A filter that transmits a specific wavelength at green from blue, and cuts off other wavelengths in the visible range. It is used to select blue or green wavelength from a light emission or select a specific wavelength from multi-wavelengths.

◦A selection of different type of main wavelength and bandwidth from 370nm to 550nm.
◦To select a wavelength from a large bandwidth light.
◦By insertion of the filter into microscope or CCD camera will provide better contrast in a vision experiment.

Guide

▶We are also providing bandpass filter with narrow wavelength (model VPF).
W3119
▶We can provide high transmittance filter for interference application (model YIF).
W3118
▶We also can supply to custom specifications which are not mentioned on-line or in our catalog, please contact our Sales Division with your request.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶The absorption wavelength range can not be used with high power laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter and there is a transmission loss of about 10%.
▶Due to the specifications of the glass material of the green filter, you can not obtain a high and sharp transmittance, we recommend using the high transmittance interference filter (model YIF).
