On-Axis Parabolic Mirrors

KENLEY, England — On-Axis Parabolic MirrorsFast-focusing on-axis parabolic mirrors from Optical Surfaces Ltd. are precisely manufactured to customer specifications and supplied with full surface quality test data.

The effective f-number that can be achieved with the devices is lower than an off-axis paraboloid, allowing more energy to be concentrated. Generally, alignment of on-axis parabolic mirrors is less critical, thus easier. Circular and irregularly shaped on-axis parabolic mirrors can be produced with a surface accuracy of >λ/20 pv and a microroughness of typically <1.2 nm rms.

Combining these features with an extensive array of high-reflectivity coatings enables researchers to achieve the high optical performance and efficiency required by demanding experiments.
