Optical Surfaces Established Itself as Leading Supplier of High Precision Toroidal Mirrors

Drawing upon over 40 years experience - Optical Surfaces Ltd. has established itself as a leading supplier of high precision plano-convex and plano-concave toroidal mirrors for beam shaping applications.

Benefiting from considerable expertise in manufacturing high performance parabolic reflectors, Optical Surfaces Ltd. also produces top quality grazing incidence toroidal mirror pairs for spectroscopic and imaging applications.

Toroidal mirrors are focusing devices that have two different radii whose axes are oriented at 90° 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 may be combined in one element. The lower number of 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.

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 advanced testing techniques - 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.

Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities. Benefiting from its stable environment, quality testing becomes quantifiable and reliable. All toroidal mirrors are provided with a complete quality test assurance report.
