This is a digital binocular compound 40X-2500X microscope with a vinyl carrying case. It comes with a built-in 3.0MP USB digital imaging system and a 20W halogen illumination system with variable intensity. The USB digital imaging system captures still microscope images and live video on computer without the hassle of setting up the digital camera. The included software compatible with Windows can also be used to make measurements. You can also view and capture the images on iMac or Macbook with Mac OS. All lenses are made of high quality optical glass. The high resolution image in the field of view is crystal clear and will satisfy the demands of professionals. The digital microscope provides light from beneath the stage and are best for viewing biological specimen that allows light to pass through. This microscopy is good for teaching, demonstration, clinical examination and research purpose. It's also capable to add darkfield condenser or phase contrast condenser, e.g.
