Custom Off-Axis Paraboloids
Optical Surfaces Ltd.Request Info
Optical Surfaces Ltd. can typically produce off-axis parabolic
mirrors up to 600 mm in diameter with surface accuracies to λ/20 peak-to-valley,
depending upon off-axis angles. With proprietary polishing techniques, the company
can, depending upon the surface accuracy required, achieve the natural limit to
the off-axis angle of around 25° to 30° and surface micro-roughness on
aspherics of ~1 nm rms. Coatings are available for standard and custom components
from metallic, with or without protective overcoat, to multilayer dielectrics and
ultrahard coatings. Applications include high-power laser focusing, focusing upon
astronomical objects, collimating reference wavefronts, beam expansion, median time
to failure measurement, minimum resolvable temperature difference testing and boresight
alignment for missile guidance systems.
