Off-Axis Parabolic Mirror

Product Info

Off-Axis Parabolic (OAP) Mirrors are first-surface mirrors whose reflective surfaces are equivalent to segments of a parent parabolic mirror. They achromatically focus a collimated beam or collimate a broadband point source, and their off-axis design spatially separates the focal point from the rest of the beam path. The all-reflective design eliminates phase delays and absorption losses introduced by transmissive optics and makes them well suited for use with femtosecond pulsed lasers. They are available with coatings below: UV-enhanced aluminum, protected aluminum, protected silver and gold.
