Frequently Asked Questions

Off-Axis Parabolic (OAP) Mirrors are used to focus a collimated beam or collimate a divergent source in various applications such as target simulators, collimators, MTF measuring systems, spectroscopic and FTIR systems, radiometers, beam expanders, and laser divergence measuring systems.

The standard sizes available for the Reflective Focal Length (RFL) of OAP Mirrors are 1 inch, 2 inches, 4 inches, and 6 inches.

Yes, the off-axis angle of OAP Mirrors can be customized. The standard off-axis angle is 90°, but other angles can be designed according to the customer's requirements.

The surface roughness of OAP Mirrors is <150 Å (RMS), but it can be customized to be as low as <20 Å (RMS) according to the customer's needs.

The available coatings for OAP Mirrors are Protected Aluminum (400-2000nm), Protected Silver (450nm - 2000nm), Protected Gold (700nm - 2000nm), Bare Gold, and UV Enhanced Aluminum.
