Prism Type Material Illustration Applications
Penta Prism BK7 Penta prism can deviate an incident beam
without inverting or reversing to 90°. The
deviation angle of 90°is independent of any
rotation of the prism about an axis parallel to
the line of intersection of the two reflecting
faces. It is commonly used in Plumb Level,
Surveying, Alignment, Rangefinding and Optical
Tooling.
Please refer to this page for more information
about Penta Prisms.
Beamsplitter
Penta Prism
BK7 By adding a wedge and with partial refractive
coating on surfaces S1, it can be used as a
beamsplitter. It is often used in Plumb Level,
Surveying, Alignment, Rangefinding and Optical
Tooling.
Please refer to this page for more information
about Beamsplitter Penta Prisms.
Right Angle Prisms BK7
Fused Silica
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.
Please refer to this page for more information
about Right Angle Prisms.
Dove Prism BK7 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. Another application is used as
a retroreflector. For this application it perform
as a right-angle prism.
Please refer to this page for more information
about Dove Prisms.
Roof Prism BK7 Roof prism is combined with a right angle prism
and a totally internally reflecting roof and they
are attached by them largest square surfaces.
It can invert and reverse an image, also, deflect
the image 90° . Therefore, it is often used in
terrestrial telescopes, viewing systems and
rangefinders.
Please refer to this page for more information
about Roof Prisms.
Corner Cube
Retroflector
BK7 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 the incident beam.
For its special performance, it is often used to
the distance measurement, optical signal
process and laser interferometer.
Please refer to this page for more information
about Corner Cube Retroflector.
Anamorphic Prism SF11 These two prisms can expand or contract the
beam in one direction without any changes in
the other direction. By adjusting the angles
among the incident beam and two prisms, the
shape of the beam can be changed. It is very
easy to turn elliptical bean into circular beam.
Dispersing prisms BK7
Fused Silica
SF-14
Dispersing prisms are used for wavelength
separation applications. A light ray is twice
refracted through the prism with a total
deviation of qd. Deviation is a function of
refractive index, and hence wavelength.
Wedge Prism BK7
Fused Silica
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.

about Wedge Prisms.
