The AF4515T5 is a 1.3 MP Dino-Lite Edge Series microscope that has a magnification range of 700x- 900x and built-in axial lighting. Measurements can be performed in different units (inch/mil/mm/um) and types including straight lines, circles, angles, arches grids and more. AMR displays the current magnification on screen with the included software for Windows or Mac OS. Using the included software the AM4515T5 can detect and display the magnification, and store it with the captured picture automatically, making it especially useful for applications when reading the magnification is not feasible or difficult. AMR increases accuracy by eliminating the process of visually reading the magnification, while keeping the possibility to be additionally calibrated in the included software. LED Control gives you command of the LED on/off toggle options.
