Roof Prism

This Roof Prism is used when a right angle deflection of an image or laser beam is required. In passing through the prism, the image is both deflected right-left and top-to-bottom. The hypotenuse of the prism utilizes TIR (total internal reflection) to reflect the image through the prism.

Dove Prism

The dove prism is used as an image rotator. The output image created by the dove prism rotates at twice the angular rate of the prism rotation.

Round Wedge Prisms

Wedge Prisms are used primarily in laser beam steering applications. A beam normal to the perpendicular surface of the prism is deflected through the angular deviation listed By combining two prisms that can be rotated independently, it is possible to direct the beam anywhere within the cone angle defined as 4 times the angular deviation of a single wedge.

Equilateral Dispersion Prism

Dispersion Prism create less stray light and eliminate the higher order problems associated with diffraction gratings. Dipersion prisms are often used as an initial dispersion element in an optical system.

Pellin Broca Prism

Pellin Broca Prisms can be used to separate the harmonics of a laser beam or compensate for group velocity dispersion. The light enters and exits the crystal near Brewster's angle, which minimizes reflection before exiting the crystal. The angle between the input and exit beams is 90deg. plus a small angle due to dispersion. The dispersion is less for longer wavelengths.

Micro-Prisms

In traditional optics, many kind of prisms are designed for image reversion or deflection purpose. As laser and CCD are widely used in advanced imaging, less and less prisms are need for the design of imaging optical system. However, in some case prism still plays an important role.

OptoCity design and make special micro-prisms to meet the requirement of advanced optics. Please contact OptoCity's engineer about your request.
