This is a digital LED trinocular compound microscope that includes a digital imaging system. The trinocular 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 six levels of magnification power: 40X-100X-250X-400X-1000X-2500X. The digital camera captures still images, streams live videos on your computers, and is compatible with Windows (see version information below).The user-friendly editing and processing software for Windows offers advanced features including stitching, EDF (Extended Depth of Focus), video recording and measurement functions. The software allows you to make notes, shapes, and watermarks with ease. You can analyze, present, and share images of samples and specimens using the software. This type of digital compound microscopy is perfect for teaching demonstration and clinical examination, laboratories and advanced applications.
