An Off-Axis Parabolic (OAP) mirror can collect collimated light and focus it at a specific angle outside the incoming light path. As a reflective optic, chromatic aberration is eliminated and a detector, at the focal point, does not interfere with the incoming light path. OAPs are used in LIDAR/LADAR systems and other laser scanning applications requiring collection of reflected light.
We offer 4” and 6” OAPs as standard product but can make much larger sizes custom. We welcome your specifications for custom OAPs and other freeform metal optics coated for laser scanning applications.
