SUPRASIL1 e SUPRASIL2
SUPRASIL1 and SUPRASIL2 (Grade A & B) are high purity synthetic fused silica materials manufactured by flame hydrolysis of SiCl4. They combine excellent physical properties with outstanding optical characteristics in the deep UV and the visible wavelength range. The index homogeneity is controlled and specified either in one direction (the direction of use or functional direction) or even in all three dimensions. In addition, SUPRASIL1 und SUPRASIL2 (Grade A & B) the materials provide excellent resistance to damage by high energy radiation especially in UV-Laser-applications.
All synthetic fused silica SUPRASIL grades are practically free from bubbles and inclusions.
The optical homogeneity, which is the main criterion for very low transmitted wavefront distortion, refers to three categories:
  • SUPRASIL 1 is an optically isotropic 3D-material. It is highly homogeneous and has no striations in all three dimensions. These properties are very important for multiple axis optics such as prisms, steep lenses, beam splitters, etalons or retroreflectors.
  • SUPRASIL 2 Grade A & B are homogeneous in the primary functional direction. Weak striations, if any, are parallel to the major faces and do not affect the optical performance.
  • SUPRASIL 2 Grade A & B are the preferred materials for demanding optics in one directional use such as lenses, UV-laser windows, optical flats.
SUPRASIL 311 e 312
SUPRASIL 311 and 312 are high purity synthetic fused silica materials manufactured by flame hydrolysis of SiCl4. They combine excellent physical properties with outstanding optical characteristics in the deep UV to the near IR. The most prominent property of SUPRASIL 311 and 312 is the high degree of index homogeneity which is controlled and specified either in one direction (the direction of use or functional direction) or even in all three dimensions. In addition, SUPRASIL 311 and 312 provide a high degree of resistance to radiation damage and are therefore the preferred materials in high energy laser applications.

  • SUPRASIL 312 is the preferred material for demanding optics in one directional use such as laser windows, optical flats, lenses.
  • SUPRASIL 311 and 312 are the preferred materials for UV-microlithography, interferometry, special laser applications, VUV applications, high quality retroreflectors and prisms, etc. In the DUV, SUPRASIL 311 and 312 show the highest transmission of all SUPRASIL grades.
