(3) Bringing the measurement point to the apex
If you look into the centering telescope on the left side of the main unit, you will see in the
field of view an image like the one shown in Figure 4. To get a better view of the image,
adjust its size by turning the diaper movement knob. Use the stage movement mechanism to
bring the image into the center of the field of view.
Note: If you do not see any image, it is likely that the lens under inspection is far from the
optical axis of the main unit. In this case, directly observe the lens under inspection and
move it so that its apex comes onto the optical axis of this device.
(4) Once again, look into the eyepiece on the right side of the main unit and focus on the surface
of the objective lens. (For more information, see the Software Operation Manual.)
(5) Follow the instructions in the Software Operation Manual to carry out measurements.
