Penta Prism Beamsplitters
- Clear Aperture (%): >90
- Dimensional Tolerance (mm): ±0.10
- Surface Quality: 40-20
- Surface Flatness (P-V): λ/4
Penta Prism Beamsplitters are high-precision optical prisms designed to split a beam into two paths with a fixed 90° deviation.
Also, they ensure the output beam is deviated exactly by a right angle, regardless of the prism’s orientation.
Therefore, this feature makes them an excellent choice for applications requiring stable and accurate beam alignment.
What is a penta prism used for?
In SLR cameras, surveying instruments, laser alignment systems, binoculars, and other optical devices.
