◆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. |
