A filter that transmits a relatively narrow band of wavelengths centered around the green wavelength range.
The "green filter" is a filter that transmits a relatively narrow band of wavelengths centered around the green wavelength range. It is named after the wavelength at which its transmittance is at its highest. If you want to achieve maximum transmittance at a specific wavelength or absorb wavelengths below a certain point, this can be accomplished by bonding these filters with sharp cut filters. It is used as a contrast effect filter in black and white photography, as well as a green filter for tricolor decomposition. 【Features】 ■ Transmits a relatively narrow band of wavelengths ■ Used as a contrast effect filter in black and white photography ■ No angle dependence due to the angle of incidence ■ No change in transmittance/absorption wavelength characteristics ■ Can be cut to any size through post-processing, even with relatively large glass substrates *For more details, please refer to the PDF document or feel free to contact us.
