Model 420-1105-10
The convenience and versatility of viewing a large picture
at 10x magnification, then zooming continuously all the way
to close-up detail at 40x magnification. Upright, unreversed
3-dimensional image remains in focus throughout zoom range.
Optional eyepieces and auxiliary objectives expand magnification
range and working distances.
Universal stand features heavy construction and counterbalanced
arm for maximum stability. With an adjustable mounting post,
it provides extreme flexibility in positioning.

- Achromatic, color corrected lenses.
- Continuous magnification from 10x thru 40x. See specification
chart for full magnification range available with use of
optional auxiliary lenses
FOCUSING
