Prisms

Corner Cube Prisms

: Retro Reflector    : Cube Corner Reflector    : CCP

 

Corner Cube Prism

Corner Cube Prisms (CCP) are triangular prisms consisted of three right angles of 90 degrees. Reflected beam has a characteristic of inevitably returning in the direction of the incoming optical axis. The accuracy is shown with angular deviation (parallelism) between input and output beams. It depends on the mutual perpendicularity of the trihedral surfaces. Using this characteristic, they are often used in survey equipment. Processing from fused silica as well as optical glass is available upon your request.

Triangular Prisms

 

 

Triangular Prism

Triangular Prisms are used for wide optical applications. Two triangular prisms are combined together to act as a beam splitter. They are also used for microscopes, survey equipment and measuring instruments.

Applications: Semiconductors/LCD Lithography Equipment, Microscopes, Survey Equipment, Measuring Instruments, Medical Equipment

Right Angle Prism

 

 

Right Angle Prism

Depending on the usage, the direction of light can be altered 90 or 180 degrees. It also has a function to expand beam according to the angle of incidence.

Beam Path Right Angle Prism
Applications: Digital Cameras

Equilateral Triangle Prism

: Dispersing Prism

 

Beam Path Equilateral Triangle Prism

Equilateral Triangle Prism is used in spectral equipment. Incident beam from a certain angle is resolved into each respective wavelength by the refractive index of the prism. Therefore, it is also called Dispersing Prisms.

Applications: Medical Equipment

Micro Prisms

 

 

 

We are specialized in the manufacturing of various different micro-prisms. All sorts of different micro-prisms are customized dedicated to your own purpose and application. Our X-Cube which consists of four pieces of right angle prisms, can be manufactured in the ultra-miniature size down to 2mm cube with almost seamless bonding and, PBS can be made down to 1.0mm cube. Much more complicated ones like TIR prism can also be made in millimeter order.

 
Applications: Medical Equipment, Endoscopes, Microscopes, Micro projectors and sensors

Penta Prisms

: Pentagonal Prisms

 

Penta Prism

Penta Prisms deviate the input beam by 90 degrees without affecting image orientation. Deviation is independent of prism orientation.

Applications: Survey Equipment, Measuring Instruments

Porro Prisms

 

 

Porro Prism

Porro Prisms are type of reflection prism used in optical instruments to alter the orientation of an image. These consist of a block of glass shaped as a right geometric prism with right-angled triangular end faces.

Beam Path Porro Prism
Applications: Medical Equipment, Cameras, Binoculars

Roof Prisms

: Dachkantprisma

 

Roof Prism

Roof Prisms are in general kind of reflective optical prisms containing a section where two faces meet at a 90 degree angle. Reflection from the two faces returns an image that is flipped laterally across the axis where the faces meet.

Beam Path Roof Prism
Applications: Microscopes, Binoculars

Amici Prism

 

 

Amici Prism

Amici Prism is composed of a roof type prism in the bottom of a triangular prism. The image is inverted and reversed, and made upright. Since the optical axis bends by 90 degrees, it is effective in designs for optical systems with a long optical path. By combining several prisms complex optical systems can be simplified.

 
Applications: Microscopes, Survey Equipment, Measuring Instruments, Binoculars

Penta Roof Prism

: Penta Dach Prism

 

Penta Roof Prism

Penta Roof Prism is mainly installed in the viewfinders of single-lens reflex cameras and has the ability to invert and revert images. As a result, it is able to photograph the angle of view as seen through the viewfinder. There are special Penta Roof Prism and Right Angle Penta Roof Prism that give a constant deviation of 90 degrees.

Beam Path Penta Roof Prism
Applications: Cameras, Microscopes

Schmidt Prisms

 

 

Beam Path Schmidt Prism

Schmidt Prisms is composed of the angle between 45 degrees and 48 degrees between input and output surface. The optical axis is bent 135 degrees, and yet the image can be reversed. The optical axis can be arranged on a line by combining this prism with a supplementary prism and it is used with direct vision binoculars etc.

 
Applications: Binoculars, Survey Equipment
