ANTGLASS supplies and processes Corning HPFS Fused Silica for optical, electronic, laboratory and industrial components made to customer drawings.
Material Overview
HPFS 7980: High-purity synthetic fused silica. The material system is described as High-purity synthetic fused silica. 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 UV windows, laser optics, semiconductor parts, lamps, high-temperature windows, precision substrates.. 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.

Actual source size and thickness are matched to the order, while the finished component is controlled by the drawing.
- Drawing and material-grade review
- Blank preparation and geometry planning
- Diamond cutting, CNC machining, drilling and controlled grinding
- Lapping, optical polishing, ultrasonic cleaning and inspection
ANTGLASS can manufacture related products including Laser Windows, Precision Optical Glass Windows, Glass Wafers, Glass Carrier Wafers. Projects that need material selection, prototype validation, optical performance or harsh-environment review can also use the related solutions: Semiconductor, MEMS & Advanced Packaging Glass, Optical, Sensor & Machine Vision Glass.
Design Rules for a Manufacturable RFQ
- Provide wavelength range, OH or purity needs and laser or thermal conditions where relevant.
- 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
Avoid subsurface damage, contamination and an incorrect silica grade for the wavelength or OH requirement. Finished optical performance also depends on polish and coating.
- 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
- UV windows
- laser optics
- semiconductor parts
- lamps
- high-temperature windows
- precision substrates.
Material Comparison and Alternatives
Compare Corning HPFS Fused Silica with Borosilicate for moderate temperature and lower cost, CaF2 or MgF2 for deeper UV, sapphire for abrasion resistance.. Substitution should preserve the functional wavelength, refractive or spectral behavior, thermal expansion, temperature range, chemical durability, mechanical behavior, starting form and component cost.
