Ergonomic placement of controls allows for stress free operation, increased efficiency and maximum productivity. Equipped with newly upgraded U. Plan Phase and Brightfield Objectives Infinity Corrected, Brightfield 4X, Phase 10X and Phase 40X objectives. Operating comfort and ease of use are top design priorities. The MT4210EL Series microscopes feature a new computer engineered rigid frame that incorporates low positioned coaxial coarse/fine focus controls and ergonomic stage design for maximum efficiency and comfort while also providing an extremely stable operating platform. The MT4210EL Series offers an outstanding range of features and optical performance with an emphasis on all newly engineered high performance optics based on Meiji Techno's ICOS Optical System (Infinity Corrected Optical System). The new optics, provide exceptionally bright, crisp, images, with good color rendition and superior flat fields of view. A modular design facilitates attachment of a variety of accessories such as CMOS/CCD video cameras, digital still cameras, and 35mm cameras. The MT4210EL Series Microscopes offer crisp, distortion free, high resolution images in multiple modes of operation.
