Request InfoElectronic Materials Inc.Optocast 3508 from Electronic Materials Inc. is a UV-cured single-component epoxy system for optical and electronic device assembly. The company says the epoxy contains no fillers or particulates and cures completely upon exposure to ultraviolet light. The company also says it is resistant to moisture and thermal degradation, has low ionic content and outgassing, and low shrinkage after curing. Optocast 3508 is suitable for encapsulating optoelectronic devices such as solid-state lasers, laser optical fiber interconnects and light-emitting diode assemblies.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/6/2023Stochastic Measurement DeviceThe FAME™ 300 from Fractilia LLC provides real-time measurement, detection, and monitoring of stochastic defects, helping high-volume manufacturing facilities identify potential process...Photonics Spectra April 2023 IssueUV-Optimized CMOS CameraThe Hawk Indigo UV-optimized camera from Raptor Photonics Ltd. uses a 2/3-in.
