GCL-0304 Right Angle Roof Prisms

 

This type of prism consists of a roof edge produced upon the long reflecting face of a right-angle prism and is also called Amici roof prism. Like a right-angle prism, it reflects an image by 90°, but inverts the image simultaneously. It is commonly used as an erecting system in telescopes.

• Material:                                  BK7, fine annealed
• Dimension Tolerance:               ±0.15
• Flatness:                                  λ/4 at reflection surface
                                                 λ/2 at transmission surface
• Roof Angle Tolerance:             ±5", ±15''
• Surface Quality:                       60-40 scratch-dig
