Request InfoSiskiyou Corp.Siskiyou’s gradient contrast illuminator, mounted in lieu of OEM condenser in infinity-corrected microscopes, provides contrast enhancement such as that achieved by DIC, phase contrast and other contrast-enhancement methods. The IS-GCI is rotated in OEM condenser mount until contrast is maximized. It doesn’t attenuate as much light as typical contrast methods, providing more light and superior contrast for high-magnification contrast imaging. Greater image contrast – at a great price – call Siskiyou.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2024 IssueIndustrial Microscopy LED RingThe Model TR.L1 from Titan Tool Supply, Inc. is a specialized 16-LED ring illuminator designed for industrial microscopy applications, including modular toolscopes.
