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 etc
Main Characteristics:
Extraordinary features
1) 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 temperatures
3) Excellent CTE uniformity throughout the material
4) The degree of defect is very low
5) A variety of accurate geometric shapes can be obtained by grinding process
6) When the residual roughness is less than 1 nm, the surface may be very smooth
7) Excellent chemical stability
8) All of these features enable extraordinary reproducibility for small components and for large ton telescopes used in astronomy
