200x Digital Magnification and Manual Focus
Ashfly rates this microscope at a maximum magnification of 200x, with an achromatic objective lens and a 30 degree angle of view. That is a useful range for a kids' digital microscope: leaf detail, insect legs and eyes, clothing fibers, carpet, granite and skin texture all come through clearly. An achromatic lens is designed to keep colors from fringing at the edges of what you are looking at, which helps the image stay crisp. Focus is manual, which gives control but also takes practice. Because the microscope is handheld, turning the focus can move the whole unit, and young children may need an adult to help them focus at first, though they can get better at it quickly. The narrow 30 degree angle of view means the area on screen is small, so keeping a subject centered takes a steady hand. Magnification is the one aspect where opinion is mixed rather than positive, so set expectations around bold close-ups of everyday things rather than laboratory-level views of cells.
