Changchun Hengyi Optics co., Ltd could manufacture various Optical Prisms, such as Penta Prisms, Right



Angle Prisms, Dove Prisms, PBS Substrate Right Angle Prisms, 45 Degree Reflection Prisms, Roof Prisms, Corner Cube Retroreflectors, Wedges prism, etc.

Right Angle Prisms are usually used to deflect a light beam 90° and 180° as shown. The images passing through the prism are made erect, reversed for 90° deflection and inverted for 180° deflection, respectively.

Angles: 45°, 90°±30", see table

Material: BK7, fine annealed

Flatness: λ/8

Surface Quality: 10-5 scratch-dig

Clear Aperture: 90%

Penta Prisms

¨Neither inverting nor reverse imaging

¨Constant 90°deviation

The penta Prism is a five-sided prism, featuring two important properties. First, the image is neither inverted nor reversed while it is deviated by 90°. Secondly, it is a constant deflection device,i.e. all the transmitted rays are deviated by the same exact 90 degrees. Slight movement of the prisms does not affect the true right angle. This feature makes the prism useful in range-finders. It is also used in viewfinders of single reflex cameras. The reflecting surfaces are enhanced aluminum coated with black paint overcoat for protection.

Beam Deflection: 90°±3' or ±30", see table bellow.

Material: BK7, fine annealed

Dimension: ±0.1mm

Flatness: λ/8 at reflection surface; λ/4 at transmission surface

Surface Quality: 10-5 scratch-dig

Clear Aperture: 90%

Coatings: Reflecting surfaces are aluminum coated with black paint overcoat. Entrance and exit surfaces are MgF2 AR coated

45°Reflection Prisms

¨Constant 45°deviation

The prism is used for 45° beam deflection. The reflection face is aluminum coated with black paint for protection.

Beam Deviation: 45° ± 3'

Material: BK7, fine annealed

Dimension: ±0.1mm

Flatness: λ/8 at reflection surface; λ/4 at transmission surface

Surface Quality: 10-5 scratch-dig

Clear Aperture: 90%

Coatings: specified by customers
