This is a digital biological trinocular compound microscope that includes a digital imaging system. The digital microscopy comes with a 45° inclined 360° swiveling trinocular sliding viewing head, two pairs of widefield eyepieces, four achromatic objectives, stain-resistant double layer mechanical stage with scales, coarse & fine focusing, NA 1.25 Abbe condenser and variable intensity LED transmitted illumination system. It offers eight levels of magnification power: 40X-80X-100X-200X-400X-800X-1000X-2000X. The USB digital imaging system that captures microscope images and live video on computer. The included software compatible with Windows XP/Vista/7/8/10 can be used to make measurements, You can view and capture the images on iMac or Macbook with Mac OS too. It is easy to mount a darkfield condenser to switch a brightfield microscope to a darkfield microscope. This type of digital compound microscopy is perfect for teaching demonstration and clinical examination, laboratories and advanced applications.
