Abstract

Microscopic examination of corrosion test coupons is a commonly practiced means to evaluate the effectiveness of a corrosion protection program. Often corrosion test coupons are cylindrical in shape. This makes surveying and mapping the coupon surface or placing a point of interest on a coupon directly in the focal point of the imaging system difficult. Most microscopes can be fitted with an imaging stage that moves in the xy direction. This is not sufficient for imaging cylindrical specimens. For cylindrical specimens a rotational motion is needed in conjunction with the xy motion in order to precicely control the location and orientation of the specimen. To overcome this, an apparatus has been designed and mounted to an optical imaging microcrope for the purpose of imaging cylindrical specimens. The apparatus consists of a stepper motor with stepper motor controller. With this device the imaging of cylindrical coupons is quite simple and practical.
