The PEAK® Brand Microfilm Viewers feature high quality glass optics
with a handle designed for insertion of 35 mm film for easy viewing. The 2-group
3-element lens covers the entire frame of the film by compensating spherical
aberration despite the relatively high magnification. The makes the PEAK Microfilm
viewers ideal for viewing not only microfilm and microfiche, but also other films
such as x-ray film as well. A scale of 30 mm with 1 mm divisions is photoengraved
in the viewer but is positioned in a way that does not obstruct the field of view.
The viewers are also designed from the stand point of minimizing eye fatigue
when working for long periods of time with the viewer.
A very smooth turning precision focusing ring makes for easy focusing of the magnifier.
