Product Description General Introduction:Raytek offers OHARA Microcrystalline glass and Schott Microcrystalline glass widely used in optical system. This material was developed by OHARA based on our knowledge of High Homogeneity melting and Precise Crystallization. This material is produced under tightly controlled conditions and offers outstanding thermal, mechanical and chemical properties. Glass Ceramics has a very low thermal expansion rate, so it is essential for a large number of demanding high-tech applications that require extremely high accuracy.Main Characteristics:Extraordinary features1) The zero expansion glass ceramics have special properties. When the temperature changes, the change of geometry and distance is almost zero.2) Very low coefficient of thermal expansion (CTE), suitable for a wide range of temperatures3) Excellent CTE uniformity throughout the material4) The degree of defect is very low5) A variety of accurate geometric shapes can be obtained by grinding process6) When the residual roughness is less than 1 nm, the surface may be very smooth7) Excellent chemical stability8) All of these features enable extraordinary reproducibility for small components and for large ton telescopes used in astronomyMain Applying:High tech applicationZero expansion glass ceramics have become a decisive factor in the performance and quality of many modern technology applications as following:1).Platform and mirror for IC and LCD lithography equipment2).Mirror substrate for segmented and large monolithic telescopes3).Ultra light weight mirror blank4).Technical standard for precision measurement5).High precision mechanical parts, such as ring laser gyroscopeMatching Custom Manufacturing Serivce:Including Moulding, CNC machining, Polishing, Particle beam processing, Magnetic flux conversion processing, Grinding, Coating, Lightweighting, Custom Shaping, Counterbores, Drilling & Coring, Edge & Bevel Polishing,3D Contouring, Bevels & Chamfers, Steps & Slots, Laser Cutting & Marking, Metrology & Inspection, Precision Pitch Polishing, Double-Sided Polishing, Optical Assembly, Measuring, etc.Matching processing equipments;1).Single side lapping and polishing machines2).Duble sided polishing machines3).Ring throwing machines4).DMG five-axis five-linkage spherical milling machine5).DMG ultrasonic machining center6).Super large scale gantry cnc machining center (2.0*2.0m)7).Super large scale surface grinder (1.6m*1.6m)8).CNC cutting machines9).Thin plate cleaning machines10).Ultrasonic trough cleaning machines11).Plane interferometers12).Two dimensional detectors13).Ion beam polishing machines14).Magnetorheological polishing equipmentsMain Cooperation Materials Manufacturers: CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,C-LASER,ETCMain Export Countries & Areas: Usa, Uk, Japan, Germany, Spain, France, Swiss, Korea, Russia, Pakistan, India, Portugal, Canada, New Zealand, Australia, Saudi Arab, Turkey, Finland, Poland ,etc.Raytekoptics Extra value added services offered:1).
