IRD Glass

IRD Glass is a manufacturer of precision glass, optics, ceramic, sapphire and infrared components. It builds parts to customer prints for OEM customers. The site says the company has supported parts from prototype through high volume production since 1982. Work is coordinated across two Minnesota facilities.

The company handles fabrication, machining, polishing, coating, assembly and inspection. The site says basic coatings are applied in house, while advanced coatings such as AR, high-reflection and HLDT are handled through a network of qualified partners. A dedicated cell carries each part from raw material order through final inspection.

The product lines include custom laser optics, medical components, technical glass, and sapphire and technical ceramics. The site lists items such as cavity reflectors, steering mirrors, beamsplitters, filters, prisms and infrared mirrors and windows.

Markets named on the site include laser OEM, medical equipment, aerospace and defense, and sensors and process control. The site says the company makes parts for a long running sensor program. The company does not design the customer's part but reviews it for manufacturability.

The site lists quality certifications under ISO 9001:2015 and ISO 13485:2016. It says the company is ITAR registered and has 98 percent on-time delivery over the past decade. Inspection work is done on equipment from several makers, including Zygo, Zeiss and Nikon.
