Penta Prism
The penta prism is a precision optical element that deflects the incident beam by a fixed 90° angle regardless of the direction of the incident beam. Unlike right-angle prisms, it maintains the original orientation of the image without inversion. The penta prism has stable geometry and high beam steering accuracy, and is widely used in laser alignment, measuring instruments, optical metrology and high-precision imaging systems.

Pentaprism
Prisms
Sunday-optics
Material: BK7, UV fused silica, sapphire, ZnSe, Caf2, Si, Ge, etc. Dimensions: 3mm-380mm Dimensional tolerance [Customer requirements]: +/-0.02mm or Customer requirements
Pentaprisms are widely used in laser levels, imaging, precision systems and optics. Their 90° deviation is independent of prism orientation, making them especially important where orientation cannot be precisely controlled. We manufacture high-precision pentaprisms with customer-specified coatings.
