Choosing a Microscope for Nature Study
Microscopes are not essential for nature study. But, they can be useful by magnifying objects beyond the capability of a hand lens.
They come in two basic types: low power and high power. The more magnification the less the object you can see.
Lower Power Models
- range in magnification from 10x and 80x
- good for viewing larger, 3-D objects
- good for viewing insects, insects wings, sand grains, plantparts & rocks, etc.
- often called "stereo" models
- comes in dual power or zoom
- zoom models had a continuously magnifying range often from10x to 40x
- does not need slides, just place object on viewingstage
Higher Power Models
- magnification up to 1000x
- 400x is sufficient for most viewing
- good for viewing very small objects
- view pond water, insects legs, water organisms, slices ofplant stems, cells
- often called a "compound" model
- must use slides to view specimens
In choosing a model for nature study, first decide what you will be viewing. For most naturalists, a lower power, "stereo" model will work well. A magnification that extends beyond your hand lens power is a good place to start. If your hand lens is 14x, then 20x magnification is good.
I have never used a toy plastic model that was satisfactory. Except for the very low powered bug viewers for kids. These actually work well with 4x-6x magnification.
If you are the person you are buying for is a serious naturalist, try a decent stereo model, even a student model. The professional models can be very expensive. If you can, ask science teachers and other naturalists for suggestions.
Unless there is a store that carries microscopes you can test, you may have to order a model, try it out and return it if it is unsatisfactory.
Good places to buy either model are Carolina Biological Supply, Ward's or Fisher Scientific.
The top of the line professional models are made by Carl Zeiss, Leica, Nikon and Olympus. Various other suppliers produce amateur and student models. The suppliers mentioned above will have serviceable brands.
