Titanium Doped Sapphire Crystal (Ti:Sapphire)

Geodetic Surveying series

The actual reflecting surface of Metal Coated Mirror is usually a thin coating of silver , gold or aluminum on glass.

Dielectric HR Mirror offers near total reflection, minimizing losses in nearly all optical systems. It has a high reflectivity in a narrow band or broadband wavelength.

Low(multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applicatios where the increased sensitivities are not an important.

Due to the rotation activity of natural quartz crystal, it also can be used as polarization rotators so that the plane of input linearly polarized beam will be rotated at special angle which is determined by the thickness of quartz crystal.

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

This type of zero order waveplate is designed for high damage threshold applocation (more than 1GW/cm2).

By adding a wedge, it can be used as Precision Penta Prism. It is often used in plumb level, surveying, alignment, range finding and optical tooling.

Wedge Prism is an optical element having plane-inclined surface, usually the faces are inclined toward one another at very small angles. Wedge Prisms divert light toward their thicker portions.
