Question

usb computer microscope​

Answer 1

Answer:

USB microscope is a low-powered digital microscope which connects to a computer, normally via a USB port. They are widely available at low cost for use at home or in commerce. Their cost varies in the range of tens to thousands of dollars. In essence, USB microscopes are a webcam with a high-powered macro lens and generally do not use transmitted light, but rely on incident light from in-built LEDs lights situated next to the lens. The light reflected from the sample then enters the camera lens. However, the camera is usually sensitive enough not to need additional lighting. As the camera attaches directly to the USB port of a computer, eyepieces are not required and the images are shown directly on the monitor.
