High Precision Roof Prism (Amici) for Image Erection and Beam Deviation

Precision Roof Prism (Amici Type)

The Precision Roof Prism (Amici Type) is a high-accuracy optical component engineered to deviate an incident beam by 90° while producing an erect, laterally correct image. It is specifically designed for applications requiring compact optical layouts without compromising image fidelity.

Manufactured from high-quality optical glass, the prism features a finely polished roof edge, where two reflective surfaces meet at a precise 90° angle. This geometry enables exact image erection and beam redirection, while maintaining excellent optical performance. Strict control over angular accuracy and roof edge sharpness ensures minimal image degradation and high contrast output.

Each prism is fabricated using advanced polishing techniques to achieve superior surface flatness, low wavefront distortion, and high dimensional precision, making it suitable for both standard and high-performance optical systems.
