Product Variants of Infrared Glasses and Materials
Infrared Chalcogenide Glasses (IRG 22 – 27)
When common infrared (IR) materials have reached their limits, infrared chalcogenide glass (IRG) supports demanding applications in terms of cost, performance and processing power. These glasses encompass the common infrared transmission bands 3-5 μm and 8-12 μm, but are able to transmit as low as 0.7 μm.
CHARACTERISTICS
The infrared glass series offered by SCHOTT can also be processed using conventional grinding and polishing techniques, as well as single point diamond turning or molding to support low- to high-volume manufacture.
YOUR ADVANTAGES
- Low dn/dt and dispersion, with high color correction
- Low Tg so moldable for high volume production.
- Lower density than established infrared materials e.g. Germanium.
- Lower price than established infrared materials.
- Conventional processing, meaning no constrains for grinding, polishing and diamond turning.
Sapphire for Advanced Imaging
Sapphire is one of the hardest, most durable and scratch-resistant materials, and offers a broad transmission range from UV to mid infrared wavelengths. It is suitable for use in extreme environmental conditions and can withstand major fluctuations in temperature.
CHARACTERISTICS
With years of experience in infrared glass, SCHOTT can offer sapphire in a wide range of processed shapes according to customer specifications, along with the availability of polished surfaces and customized coatings.
YOUR ADVANTAGES
- Extreme hardness and high mechanical strength.
- High transmission from UV to IR.
- Various shapes from round to square available, and up to 300 mm in diameter.
- SCHOTT uses advanced equipment and state-of-the-art metrology for manufacturing and quality control.
