Corner Cube Prisms/ Corner Cube Retroreflectors
Feature:
Incident light deviates by **0 deg independently of the angle of
incidence
Applications:
Plumb Level, Surveying, Alignment, Range finding, Laser range
finder, Optical Tooling, Distance finding, Distance measurement,
Optical signal dispose, Optical signal process, Laser
interferometer, Fire detector, etc..
Description:
BK7 or UVFS Corner cube retroreflectors are designed to deviate
incident light by **0 degrees independent of the angle of
incidence. These prisms have 3 mirror surfaces making angles of *0
degrees to each other, juxtaposed to form the corner of a cube with
the entrance face perpendicular to cube diagonal. All beams,
independent of the direction of incidence, are reflected back.
Corner cubes are used for high precision applications or with
lasers working in very long distances.
The corner cube can reflect the incident light back its original
source. It is used in length measurement system as its reflector.
It has been designed for measuring the distance between the moon
and the earth, when Apollo spaceship reached the moon, corner cube
was set on the surface of the moon for scientific research use.
Retroreflection Prisms are used in applications where precision
alignment is difficult or tedious. Retroflection Prisms reflect
incident light back to the light source no matter the orientation
of the Retroreflection Prism. Unlike an Optical Mirror, which needs
to be at the normal angle of incidence in order to reflect light
back to the source, a Retroreflection Prism can be oriented in any
position so long as the light is hitting the entrance face. A
Retroreflection Prism utilizes several total internal reflections
to enable it to operate at even the most extreme angles of
incidence.
