Rhomboid Prism
Rhomboid Prisms are precision optical components designed for lateral beam displacement while maintaining the original beam direction. The parallel entrance and exit faces allow light to be shifted without changing the image orientation. Chenyu Optics manufactures rhomboid prisms in BK7, fused silica and UV fused silica with custom dimensions and coatings.
Rhomboid Prism Overview
Rhomboid Prisms are precision optical components designed for lateral beam displacement while maintaining the original beam direction. The parallel entrance and exit faces allow light to be shifted without changing the image orientation.
They are commonly used in laser systems, optical alignment assemblies, imaging instruments and precision measurement equipment requiring controlled beam displacement. Unlike Dove prisms, rhomboid prisms do not rotate or invert the image.
Chenyu Optics supports custom rhomboid prism manufacturing according to customer drawings, including custom size, displacement distance and coating design for prototype and repeat production.
