High-quality custom prisms

These high-quality custom prisms combine our ultraprecise fabrication capabilities with our robust, epoxy-free, bonding technology—Chemically Activated Direct Bonding™ (CADB). Based upon your specifications, we can build prisms from 1x1 mm² in size, and in a wide variety of materials including fused silica, BK7, Zerodur, LaSFN9, optical grade silicon, YAG, MgF₂, ULE, and other optical glasses and crystals. Whether you need 10 or 10,000 pieces, our precision wafer-based processes result in high yields and competitive costs, especially at higher volumes. The high-precision assemblies have been widely used for beam steering, wavelength locking and reference cavities in telecommunications and metrology.
