Highly Aspheric Mirrors and Lenses

altOptical Surfaces Ltd (Surrey, UK) can generate highly aspheric parabolic mirrors with off-axis angles approaching 30 degrees and focal lengths as short as 100mm. They can also fabricate high-performance aspheric lenses with tight tolerances. Excellent performance is achieved with low surface scatter (20-10 scratch-dig) and high surface accuracy (lambda/20). The complex surface profile of aspheres offers excellent correction of spherical aberration and reduces other optical aberrations compared to a simple lens or mirror. On-axis parabolic mirrors produce collimated reflected light and are used in applications that require very fast focusing and high energy densities. Off-axis parabolic mirrors provide an unobstructed aperture allowing complete access to the focal region.
