OPERATIONTo achieve the optimum results from the Hawk Measuring System, the illumination and optics need to be adjusted to
provide the best possible image to the operator. Certain lighting options are better for some applications than others.
Illumination and focus should be adjusted until the image is clear and bright, with good contrast. Maximum contrast
gives the best image resolution and allows for the highest level of accuracy and repeatability.
Contact the nearest Vision Engineering branch/distributor for further advice.
Objective lens
Iris control
Each Macro objective lens has an adjustable iris which restricts the aperture of the lens. By rotating the control ring
on the bottom of the objective lens, the iris opens and closes. Adjusting the objective lens aperture slightly increases
or decreases the depth of field. This feature is useful for subjects where greater surface definition is required. The
same results can be achieved with a Micro objective lens by adjusting the iris wheel in the Episcopic illuminator.
Closing the Substage Iris improves ability to locate an edge on a cylindrical component/raised profile.
