ANTGLASS supplies and processes Chalcogenide Infrared Glass for optical, electronic, laboratory and industrial components made to customer drawings.
Material Overview
Chalcogenide Glass: Amorphous sulfur/selenium/tellurium-based IR glass; IRG 22: Chalcogenide infrared glass; IRG 24: Chalcogenide infrared glass; IRG 25: Chalcogenide infrared glass. The material system is described as Amorphous sulfur/selenium/tellurium-based IR glass. Selection begins with the exact grade, wavelength or optical function, thermal and chemical environment, starting form, finished geometry and inspection method. The material record is kept separate from the finished-part drawing so that grade data and manufacturing requirements remain traceable.
Applications associated with this material include Thermal imaging, gas sensing, compact molded IR lens systems, night vision, gas detection, laser windows. ANTGLASS uses the approved material and drawing to manufacture blanks and finished parts rather than treating a published material property as a universal component guarantee.

Design Rules for a Manufacturable RFQ
- Define the wavelength band, crystal orientation where relevant, coating and environmental exposure.
- Dimension critical surfaces, edges, holes, slots and datums separately on the drawing.
- Identify optical, sealing, bonding, coated and cosmetic zones before quotation.
- Match inspection methods to the functional tolerance and surface requirement.
- State prototype and production quantities together with cleaning and packaging needs.
Quality Risks and Inspection
Specialty optical materials can be soft, brittle, anisotropic, moisture-sensitive or temperature-sensitive. Use a material-specific machining, coating, cleaning and mounting design.
- Material identity and source documentation
- Dimensions, thickness and feature position
- Clear aperture, scratch-dig or cosmetic zone and transmitted-light inspection
- Edge chips, cracks and surface condition
- Cleaning, orientation and protective packaging
Applications and Product Connections
- Thermal imaging
- gas sensing
- compact molded IR lens systems
- night vision
- gas detection
- laser windows
- spectroscopy
- domes
Material Comparison and Alternatives
Compare Chalcogenide Infrared Glass with Fused silica for UV-visible, sapphire for harsh windows, chalcogenide glass for molded IR optics.. Substitution should preserve the functional wavelength, refractive or spectral behavior, thermal expansion, temperature range, chemical durability, mechanical behavior, starting form and component cost.
