Right Angle Prism

 Right angle prisms turn light through 90° by internal reflection from the hypotenuse, or 180° from two right angle surfaces. When the light incident angle is perpendicular to the right angle surfaces, the light will be reflected at the surface of glass/air interface.

 

When the input light is incident from hypotenuse surface, the light will be fully reflected in the glass / air interface at the right angle surfaces. The second total reflection occurs at next right angle surface.

 

Compared to regular reflective mirrors, right angle prism are easily to be mounted; further its reliable mechanical stress has better stability and strength. Hence right angle prism have been considered as suitable alternatives to reflective mirrors in various applications.

 

Hyperion Optics supplies a range of right angle prisms to meet UV-Visible-NIR applications, with high surface quality and tight tolerance angles.  Our materials selection ranges from BK7, Bak4, fused silica, ZnSe, CaF2 etc.

 

Material tips for your application:

For working wavelength down to 175nm or so, with low thermal expansion requirement, Fused silica is the right choice with tighter tolerance control due to its excellent mechanical stability.

For visible and NIR wavelength, N-BK7 or CDGM H-K9L is suitable and cost effective.

For infrared wavelength, ZnSe and germanium are the right material to pick up.

Calcium fluoride has relatively wide transmittance range from 0.18~8um, it is the best choice when your application covers such wide transmission range.

 

Hyperion Optics has full capability of processing right angle prisms based on the materials we proposed above with 3 precision levels fit your actual demand.

Penta Prism

 Penta Prism are used to define right angles in optical systems. Penta Prisms, which provide right handed images, feature a ray deviation of 90°. Penta Prisms are five-sided prisms and unaffected by slight movements. Edmund Optics offers a variety of Penta Prisms for optimal performance in the Ultraviolet (UV), Visible, or Infrared (IR) spectrums.

 

The pentaprism will neither invert nor reverse the image. Penta prisms are extremely useful in alignment systems as they define a right angle very precisely and independently of angle of incidence. Rays entering one face emerge from the adjacent face at precisely 90 deg after they have undergone two reflections inside the prism for a total of 270 deg. The penta prism acts as a turning mirror which is insensitive to alignment.

 

optical glass prism is often used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling

Dove Prism

 Dove prism are used as reflective prism inverting the image. Dove prism is shaped from a truncated right-angle prism. Normally, dove prisms are used in the parallel optical path based on critical angle principle to meet total internal reflection with limited FOV.

 

A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image is inverted but not laterally transposed.

 

A beam of light entering the sloped faces undergoes total internal reflection from the bottom surface, and emerges from the opposite sloped face. Also interestingly whtn dove prisms optical are rotated along longitudinal axis, the image rotates at twice the rate of the prism which have applications in fields such as interferometry, astronomy, and pattern recognition. Dove prisms can be also used as right angle prisms with sloped faces HR coated.

Corner Cube Retroreflectors

 Corner cube is total reflecting prism formed by 3 perpendicular surfaces, where the incident light angle does not influence the final emerging light angle but reflected by 180°, it offers excellent parallelism between the incident and exit beams.

 

Hyperion Optics supplies both corner cube prism in mount or without mount, our precision corner cube retroreflectors have been used for Laser ranging, positioning and guidance, laser communication, optical transformation.

 

Our typical production accuracy is beam deviation < 5 arc sec in diameter within 2 inches. Please see our precision and tolerance grid for your information.
