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.
An optical glass filter is an optical device used to select the desired wavelength of radiation. A common feature of filters is that no filter can make the image of a celestial object brighter, because all filters absorb certain wavelengths, thus making the object darker. Its main feature is that the size can be made quite large. Thin-film filters generally transmit longer wavelengths and are mostly used as infrared filters.
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.
