Precision optical prisms manufactured to customer specifications.
Product Overview
Air-spaced prism assemblies contain two or more prism elements with a defined air gap between selected optical faces.
The air-gap interfaces and prism geometry control reflection and transmission to route light through the specified optical paths.
Prism materials, face angles, gap thickness, relative alignment, mounting requirements, surface quality and coatings can be specified to match your assembly drawings.
Applications
- Projection Optical Engines: An air-spaced prism assembly routes illumination and image light through the optical paths defined by the projection design.
- Imaging & Viewing Modules: An air-spaced prism assembly combines multiple reflections to arrange the viewing path within a compact instrument.
- Optical Test Instruments: An air-spaced prism assembly provides specified reflecting and transmitting interfaces for routing beams between experimental or measurement channels.
