The Handheld Digital Microscope Pro from Celestron is a cost-effective digital microscope designed for students and hobbyists. This USB-powered microscope has a built-in CMOS camera sensor capable of capturing still photos and videos with 5 megapixel resolution. The portable computer-powered design makes this unit at home anywhere a laptop can go. Celestron's Mac/Windows-compatible Micro Capture Pro sofitware allows users to analyze, annotate, manipulate, and save the transmitted images from the digital microscope. An included VGA output cable also allows real-time images to be displayed on a TV or projected in a classroom. The Handheld Digital Microscope Pro includes a height-adjustable stand that adds functionality by accommodating tall specimens. A 20-200x magnification zoom range is suited for almost any specimen, including slides and three-dimensional objects. LED illuminators near the microscope objective provide incident lighting that is dimmable using a switch integrated with the USB cable. The built-in 5MP camera, height-adjustable stand, video output cable, and feature-rich sofitware make the Handheld Digital Microscope Pro a well-equipped entry-level instrument for the field, classroom, or home.
