It is featured as simple installation, strong commonality, rich functionality, ease of use. Features: Easy Connection: Eyepiece interface (adapter), designed for the microscope. The under mouth is the 23.2mm, 30mm and 30.5mm or 31.7mm straight inserted, can be installed directly in the biological or stereo eyepiece camera. Computer Imaging Capture & Video Recording: Captures still imagings and live video on your computer. The user-friendly software for Wins offers rich features including Stitching, EDF (Extended Depth of Focus) and video recording. Live video and still imaging capture can be set in different resolutions simultaneously. Multiple Measurements: Support performs measurements for single, parallel or perpendicular lines and rectangular, elliptical and irregular areas; conducts measurements in microns, millimeters, centimeters, inches, feet, and etc. under any magnification powers with desired tolerances. More Features: Support adding layers, watermarks, mosaics, tiles; adjust color balance, exposure, saturation, contrast, orientation; change resolution, histogram, granulation, diffusion; transform imagings via edges detection, digital imaging warping; adds notes, measurements, text, arrows, labels, and etc. using customizable text with different sizes and colors. Compact Size: The color of the machine body is black with light outlook design. It is designed especially for troubles bothering traditional telescope users. Only by connecting it to traditional telescope can you release your eyes fettered on telescope to alternate traditional telescope into electron telescope immediately. It is featured as simple installation, strong commonality, rich functionality, ease of use. Application Areas: Industrial Vision, Visual Inspection, Microscope, Astronomical Telescope, Intelligent Terminal Equipment, Face Recognition, Advertisement Machine, Vegetable Recognition, Intelligent Vending Camera, Electronic Weighing Object Recognition, USB Raspberry Pi Camera, Code Scanning Camera, and so on.
