ULTRA-PRECISION FLOAT POLISHING OF OPTICAL MATERIALS Yoshiharu Namba Chubu University, 1200 Matsumotocho, Kasugai, Aichi 487-8501, Japan 1. Introduction The float polishing process has been originally developed for making ultra-smooth sapphire surfaces1) in order to develop the silicon-on-sapphire (SOS) devices.

In theory, the process requires a minimum of three parts. The actual number is determined by part quantity, part size, and machine size. With double-sided lapping and polishing (DSLP), the optical components are held in geared or sprocketed carriers that are driven in a planetary motion covering the full surface of the lapping plates and are subject to continually changing direction of rotation.

A series of controlled grinding experiments, utilizing loose or fixed abrasives of either alumina or diamond at various particle sizes, were performed on a wide range of optical workpiece materials [single crystals of Al2O3 (sapphire), SiC, Y3Al5O12 (YAG), CaF2, and LiB3O5 (LBO); a SiO2−Al2O3−P2O5−Li2O glass ceramic (Zerodur); and glasses of SiO2:TiO2 (ULE), SiO2 (fused

Lens Grinding & Polishing Specialized Lens Generating and Polishing Equipment allows Insaco to Manufacture a wide variety of Lens in Sapphire and other Optical Materials. Insaco Inc.

This lapping materials can exerts its excellent effect of processing performance for not only semiconductor crystal wafers but also other optical materials, such as a lens, prism, glass material, etc. Moreover, it can safely be used for other highly value-added workpieces as well.

Chatter that limits ground surface finish has been observed in the deterministic microgrinding of brittle optical materials. In this article, the classical single degree of freedom model for chatter, accounting for both work and tool regenerative effects, is adapted for contour grinding optical surfaces.

This 20-minute webinar will focus on the capabilities and benefits of OptiSonic: OptiPro's innovative ultrasonic grinding machine for efficient processing of optical glasses and ceramics. Learn how OptiSonic can have a positive impact on your company's bottom line by greatly reducing cycle times, even while machining the most challenging materials.

The machine grinds each lens to its proper shape and places a bevel around the edge of the lens so that the lens will fit the eyeglass frames. Water flows over the lens throughout this process. 10 If the lenses require additional grinding, the process is done by hand using a mounted power grinder.

Optical polishing is the precipice of optical fabrication. It is the department that without, one wouldn’t have finished optics. Our polishing department is truly one of the most unique and critical departments within Precision Optical. It balances ancient recipes of optical craftsmanship, with modern technology.

KDP is a perfect material in application for diamond turning, because the material is very desirable for its optical modulating properties, yet it is impossible to make optics from this material using conventional methods. KDP is water-soluble, so conventional grinding and polishing techniques are not effective in producing optics. Diamond
