Optical Corner Cube Prism and Retroreflectors for Range Finding

Short Description:

Corner cube prisms are prisms which act as corner reflectors, a type of retroreflectors. The basic operation principle is that there are internal reflections on three mutually orthogonal prism surfaces, leading to a direction of a reflected beam which is nominally parallel to the direction of the incident beam – with the accuracy limited only by the accuracy of the surface orientation of the prism. Precision prisms can offer excellent parallelism of incoming and reflecting beams. It is usually specified as an angular deviation, e.g. < 2 arcseconds.

Product Detail

Product Tags

Despite the name containing the term “cube”, corner cube prisms are generally not having the geometric form of a cube. Instead, the input/output side is oriented roughly perpendicular to the direction of incoming beams, and opposite to it there is the “corner” formed by three mutually perpendicular surfaces. The exact orientation of the input/output surface is not critical, but it is easier to have an effective anti-reflection coating when the incidence is roughly perpendicular. Usually, the input/output surface is equipped with a broadband AR coating. Imperfect operation of the coating leads to a parasitic reflected beam.

Corner cube prisms may be supplied as bare prisms, or together with holds for mounting e.g. to a surface. They are often used in the context of optical metrology, e.g. in interferometers, and in spectroscopy.

A corner cube, also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam’s angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.

Yasi can offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements. Custom laser-line and broadband anti-reflection coatings are available on the entry faces; and protected aluminum, silver, or gold coatings are available on the reflecting faces to enhance total internal reflection

Product Parameter

Designed for the surveying of high-precision project, it is compatible with various total stations to carry out high-precision surveying, and is widely used in high-precision surveying and mapping for high-speed railway and other field. In conjunction with the total station, orientation and ranging can be carried out. The operational principle is that the total station sends out a laser beam. After calculating the reflection time of corner cube prism, the distance from the total station to corner cube prism can be calculated according to the speed of light. Then the total station can calculate the coordinates of the prism according to the coordinates of the rear view.
