This is the microscope with an LCD screen that enhances the traditional eyepiece when examining microscopic subjects. A built-in 2 MP digital camera captures still images or videos and displays objects on the 3 1/2" LCD at 1,600 x 1,200 resolution  The microscope’s three objective lenses provide 40X, 100X, and 400X optical magnification, while the 4X digital zoom allows you to view objects at up to 1,600X their actual size. A colored filter wheel helps block out wavelengths to make objects clearer. The camera’s built-in 128 MB memory can store up to 120 still shots or up to 40 minutes of video at 320 x 240 resolution; an SD card slot allows for memory expansion up to 32 GB. A USB port (cable included) allows you to download content to your computer. The microscope includes five prepared slides (shrimp hatchery, sea salt, yeast, brine shrimp), ten blank slides, scissors, tweezers, and pipettes. 15 1/2" H x 8 3/4" W x 7 1/2" D. (7 lbs.)
