Celestron Digital Microscope Rocks Digital Screen and 2-Megapixel Camera

A sub-$300 microscope with 3.5-inch digital screen and built-in camera is being launched at CES 2008 next week. Celestron's LCD Digital Microscope has three magnification levels of 4x, 10x and 40x, as well as a 4x digital zoom and a six position color filter wheel. There's 128MB storage memory, plus an SD card slot. Full specs are below.

I'm a pathologist, and spend my working life looking down a microscope. I just wanted to clarify something. Novices always look to maximum magnification as a measure of a microscope's worth. "400x mag, that's it!?" Well, my $15000+ microscope has a maximum mag of 400x, and I rarely need to go beyond 250x to reach a diagnosis. Low power gives you the architecture. High power is only used to examine cellular details, which is fine for tumor grading and cytology work, but not for understanding what's going on. In fact, we teach our residents to stay on low power as much as possible, or they don't see the forest for the trees.

In addition, a typical light microscope rarely has decent resolving power beyond 630x without resorting to oil immersion. You only need oil immersion when studying bacteria.

You should evaluate a microscope based on the quality of the optics (objectives, oculars, the sub-stage condenser assembly etc.), ergonomics, and light source rather than the highest mag objective that's shipped with the body. For a layman, you're much better off getting a dissecting microscope, which has a very low magnification, but can view macroscopic objects (such as your hand) rather than prepared slides (which you won't have access to unless you're affiliated with a histology laboratory).
