China Bk7 K9 Uvfs Right Prism Dove Prism Corner Cube Prism Wedge Prism

There are many types of prism, each having a particular geometry to achieve the reflections necessary to perform a specific imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam. Dispersing prisms produce spectral separation for spectroscopic.

Qinhuangdao Intrinsic Crystal Technology Co., Ltd provides many kinds of high precision prisms, including Penta Prism, Beamsplitter Penta Prism, Dove Prism Right Angle Prism, and Corner Cube Prism,etc.

Right Angle Prism: are precision polished to light tolerances for more demanding applications. They are available in either BK7 or UV Fused Silica. BK7prisms are recommended for general laboratory use in the visible and near IR. For UV, infraved, or thermally sensitive applications Fused Silica prisms are advised. Our Fused Silica prisms are manufactured to exacting specifications and are useful from 0.16-2.10μm.

Right angle prism is deviating or deflecting a beam of light with 90° or 180°.It is often used in telescope, periscope and other optical system.

Dove Prism: has two applications. The main application is used as a rotator. It can rotate an image but without deviating the beam. And when the prism is rotated about the input parallel ray through some angle, the image rotates through twice that angle. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it perform as a right-angle prism.

Corner Cube Prism: It has three mutually perpendicular surfaces and a hypotenuse face. Light entering through the hypotenuse is reflected by each of the three surfaces in turn and will emerge through the hypotenuse face parallel to the entering beam regardless of the orientation of the incident beam. For its special performance, it is often used to the distance measurement, optical signal process and laser interferometer.

Wedge Prisms have similar function with optical windows. They all can be used as isolating components. Wedges may be used to produce a small deviation, which don't allow return to the source.
