Compact Design Compatible with High Optical Performance

Greenough Optical System Ray Diagram SZ51/61 have zoom ratios of 5:1 and 6.7:1 (zoom range 0.8x-4x and 0.67x-4.5x) respectively and are affordably priced yet off the highest resolving power in their price range and are available with either 45 or 60 degree inclination angles for observation. Utilizing the Greenough optical design, all zoom bodies incorporate the latest aberration and distortion-free optics that set a new standard in optical quality while maintaining superior operability.The V-shape optical path ensures a slim zoom body - ideal for integration into other equipment or stand alone use.3 Dimensional Viewing The optimum inward angle allows just the right combination of high level flatness and depth of focus for 3D viewing. Even a specimen with significant depth can be brought into focus from top to bottom for faster inspectionObservation Images with High Color Fidelity Superior optical coatings render true color images with fine detail.ESD Measures for Protecting Devices from Static ElectricityThe main unit and major accessories can quickly eliminate static electricity with the use of antistatic materials and coatings. This prevents a specimen under observation from electrostatic damage.
