Product Family Description

  • Aluminum Substrate Mirrors
  • Available in 15°, 30°, 45°, 60°, or 90° Off-Axis Options
  • Protected Aluminum, Protected Gold, and Bare Gold Coating Options

Off-Axis Parabolic Metal Mirrors (OAPs) are not wavelength dependent and free of aberrations across a broad spectrum. These benefits make OAPs ideal for use in instrumentation and laser systems like Schlieren, MTF, FLIR, FTIR systems and IR lasers such as Quantum cascade lasers. These mirrors provide unobstructed access to the point of focus permitting designers to create more compact systems. Off-Axis Parabolic Metal Mirrors are available in a variety of off-axis and coating options, and are widely used in broadband UV, Visible, and IR applications. If Scattering in the UV and Visible spectrum is a concern, please consider our our Low Scatter 50 Å surface roughness OAPs.

Note For new 100 angstrom options, please consider our TECHSPEC® 100Å Off-Axis Parabolic Mirrors.
