Corner Cube Prism
Corner Cube Retro Reflector are used to reflect light beam back to the direction that it comes from. The reflected beam is always parallel to to the incident beam, and it travels in the reverse direction of the incident beam. This hold true regardless of the angle of incident beam.
The beam reflection is achieved either through total internal reflection or by mirror coating on the rear surface of the retro reflector . An Incident beam filling the effective aperture, is reflected exactly back on itself.
The Protective Al2 coating can be given to the rear reflecting Surface to avoid total internal reflection failure at high incident Angle.

Dove Prism
Lens: Dove Prism
Application: These Lenses Have Considerably Reduced Values Of Spherical Aberrations. Best Used To Replace Single Components Where Performance Must Be Improved.
Material: Combinations Of Two Optical Grade Glasses
OPTICA provides many kinds of high precision prisms, including Penta Prism, Beam splitter Penta Prism, Right Angle Prism, and Corner Cube. Our micro Penta Prism and Right Angle Prism are widely used in optical communication, such as optical switches. For more information about Micro Prism, please refer to “Micro Optics”. Other prisms, such as Dove Prism and Roof Prism are also available upon request.
Coated dove prisms feature a protected aluminum coating with black Krylon paint on the diagonals and are ideal for displaced retro reflection. They provide a U-turn for laser beams.

Equilateral Prism
Lens: Equilateral Prism
Application: Equilateral Prisms Are Normally Used As Dispersing Prisms
Material: BK7
Equilateral prisms have three equal 60° angles and are also referred to as dispersing prisms. Equilateral prisms are used for wavelength separating applications. Optica offers equilateral prisms in both uncoated and anti-reflective versions.
Equilateral prisms are normally used as dispersing prisms. As well as standard BK7 prisms, higher index. SF2 and F2 prisms are offered to increase the dispersive power.

Penta Prism
It is commonly used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. The reflecting surfaces of this Prism must be coated with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum with Black Paint.
Lens: Penta Prism
Application: For Custom Applications, Anti-Reflection Coatings Are Applied To The Entrance & Exit Surfaces.
Material:BK7 Grade A Optical Glass
Penta Prism is a Five –Side prism, It has two important properties, First the image is neither inverted nor reverse while deviated by 90 degree. Secondly, It is a constant deflection device; i.e all the transmitted rays are deviated by the same exact 90 degree. Slight movement of the prism does not effect the true right angle.

Right Angle Prism
Penta Prism is a Five –Side prism, It has two important properties, First the image is neither inverted nor reverse while deviated by 90 degree. Secondly, It is a constant deflection device; i.e all the transmitted rays are deviated by the same exact 90 degree. Slight movement of the prism does not effect the true right angle.
