Measuring Magnifier and Optical Comparator, 10x - Model ONS-0102

Precision 10x measuring magnifiers and optical comparators with interchangeable glass measuring reticles for the accurate inspection and measurement of linear dimensions as small as 0.005" or 0.1mm.

When an object is viewed through the magnifier, dimensions may be measured quickly and accurately from the scale that is superimposed on the viewed object by the reticle at the base of the magnifier. Many different styles of reticles are available. For large size images of these reticles, click the link in the 'Reticle Specifications' shown below.

Reticle Specifications:

Reticles are available for measuring linear length in inches or millimeters, hole diameters, radius dimensions, angles, etc..

The reticles are manufactured from glass with the graduations on the outside surface which is in contact with the item being measured. This eliminates any inaccuracies due to parallax errors.

The glass reticles are extremely stable and have sharp and crisp black (or white in some cases) graduations which are accurate and easy to read. One reticle is available with "WHITE"' graduations which is especially useful for measuring dark surfaces such as photographic negatives, etc.. Reticles are secured to the base of the magnifier by a threaded knurled ring and are quick and easy to change.

The following reticles are available for this magnifier:

OPS-0001 - Zero Centered Inch and metric scales. Inches to 0.005" on the top and mm to 0.1mm on the bottom.

OPS-0002 - Zero Centered Metric scale. mm to 0.1mm. Note: Smallest graduation is 0.5mm, except the first mm to the right of zero which is 0.1mm and the second mm to the right of zero which is 0.2mm.

OPS-0005 - Same as OPS-0001 above but with 'WHITE' graduations.

OPS-0022 - Zero Centered 0.1mm. Left to Right Inches to 0.005". 90 degree protractor, radius arcs & hole sizes.

OPS-0025 - Inch Scale Reading Left to Right to 0.005".

OPS-0027 - 0.005" & 0.1mm reading Left to Right.  Holes sizes, line lengths, 90 degree protractor & radius arcs.

OPS-9511 - Metric scale reading from Left to Right in mm to 0.1mm.

General Magnifier Information:

Each magnifier incorporates a coated, color corrected achromatic multiple lens system which provides bright, crisp, clear, color corrected and distortion free viewing.

Easy and smooth focusing of the magnifier is made possible by a high quality helicoid system similar to that used on photographic lenses.

The clear base of the magnifiers admit light from all directions to illuminate the viewed object and a flashlight unit is available for low light areas.

The lens diameter is 20mm (0.787") and the field of view is 33mm (1.300").

Two units are available, a regular magnifier and the same magnifier incorporated into a portable flashlight. On the flashlight magnifier, the actual magnifier is identical to the regular magnifier and easily removes from the flashlight unit for independent use.

The flashlight magnifier requires two 'C' cell batteries (not supplied) and replacement bulbs are readily available.

All units are supplied with a protective lens cap and the regular magnifier includes a leatherette storage and carrying case.
