  Right-angle Prisms

Right angle prisms are typically used to bend image paths or for redirecting light at 90°. Using the features of critical angle, effectively total internal reflection of incident light is one of the basic functions of right angle prisms. Right angle prisms are easy to install and have better stability and strength to the mechanical stress, so they are the ideal optical parts for all kinds of devices and instruments.

  ◆Roof Prisms

Roof prisms can both revert and invert the image as well as bend optical fiber at 90°. With the features of smaller size, roof prisms can make the objective lens and eyepieces lens in a line, which are suitable for compact binoculars, telescopic systems, etc.

  ◆Powell Prisms

Powell prisms as a line generator, can be used to display a uniform straight reference line for use in alignment, machine vision systems, construction and process control. In addition, the lenses may also be used on lower power lasers, lenses are available in fan angles of  5°, 7°, 10°, 30°, 45°, 60°, 75°, 90° and 100°  for custom applications. All the wavelengths with line generating lens are available.

Product Application: Telescopic system, imaging system and range-measurement system
Material: K9, fused silica
CNI can offer different kinds of roof prisms upon your requests.
