Magnifier glass power and work distance: Select magnifiers with a
power that will allow you to perform your task at a comfortable distance. The higher the power of the magnifier the
shorter the focal range(work distance) and the smaller the field of view. The
high power magnifier may not be the best magnifier for you.

clearer image then a non-lighted magnifier.

of a magnifying lens. The higher diopter will provide higher magnification. Diopter is expressed as "D"
Power: Power is how large an object or print increases as you look through
a lens. Magnifying power is expressed as "X"
Focal Length:
Measurement from the center of the lens

Rules Of Magnification.
- The higher the power of the lens, the closer you must get to
the object being viewed and the smaller the field of view.
- As the power of a lens increases the diameter of the lens decreases.
- Diopter is a term used
to determine the power(magnification}of a lens. The terms are sometimes confused.
