Beamsplitter Cube provide easy alignment and form no ghost images. These beamsplitters come with either metal or dielectric coating. Tian Cheng optics can supply narrowband and broadband wavelength beamsplitter cube. It is widely used in projection optics systems, imaging optics systems, optical measurement systems & optical display systems.

An Interference Filter reflects one or more spectral bands or lines and transmits others, while maintaining a nearly zero coefficient of absorption for all wavelengths of interest. It consists of multiple thin layers of dielectric material having different refractive indices. There also may be metallic layers.

Neutral Density Filter reduces the brightness of an image without changing the color of the scene. It allows all wavelengths to pass through equally. Neutral density filters are categorized by their optical density (D) which is defined as the logarithm to the base 10 of the reciprocal of the transmittance (T): T=10-D

It''s fabricated by special color glass material. Color Glass Filters are designed by their manufacturers to transmit and / or absorb different wavelengths of light. Tian Cheng optics can supply a full range of filter. They are short pass, long pass, band pass, ultraviolet, infrared, heat absorbing, and color temperature conversion filters. We use material by China to Schott, Hoya, and other manufacturers to process them. Metallic films, colored glasses and thin dielectric films filter are all a
