Product Family Description

  • Protected Silver Coating for Visible and IR Application
  • 100Å Surface Roughness
  • 90° Offset Angle
  • Aluminum and Gold Coated Off-Axis Parabolic Mirrors Also Available

TECHSPEC® Silver Off-Axis Parabolic Mirrors (OAPs) are designed to direct and focus incident collimated light at a specific offset angle with minimal scatter loss. Coated with protected silver, these OAP mirrors provide high reflectivity from the visible to the infrared (IR), making them ideal for broadband applications. These Silver OAPs provide unobstructed access to the point of focus, allowing for the creation of more compact systems. TECHSPEC® Silver Off-Axis Parabolic Mirrors (OAPs) are commonly used in instrumentation and laser systems in the visible and IR spectrum, including Schlieren, MTF, FLIR, and FTIR systems. For additional surface roughness options and offset angles, please see our aluminum or gold coated OAPs or contact us for custom options.
