Introduction to Precision Measuring Instrument Solutions—Lens Industry Measurements —Mitutoyo Precision Measurement Instruments That
Aspheric Lens

Non-contact 3D Measuring System: HQV-WLI
Allows non-contact 3D surface roughness evaluation of a lenssurface. This system can also evaluate in 2D.
Additionally, being provided with the functions of a vision
measuring machine, geometrical tolerance evaluations such as
diameter and flatness can be made.
(Dual-role system)

Surface Roughness and Contour Measuring
System: CS-H5000CNC
Allows nano-level PV value evaluation of an aspheric lens' contour.
This instrument can also evaluate in 3D.
Additionally, since lens alignment is performed mechanicallyinstead of correction by software, this allows correct alignment
measurement on the lens' optical axis. The installed dimensional
analysis function can also measure the values of distance, angle
and step.

High-accuracy Digital Length Measuring Machine: VL-50
Allows desktop measurement of a lens' thickness. This machine enables
measurement of an easily-deformed, thin-walled lens with a low
measuring force of 0.01 N (minimum).

Support Development and Production of Lenses
Lens Mold (Cavity)

Lens Barrel

Minute Form Measuring System: UMAP

Ultra-high Accuracy CNC CMM: LEGEX
The accuracy of a mold cavity will affect the deviation from theoptical axis on both sides of a lens. Therefore, a mold cavity
needs high machining accuracy.
This CMM can evaluate coordinates, positional deviation,
diameter, circularity, etc., with an accuracy of 0.28 µm.

This measuring system is a contact type using a high aspectratio minute probe stylus (e.g.: ø70 µm, 5 mm) that enables highaccuracy evaluation of the diameter, circularity and coaxiality ofa lens barrel.
An ultra-low measuring force (1 µN minimum) eliminates concern
about possible workpiece deformation and allows measurement
without use of fixtures.

ElectrodeLens Mold (Core)
Ultra-high Accuracy Vision Measuring System: ULTRA QV
The electrode used in the electrical discharge machining process ofa lens molding die needs high machining accuracy with respect to its
position and form. This measuring system can evaluate the coordinates and form of a lens electrode with an accuracy of 0.25 µm.

CNC Roundness/Cylindricity Measuring System: RA-H5200

CMM with External Setup System: STRATO-Apex

The coaxiality of a mold core will affect the deviation from theoptical axis on both sides of a lens. Therefore, this mold needs
a high machining accuracy. This system can evaluate circularity,cylindricity and coaxiality with a rotational accuracy of 20 nm.

The use of this CMM allows external setup for measurementof alignment error between an electrical discharge machining
electrode for forming a plastic lens mold and a workpiece, thereby
improving productivity thanks to increase in machine operating time.
The combination with a robot or stocker enables establishmentof an automation system.
