Abstract

A Kodak model 101 sensitometer has been improved from the original design and is now able to follow A. N.S.I, standards for exposure of almost all sensitized products. Improvements made on the machine include the addition of an electromagnetic actuated shutter that is timed by an accurate integrated circuit timer that has the capability of six exposure times ranging from 1/100 sec. to 1 sec. This replaces a sector shutter that was motor driven and timed by a mechanical method. Simplicity of use has been maintained since the only new controls are a set of pushbutton switches to select the exposure time. The shutter system was found to perform with a +/-2% repeatability that is well within A. N.S.I, standards.
