Edmund Optics Inc. 101.6 x 304.8mm 30 Degree Off-Axis Parabolic Aluminium Mirror NT83-967

Aluminum Substrate Mirrors Available in 15°, 30°, 45°, 60°, or 90° Off-Axis Options Aluminum and Gold Coating Options Unlike standard parabolic mirrors, Off-Axis Parabolic Metal Mirrors direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point. Typically, these mirrors are used as collimators in Schlieren and MTF systems, but gold coated off-axis parabolic mirrors can also be used in FLIR test systems. Note: Due to the 175å surface roughness, these mirrors are not suitable for visible and UV applications that require low scatter.To ease mounting, all 25.4mm diameter mirrors have three 6-32 TPI tapped holes on a ¾" bolt circle, all 50.8mm diameter mirrors have three 6-32 TPI tapped holes on a 1.25" bolt circle, and all 76.2mm and 101.6mm diameter mirrors have three 8-32 TPI tapped holes on a 2.25" bolt circle.
