Request InfoCrystal IS Inc.Fabricated using a proprietary boule growth process, Crystal IS Inc.'s single-crystal native aluminum-nitride substrates can be produced with most customer-specified crystallographic orientations while retaining dislocation densities of <1000 cm-2. The 12-mm-diameter substrates exhibit high electrical resistivity and thermal conductivity and have well-defined cleavage planes. The company says that 50-mm-diameter substrates will be available soon.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/10/2023Crystal IS UV-C LEDAsahi Kasei and subsidiary Crystal IS’ Klaran single-chip 160 mW UVC LED is designed to meet the performance and cost targets needed to expand into new applications in high-flow water and air...WEBINARSPhotonics.com 10/27/2021Fiber Optic Solutions for Medical DevicesSteve Allen provides a brief overview and examples of procedures that continue to push adoption and proliferation of optical fiber-based medical devices.
