The Veho Discovery DX-3 3.5MP Digital USB Microscope is designed to assist you in your scientific studies and observations in the lab or classroom or out in the field. Its built-in TFT LCD screen, lithium battery, and microSD card slot allow you to do your microscopy untethered in the field with the ability to save your images or video and download them to a computer later. The optical system features a 3.5MP CMOS imaging sensor that allows you to capture still images or video and display and save them on your computer. HDMI and TV output ports let you view your specimen on a TV or free-standing monitor without a computer. An included stand allows you to precisely set the height of the microscope above your specimen, from rocks and gems to slides, stamps, or textile samples.
