Optical Filter

Ruike Optics manufacture narrow bandpass filter, Long pass filter, short pass filter, Dichroic filter.

Narrow band interference filter is a kind of optical component with a very narrow half-bandwidth, which can allow a certain band of light to pass through, and allow other bands of light to cut off (or high inverse), without interference from other light.

Our company's interference filter adopts medium hard film, ion assisted deposition technology, evaporates in high vacuum, the film layer is firm and high, good density, imaging clear
