Reticles for Measuring Inches, Millimeters, Angles, and Radius
Optical Comparator and Magni-Focuser


425
10X Optical Comparator has precision focusing for easy measurements of linear dimensions, angles, radii, and diameters. Lens size is 1 1/2" diameter. Photo-etched reticles are easy to read. Comes in leather case with a number 5 reticle.

Magni-Focuser
With exclusive single, clear-view lens. With no center post the viewing area is increased approximately 20%. Shatter-resistant precision, and optical Magni-lens brings the smallest detail up to a larger, and sharper picture. Comes with adjustable headband which flips up and can be worn over regular glasses.

Individual Reticles
We offer 13 styles of reticles to choose from. Simply unscrew the plastic ring and replace with the desired reticle. To order individual reticles, specify the comparator reference number followed by the reticle number desired. Example 425-7
