High-quality Custom Toroidal Mirrors

Dec 20 2005

Drawing upon a highly stable manufacturing environment, Optical Surfaces Ltd has established a strong reputation for supplying high-quality custom toroidal mirrors for spectrophotometry (UV, IR), X-ray crystallography, mass spectrometry and synchrotron applications.

Toroidal mirrors are focusing devices having two different radii whose axes are oriented at 90° to each other. They are utilised in instances where a beam must be focused and folded. Rather than using both a spherical mirror and a plane mirror for this purpose, both functions may be combined in one element. The lower number of optical elements increases energy throughput and also allows for more compact designs. Toroidal mirrors also correct for the astigmatism that results when a spherical mirror is used off axis.

With workshops and test facilities deep underground where temperatures remain constant and vibration is practically non-existent Optical Surfaces Ltd. routinely 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. Working with a comprehensive inventory of tools and test plates Optical Surfaces Ltd. can produce both 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.
