What is a Triple Bandpass Filter?
A triple bandpass filter is an optical filter designed to transmit three selected wavelength bands while reducing transmission outside these bands. It combines multiple transmission windows within a single optical filter and is suitable for systems that require selective multi-band light transmission.
