Our products green color filter glass LB1-4 are equivalent to bandpass filters VG/VB series of Germany Schott and Green Filters G Series of Japan Hoya.
Green color long pass filter glass transmit a relatively narrow wavelength band centered around light in the green spectrum. They are used as contrast-effect filters for black and white photography, and also as 3-color separation filters. Bond these filters and sharp cut filters together to attain the maximum transmittance at a specific wavelength or to absorb light of shorter wavelengths.
Main Application: Camera Lens, Display Equipment, Stage Lighting Device, Fluorescent Spectroscopy Systems.
