Off-Axis Parabolic Mirrors with Alignment Through Holes

Through Holes Parallel to Focused and Collimated Beams
Range of Metallic Coatings Available
<50Å RMS Surface Roughness

TECHSPEC® Off-Axis Parabolic (OAP) Mirrors with Alignment Through Holes are designed with two through holes, one that aligns with the focal point of beams focused off the parabolic surface and the second parallel to beams collimated by the surface. The hole placements allow for two beams to hit a target or sample simultaneously, which is a technique used to take pump-probe measurements. These OAPs feature aluminum substrates and are diamond turned with a surface roughness of <50Å RMS that minimizes scatter. TECHSPEC Off-Axis Parabolic Mirrors with Alignment Through Holes are available coated with protected gold, protected aluminum, or UV enhanced aluminum for integration into applications requiring high reflectance from the ultraviolet (UV) to the infrared (IR).

Note: Please contact us for custom options if your application requires a standard OAP Mirror with a through hole.
