<p>An imaging optical instrument (Fig. 1) for acquiring images of a sample area is disclosed. The instrument includes a spatial detector (See Fig. 1) with aligned detector elements and a variable filter (See Fig. 1) having filter characteristics that vary in at least one direction and are located in an optical path between the sample area and the spatial detector. An actuator is operatively connected between the variable filter and the spatial detector and is operative to move the variable filter along the direction in which the filter characteristics vary (Fig. 1).</p> |
