Band Pass Filter
A band-pass filter is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. It uses a special optical material substrate that solves the problems of fogging and unstable optical performance of conventional absorptive synthetic glass. On the basis of outstanding narrow-band filter characteristics, its optical performance is not affected by the thickness of the substrate, making it easier to establish an instrumental imaging system. The optical performance has been improved and effectively applied.
China Star Optics can provide different types of custom optical filters are available, such as optical comb filters, optical high pass filters, optical low pass filters, colored glass filters, colored glass filters, crystal optical filters and linear variable filters.
