This compact desktop microscope features an integrated 3.5" color LCD screen for viewing objects, and a built-in 5-megapixel digital camera with a high-quality glass lens for capturing detailed photos and videos of your discoveries. This versatile 'scope can run on AC power when you're in the classroom or lab, or pop in the included rechargeable battery for up to two hours of operation in the field. The built-in height-adjustable stand provides a steady work platform anywhere you use it. The supplied 2GB MicroSD card stores your images, and includes pre-loaded sample images that you can view on the LCD screen.

Do even more with your computer

The included, feature-rich Celestron software lets you use your compatible PC or Mac® computer to save images of your subjects, add notes or draw on them, record time-lapse animations, and more. The supplied calibration ruler even allows you to make accurate measurements of your specimens.

Using the LCD screen, the microscope's 4-160X magnification range provides a highly detailed view of bugs, plants, gems, stamps, and coins — just to name a few. Viewing your subjects on a computer monitor can provide up to 200X magnification for an even closer look. The manual focus wheel allows you to zero in on your subjects quickly and easily. And a ring of eight adjustable-brightness LED lights in the base of the 'scope provides smooth, even illumination of your subjects for a clear, revealing view.
