Request InfoElectronic Materials Inc.Optocast 3415 is a single-component optical adhesive for fixturing and focusing optical components in applications where minimal to no movement is desired. Its maker, Electronic Materials Inc., says that it can be cured with long-wave UV light or with heat, producing almost unmeasurable shrinkage on cure, and that it has a coefficient of thermal expansion of less than 14 ppm/°C that virtually eliminates stress. Optocast 3415 is available in 3-, 5- and 10-cc syringes with a freezer life of more than one year.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/1/2024Optical Polishing AbrasivesThe Microlux Powders from Meller Optics are high purity, petroleum-free alumina abrasive powders for use with all hard and soft optical materials.
