25.4 x 76.2mm EFL 90° Protected Aluminum 100Å Off-Axis Parabolic Mirror

Product Details Aluminum Coatings for UV, Visible, and NIR Applications Range of Surface Roughness, Including 50Å and 100Å 15°, 30°, 45°, 60°, or 90° Offset Angle Options Gold and Silver Coated Off-Axis Parabolic Mirrors Also Available TECHSPEC Aluminum Off-Axis Parabolic Mirrors (OAPs) are a cost-effective solution for focusing incident light with minimal scatter loss. Available with enhanced or protected aluminum coatings, these OAP mirrors offer high reflectivity from the ultraviolet (UV) to the near infrared (NIR). These Aluminum OAPs are manufactured with multiple surface roughness specifications, offering designers the choice between high performance, low scatter mirrors and more cost sensitive options. TECHSPEC Aluminum Off-Axis Parabolic Mirrors are used in optical systems such as Schlieren and spectroscopy systems, as well as in laser systems to focus laser beams. For increased system integration flexibility, mounting plates that thread to the base of these off-axis parabolic mirrors are available.
