These lenses have positive focus length. Most suitable where one conjugate is more than five times, the other. e.g. in sensor application or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.

Achromatic doublet lenses have significantly better optical performance than singlet lenses in visible imaging and laser beam manipulation applications. Achromatic Lenses are consist of two elements, usually of a positive low-index crown glass cemented to a negative high-index flint glass that have been corrected for chromatic aberration with respect to two or more selected wavelengths. We provide achromatic lenses consisting of two elements. These lenses have considerably reduced not only chrom

Glass aspheric lens is also called condenser lens, mainly applicable for stage lighting, optical lighting system, etc. We bring in hot briquetting technology from Japan, with volume production ability, including aspheric lens which surface form error is within 100 micron.

Cylindrical lens is used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images. Especially widely used to anamorphic compression of LD (laser diode) output beam.

Rod Lens is designed for use in a variety of laser and imaging applications. The addition of this product line is part of a continued effort to support current trends toward miniaturization.

Spherical ball lenses are widely used in optical measurement systems, projection & imaging optical systems. Also for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling.

Right Angle Prism may be used as a 90 degree reflector or 180 degree retroreflector. The prism deflect, deviate and rotate beams of light as well as dispersing their wavelengths. They usually used for beam deviation or as substrates for beamsplitters.

Corner Cube Prism is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.

Window are of high precision dimension control, minimal transmitted beam deviation, high surface quality. With those excellent features, the BK7 ,Sapphire,Infrared etc window is widely use in projection optics systems, imaging and optical measurement system.

Tian Cheng optics can supply long-wave pass filter, short wave pass filter, wide band pass filter, narrow band pass filter, super narrow band pass filter and high reflection filter etc. It covers 1um to 40 um.

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.

A plate type (mirror-type) beamsplitter is an optical window with semi-transparent mirrored coating to break a beam into two or more separate beams. A beamsplitter will reflect a portion of the incident energy ( see reflection %), absorb a relatively small portion, and transmit the remaining energy (see transmission %). Beamsplitter plates have very neutral color characteristics and are often referred to as beam-splitters plate.
