Optical Surfaces' high-precision Plano-convex and Plano-concave toroidal mirrors are suitable for beam-shaping applications.
Optical Surfaces also produces top-quality grazing incidence toroidal mirror-pairs for spectroscopic and imaging applications.
Toroidal mirrors are focusing devices with two different radii, the axes of which are oriented at 90 degrees to each other.
Toroids offer advantages where a beam must be focused and folded.
Rather than using both a spherical mirror and a plane mirror for this purpose, both functions can be combined in one element.
Fewer optical elements increases energy throughput, saves money and also allows for more compact designs.
Toroidal mirrors also correct for the astigmatism that result when a spherical mirror is used off axis.
Optical Surfaces produces custom toroidal-mirrors in a range of materials (Zerodur, BK7, Fused Silica) with typical surface-accuracy of better than lambda/5 (dependent on size and radius) and surface quality of 20:10 scratch dig.
Optical Surfaces can produce Plano-convex and Plano-concave toroidal mirrors in a range of shapes (largest dimension up to 400mm) with high performance and durable optical coatings that provide superior image quality.
Optical Surfaces' ISO 9001-2000-approved manufacturing facility provides the flexible resources to supply from single specialist-requirements to OEM quantities.
All toroidal mirrors are provided with a complete quality-test assurance report.
