Sizes, tolerance, accuracy class of in-process part, methods
Our skilled specialists with more than 20 years of optical fabrication expertise are ready to respond to a wide range of challenges.
Our state-of-the-art technology fitted with precision-machining centers such as: SCHNEIDER SCG S2/1, SCP 100 S2/2, Spheroline SLG 301, measuring systems for high-precision measurements of optical details 2DETAM of Canoscan 755 Hommel-Etamic JENOPTIK, Super-SPHEROTRONIC TRIOPTICS PrismMaster PRO enables fabrication of any surface shape products, with a precision accuracy.
We offer the following services:
Our advanced, state of the art equipment, unrivaled throughout Russia allows us to grow large-sized solid materials of high-purity, such as polycrystal Zinc selienide by chemical vapor deposition method (CVD method). Process unit capacity is 500 kg of solid material per month, with maximum sheet sizes of 1320х680х25 mm, and up to 800 kg per month with maximum sheet sizes of 1320х1200х40 mm.
R’AIN Optics departments are equipped with the up-to-date machinery to maintain material roughing work, blanks production, initial polishing, as well as production of complex, shaped form pieces and final polishing of the optical elements.
Moreover, the company is fitted up with the advanced testing and measuring equipment that can be used to respond to not only production challenges, but also scientific ones. The following step after Zinc selienide synthesis is the production of Zinc selienide blanks. At this stage we are able to manufacture a wide range of Zinc selienide blanks, both of the basic shapes, such as rectangle and circle shapes, and of complex polyhedron shapes. The sizes depend on the different optical properties requirements, and can be up to 1320х1200х40 millimeters. The blanks surface quality is defined in the technical design specification and is agreed upon with the customer.
The stock-list of the manufactured optical elements:
Tolerances for overall dimensions of any product are set in accordance with the customer’s technical design specification. Each order starts with the drawings, developed according to Unified System of Engineering Drawings. Unified System of Fits and Tolerances is applied in assigning the tolerances. Diameter accuracy of the products is up to 0.02 mm, and thickness accuracy of the products is up to 0.02 mm.
We produce ZinSe optical materials up to 3rd class of surface finish.
