Off-Axis Parabolic Mirrors

About OAP Mirrors

Off-Axis Parabolic (OAP) Mirrors are precision optical components designed to focus or collimate light without introducing spherical aberrations. Unlike traditional parabolic mirrors, OAP mirrors are cut at an angle, enabling unobstructed access to the focal point. This makes them ideal for applications requiring high precision, minimal distortion, and compact optical designs.

Key Benefits of OAP Mirrors:

  • Distortion-Free Focus: Eliminates spherical aberration for high-fidelity imaging.
  • Compact Design: Off-axis configuration reduces the need for bulky setups.
  • Versatile Compatibility: Works across a wide range of wavelengths and applications.
