101.6 x 101.6mm EFL 90° Protected Gold 100Å Off-Axis Parabolic Mirror

Product Details Bare or Protected Gold Coating for NIR and IR Applications 50Å and 100Å Surface Roughness Options 15°, 30°, 45°, 60°, or 90° Offset Angles Aluminum and Silver Coated Mirrors Also Available TECHSPEC Gold Off-Axis Parabolic Mirrors (OAPs) are designed for minimal scatter loss in light focusing applications. Available with bare or protected gold coatings, these OAP mirrors offer excellent reflectivity from the near infrared (NIR) to the far infrared (IR). Multiple surface roughness options are available in offset angles from 15 to 90°, providing flexibility for system designs. TECHSPEC Gold Off-Axis Parabolic Mirrors are commonly used in IR systems such as FLIR and FTIR, as well as IR lasers including quantum cascade lasers (QCLs). Mounting plates with holes perpendicular to the optical axis for post mounting are also available.
