LEICA / CAMBRIDGE / LEO S-440 is a high-end optical instrument designed for a variety of research and industrial applications. This powerful microscope is capable of magnifications ranging from 10X to 500X, and offers darkfield, brightfield, and phase contrast illumination modes. The microscope features an optically corrected infinity corrected optical system, allowing for enhanced image resolution and clarity. The microscope is ergonomically designed, with the user seated in comfort for extended working hours. It has a motorized stage and automated focus system, allowing for precise scanning across the specimen and focus adjustment at the push of a button. The large stage movement range of $X-Y-Z$ provides for maximum coverage of specimens in a single revolution. LEO S-440 includes a superior optical system involving precision-crafted components such as long working distance Infinity corrected objective lenses, triple-apochromatic (3-lens) correction, and anti-reflection optical coatings. During observation, the microscope's full-surface light path design produces excellent edge-to-edge illumination, and advanced contrast methods such as differential interference contrast (DIC) and modulation contrast (MC) give scientists the ability to observe cellular structures and other subtle details. The microscope also includes digital imaging capabilities, allowing users to share images quickly and efficiently. The camera is coupled to a powerful image processing package, allowing researchers to accurately and effortlessly measure, count, and analyze specimens. Drawings, documentation, raw data, and other annotations can be exported in a variety of formats, providing scientists with useful data not easily accessible through traditional methods. LEICA S-440 has a robust and durable design, making it well-suited for professional and laboratory use. With extra-large workspace, excellent specimen presentation, and unparalleled optical performance, CAMBRIDGE S-440 provides scientists with a powerful tool to achieve the best possible results in their studies.
