80-50 Scratch / Dig Optical Bandpass Filters

Bandpass Interference Filters
from CeNing Optics Co., Ltd.

Band pass filter plates are divided into short-pass and long-pass filters according to whether they transmit below or above the transition wavelength. The transition wavelength or cut-on/off wavelength is the wavelength at which the transmission is 50% of its peak value. [See More]
