Light Guide Prism

The Light Guide Prism is an optical light-guiding component designed to control, redirect, split, or reshape light within an optical system. It is not limited to a single prism configuration; different prism geometries can be selected according to the required light path and optical function.

Available Light Guide Prism configurations include:

• Right Angle Prism

• Dove Prism

• Beam Splitter Prism

• Penta Prism

• Corner Prism

• Trapezium Prism

• Rhomboid Prism

• Roof Prism

• Cube Prism

• Customized Prisms

The prism configuration can be selected based on the required beam direction, reflection path, image orientation, beam splitting function, or optical system structure.

Light Guide Prism Specifications

Prism Types

Right Angle Prism

Used for 90° beam deviation and compact optical path arrangements.

Dove Prism

Suitable for applications requiring image rotation or beam-direction manipulation.

Beam Splitter Prism

Designed to divide incident light into separate optical paths according to the specified splitting requirements and coating configuration.

Penta Prism

Provides a fixed beam deviation and is suitable for optical systems requiring stable beam redirection.

Corner Prism

Used for compact beam folding and directional changes within optical assemblies.

Trapezium Prism

Provides customized beam deviation and light-path control for specific optical configurations.

Rhomboid Prism

Suitable for lateral beam displacement while maintaining the general beam direction.

Roof Prism

Used in optical systems where beam folding and image handling are required.

Cube Prism

A compact prism configuration for beam manipulation, splitting, or integration into space-constrained optical assemblies.

Customized Prism

Custom prism geometry, dimensions, angles, optical specifications, and coatings can be configured according to customer optical system requirements.

Optical Performance Options

The Light Guide Prism can be specified with different precision levels depending on the application.

Flatness:
Available from 2λ to λ/10 for applications requiring controlled optical surface accuracy.

Surface Quality:
Options range from 80/50 to 10/5, allowing the prism to be matched to different optical performance requirements.

Angle Tolerance:
Precision angle control can range from 3′ to 15″, depending on prism configuration and application requirements.

Clear Aperture:
Effective optical aperture can be specified at more than 85%–95%, according to component design.

Optical Coating

The coating specification can be customized according to the wavelength and functional requirements of the optical system.

Coating selection may be determined by:

• Operating wavelength

• Required transmission or reflection

• Incidence angle

• Beam-splitting requirements

• Environmental conditions

• Optical efficiency requirements

Customer-specified coating requirements can be incorporated into the Light Guide Prism configuration.

Custom Light Guide Prism

For optical systems requiring non-standard beam paths or installation dimensions, customized prism solutions are available.

Customization can cover:

• Prism type

• Overall dimensions

• Prism angles

• Optical surface accuracy

• Surface quality

• Clear aperture

• Chamfer dimensions

• Optical coating

• Application-specific optical requirements

The appropriate prism structure and optical specifications can be selected according to the required light path and system configuration.
