Bandpass filter / Band Pass Filter
Bandpass filters (also called band pass filters, BP filters or band-pass filters) have been a mainstay of Giai's business since 2008. They are designed to have high transmission over a certain wavelength range while blocking light from other wavelengths to provide good signal-to-noise in the transmitting region.
Peak Transmission is the maximum transmission of the filter (%).
Center Wavelength (CWL) is the midpoint of the transmitting region (nm).
Full-width half-max (FWHM) describes the width of the transmitting region at half of the maximum transmission value (nm). Because of the physics of thin-film interference filters, FWHM generally increases with wavelength. It can be calculated using a percentage of the center wavelength
