High Transmittance 490nm Long Wave Pass Filter
Long-wave pass filter is a kind of filter that effectively transmits light beams in a certain wavelength range. Long-wave pass filter cuts off light shorter than center wavelength, while short-wave pass filter is just the opposite.
Long-wave pass filter and short-wave pass filters, as important optical components, are characterized by allowing light in one wavelength band to pass through while allowing light in another wavelength band to cut off.
It is mainly applied to medical dedection instruments, beauty photon machines, multi-band criminal detection instruments, stage lighting systems, iris recognition and digital image applications.
