Focuses collimated light without chromatic aberration. Its off-axis design provides more space around the focal point for sensors and external detectors.
Off-Axis Parabolic (OAP) Mirrors are available with four coating options: UV-enhanced aluminum (250 - 450 nm), protected aluminum (450 nm - 20 µm), protected silver (450 nm - 20 µm), and protected or unprotected gold (800 nm - 20 µm), designed for collimating or focusing broadband light.
We also offer vacuum-compatible 90° off-axis parabolic mirrors with options for UV-enhanced aluminum, protected silver, and protected gold coatings. These vacuum-compatible OAP mirrors are diamond-turned to achieve an RMS surface roughness of <50 Å, minimizing scattering to the greatest extent
