Request InfoEngis UK Ltd.En-Sapp polishing slurry from Engis UK Ltd. is designed for C-plane sapphire. The material features an ultimate crystal size of 0.3 to 0.5 μm and can produce high-quality surfaces to 0.2 nm Ra. The product’s high percentage of solids means that it can be diluted with water to reduce processing costs. Its high stock removal rate makes it many times faster than colloidal silica. Its noncrystalizing formulation results in reduced machine downtime and maintenance, increasing efficiency and extending machine life.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jan/Feb 2023 IssueSemiconductor Laser DiodeThe Metal Can PLT5 522FA_P-M12 from ams-OSRAM AG is an off-the-shelf semiconductor laser emitter with a 514-nm wavelength output required by many life science, R&D, and diagnostics applications....Photonics Spectra August 2023 IssueBatch PhotoreactorThe Solstice™ temperature-controlled batch photoreactor from Uniqsis Ltd. is designed for small-scale photochemical reactions.
