Coresix Precision Glass

What Coresix Precision Glass does

Coresix Precision Glass is a privately held precision glass fabrication company headquartered in Williamsburg, Virginia, founded in 2002 with 51-100 employees. The company manufactures custom glass components and glass wafers to tight dimensional, spectral, and surface-quality specifications for enterprise customers in aerospace, avionics, semiconductor, biotech, display, and optics markets. Its process stack spans mechanical scribing, CNC edging/grinding, single- and double-side lapping and polishing, ultrasonic cleaning, chemical strengthening, laser marking, and inspection, all culminating in packaging inside a Class 100 Optical Clean Room. The company emphasizes capabilities in ultra-thin glass handling (down to 100μm), sub-micron defect detection, total thickness variation below 1μm, and surface roughness as low as 2Å RMS, supported by advanced metrology including Zygo interferometers, SmartScope optical CMMs, and a Tropel FlatMaster 200. Materials processed include Corning Eagle XG, Willow Glass, Lotus NXT, HPFS Fused Silica, and Corning 7740, alongside SCHOTT B 270 i, D 263, N-BK 7, Borofloat 33, and Pilkington Optiwhite, giving Coresix access to virtually the full specialty-glass supply chain.

Coresix operates a direct, sales-led B2B model with no distributors or resellers. Pricing is quote-based and custom per specification, with customers initiating contact via a website request form, email to [email protected], or phone. The company holds ISO 9001:2015 certification (ANAB) and ships globally, including to space programs — its solar cover glass has flown on Mars missions. The Display segment accounts for approximately 50% of total sales, while biotech is described as the fastest growing market and semiconductor wafer-level packaging is positioned as a strategic growth vertical. No outside funding, revenue, ownership, or M&A activity is disclosed.
