Figure 3-1 Perspective View of Sensor Unit with Reflectance Port
During initial power up of the Spectrophotometer, the paddle will
block the Reflectance Port so that the bright illumination from the
Lamp will not be shining into the operator’s eyes. It will stay in this
position until sampling is performed. The mechanism also controls
the illumination time of specimens so that it is illuminated for the
duration of the measurement cycle ( ~ 0.25 sec), and thus minimizes
photochromic effects.
