Prisms
Corner Cube Prisms
: Retro Reflector : Cube Corner Reflector : CCP
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. |

Hollow Cube Prisms
: Hollow Retro Reflector
Hollow Cube Prism are constructed of tree first surface mirrors assembled into corner cubes. | |||
|
Dichroic Prisms
Dichroic Prisms combine R (red), G (green) and B (blue) beams from three directions into one direction. |
|||
|
Cross Dichroic Prism (X-cube)
Cross Dichroic Prism (X-cube) is combination of 4 triangular prisms. It has function of combining R, G and B three color beams to form the color image. NITTO OPTICAL has a capability for producing various size of X-cubes from 2mm to 60mm and larger for any projectors. |

|
Dichroic Prisms - Philips Type
Philips Type Prism is used to separate or combine the 3 primary color (RGB) beams. |
|||
|
RGB Prism for 3CCD Video Camcorders
RGB prism is used for 3 CCD video camcorders. |
|||
|
Dichroic Prism - Kester Type
Kestrer Type Dichroic Prism is used to separate or combine the RGB beam.
|
Total Internal Reflection Prisms
: TIR Prisms
Total Internal Reflection Prisms (TIR prisms) are used for DLP projectors. These are combined with two triangle prisms. |
|||
|
Triangular Prisms
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.
|
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. |
|||
|
Equilateral Triangle Prism
: Dispersing 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.

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. |

Penta Prisms
: Pentagonal Prisms
Penta Prisms deviate the input beam by 90 degrees without affecting image orientation. Deviation is independent of prism orientation. |
|||
|
Porro Prisms
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. |
|||
|
Roof Prisms
: Dachkantprisma
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. |
|||
|
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. |

|
Penta Roof Prism
: Penta Dach 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. |
|||
|
Schmidt Prisms
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. |
|||
|
Dove Prisms
: Image Rotation Prisms
Dove prisms are types of reflected prism which is used to invert an image. Dove prisms are shaped from truncated Right Angle Prism. |
|||
|
Rhomboid Prisms
Rhomboid Prisms are used to displace a laser beam without changing its direction. |
|||
|
Polygon Prisms
Polygon Prisms are used to deviate light-beam. |
|||
|
Expander Prism
: Littrow Dispersing Prism
Beam Shaping Prisms are, in general, used as a beam shaper in laser diodes. The optical axis can be adjusted in a parallel direction by combining two of these prisms. |
|||
|
Wedge Prisms
Wedge prism slightly tilts the angle of an incident beam and adjusts its efficiency. Wedge prism adjusts the aspect ratio of the semiconductor elliptical beam and focuses the beam efficiently.
