PUM Series
Product Introduction
The PUM series USB microscope represents a digital microscope with moderate magnification and convenient operation. The magnification can be continuously adjusted linearly from 10× to 280× (display dependent), making it suitable for observing stamps, coins, insects, plants, small rocks, skin, gems, circuit boards, and other specimens. At high magnifications, it can also be used to observe traditional biological slides.
Furthermore, the built-in 2.0 MP CMOS camera can capture and save images and videos of observed samples to a computer. The microscope's LED illumination ensures clear and bright specimen viewing. The included metal stand (M-SD-HM5) ensures stability and accurate focusing when observing objects at high magnifications, providing practical convenience.
The PUM series portable USB microscope serves as an educational and entertaining tool for both students and adults, making it highly suitable for hobbyists, quality control inspectors, medical professionals, and researchers.
Product Features
- USB-powered portable digital microscope with magnification continuously adjustable from 10× to 280×
- Magnification adjustment achieved by varying the distance between PUM and the observation object
- Single distance corresponds to single magnification
- Magnification knob maintains linear relationship with magnification ratio
- Object distance 110→10mm corresponds to 10×→280× magnification (22" display)
- 5-element multi-coated anti-reflection imaging lens
- Built-in 2-megapixel digital camera for capturing photos and videos
- 8-LED ring illumination
- Uses included Windows software to capture images and videos with built-in measurement menu for specimen measurement
- Computer requirements: CD drive and USB2.0 port. UVC plug-and-play support for Windows 7/8/10/11, Vista, and XP (32/64-bit)
