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.Products Name: OHARA Clearceram-Z Ultra-low Expansion glass-ceramic Alias:Ohara Clearceram-Z glass-ceramic, Ohara CCZ glass-ceramic, Ohara CCZ HS glass-ceramic, Ohara CCZ glass, Ohara CCZ HS glass, Ohara Clearceram Ultra-low expansion glass, Ohara CCZ, Ohara CCZ-HS, Ohara Clearceram CCZ,Ohara Clearceram CCZ Hs, OHARA Microcrystalline glass etcMain 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 astronomyThermal Expansion Properties:ModelCoefficient of Thermal ExpansionCCZ Regular0.0±1.0×10-7/?CCCZ HS0.0±0.2×10-7/?CCoefficient of Thermal Expansion of is guaranteed for the temperature range of 0~50°C.Thermal Conductivity:ITEMCCZCCZ HSThermal Conductivity (W/(m?K))1.511.52Thermal Diffusion (×10-4m2/s)0.007620.00775Speci?c Heat (kJ/(kg?K))0.7770.773Mechanical Properties:ItemUnitCCZCCZ HSDensityg/cm3--Yong's ModuleGPa9090Poisson's ratio 0.250.25Compression strengthGPa1.1 Bending strengthMPa116111Tensile strengthMPa55 Torsional rigidityGPa3636Vickers hardnessGPa6.87.0Knoop hardnessKg/mm26.06.4Abrasion Aa*-6264Coefficient of thermal expansioncm/cmoC--Softening pointoC--Annealing pointoC--Strain pointoC--Specific heat(26oC)kJ/kgK2.552.55Thermal conductivity ratio(26oC)cal/cm.sec.oC--Thermal conductivity ratio(100oC)Cal/cm.sec.oC--Main Applying Fields: Applying Fields: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 gyroscope***** Matching 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).
