Optics for Infrared

IR light is used in many optical components and systems, including IR imaging and vision applications, some long-wavelength emitting lasers, and other lasers. Since many intriguing jumps, like those used to identify trace gases, occur in the IR, spectroscopy is a significant application field as well.

For a long time, Alfa Chemistry has been a key player in the IR optics industry. We have invested a lot of time and money in developing precision optical crystals and components since we are a leader in offering cutting-edge optical goods and their bespoke designs. These components are used in a number of IR optics applications. Commonly used IR optical components include lenses, beam splitters, prisms, filters, optical windows and polarizers. The cornerstone of our business is providing high-quality items, and all of them adhere to rigid requirements.
