Quartz glass for precision optics

Infrasil and Suparsil quartz glass combine excellent physical and optical properties. While Suprasil quartz is produced by flame hydrolysis, Infrasil is natural quartz glass. Lenses, windows and filters made from Infrasil or Suprasil are the optimum choice for all precision applications;

Suprasil

The quartz glasses produced by flame hydrolysis of SiCl4 combine excellent physical and optical properties. High-purity synthetic quartz has excellent optical properties from the UV to the NIR range.

Infrasil

Optical quartz glasses are mostly used for applications from the VIS to the NIR range. In addition, synthetically produced quartz glasses are the cost-effective alternative to Suprasil. The glass types Infrasil 301, 302 and 303, which are melted from natural raw materials, are particularly suitable for IR applications.

Applications

Infrasil and Suprasil glasses are ideal for applications where low absorption and optical performance are required.

Suprasil: prisms, beam splitters, UV windows, mirrors
Infrasil: prisms, IR lenses, IR windows, mirrors
Mirrors and windows for laser diodes
Mirrors and windows for Nd:YAG lasers
Lenses, prisms and filters for the NIR
