filter's front and back surfaces are coated with the THo FBH650-10 coating, enhancing its performance and durability. The coating ensures high transmission efficiency, low auto-absorption, and excellent environmental stability. The filter's shape is described as 'Thin Lens', indicating its potential use in applications where a lens-like component is required.
