FBH520-10 Premium Bandpass Filter; Dia:25 mm; CWL=520nm; FWHM=10nm

The FBH520-10 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 compatible with a wide range of optical systems.

The filter is specifically designed for a central wavelength (CWL) of 520 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 a narrow band of wavelengths around the CWL to pass through while blocking out other wavelengths. This makes it ideal for applications that require high wavelength specificity, such as fluorescence microscopy or laser spectroscopy.

The FBH520-10 filter is made from UVFS material with the catalog number MAL-1965. The front and back surfaces of the filter are coated with the same coating, denoted as 'tho fbh520-10', which enhances its performance and durability. The physical data of the filter indicates that it is cut on at 515 nm and cut off at 525 nm, further emphasizing its narrow bandpass characteristics.
