76.2 x 76.2mm EFL 90° Protected Silver 100Å Off-Axis Parabolic Mirror

Product Details 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.
