Extremely accurate MicroRules are ideally suited for direct measurement of two dimensional parts and axial calibration of Optical Measuring Systems. Normally, this would require extensive set-up and expensive capital equipment.

English/Metric scales on the MicroRule are available with graduations as illustrated:

CONSTRUCTION:
Each MicroRule is provided with the scale patterns etched in very durable, double layer chromium deposited on Photo Quality Select Soda Lime Float Glass, nominal thickness 0.220".

The glass is fully supported by low reflection extruded Aluminum side rails. Plastic end caps protect the glass from damage during normal shop use and allow removal of the magnifier slide(s). 12X or 20X Magnifiers, as appropriate, and a durable molded Carrying Case are included.

An NIST Traceable "Certificate of Accuracy" is included. This meets most requirements for Quality Assurance Registration of ISO-9000. MicroRules may be ordered with full Certified Calibration [.xxxxxx-In -OR- .xxxx-mm] for an OPTIONAL Price Addition and extended delivery time.

FEATURES:

MAGNIFIERS: One (1) or Two (2) 20X Magnifiers on MicroRules with Scale Patterns 0.001”/0.025mm.

One (1) or Two (2) 12X Magnifiers on MicroRules with Scale Patterns 0.002”/0.05mm -OR- 0.005"/0.1mm.

6.00”/152mm Pattern Length MicroRules have One (1) Magnifier.

12.00”/305mm AND LARGER MicroRules have Two (2) Magnifiers.

When used in conjunction with our Precision Metrology Grids, or our Precision Inspection/Layout Grid Boxes, these MicroRules can be used to measure very large two dimensional Parts, Structures and Photoplotted Images.
