FBH780-10 Premium Bandpass Filter; Dia:25 mm; CWL=780nm; FWHM=10nm

The FBH780-10 Premium Bandpass Filter is a high-quality optical component designed for precise wavelength selection, manufactured by Thorlabs. This filter is specifically engineered for use in applications where a narrow band of wavelengths 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 designed to have a central wavelength (CWL) of 780 nm, which is the wavelength at which the filter has its maximum transmittance. The full width at half maximum (FWHM) of this filter is 10 nm, indicating that it allows wavelengths within a 10 nm range around the CWL to pass through while significantly attenuating wavelengths outside this range.

The FBH780-10 filter is made from UVFS, a material with a high refractive index and low absorption, ensuring high transmission and excellent optical quality. The filter is coated on both sides with a special coating, denoted as 'tho fbh780-10', which enhances its performance by reducing reflection and increasing transmission.
