    Abstract: An imaging spectrometric instrument is disclosed. This instrument can include an imaging detector and one or more calibration standards having different optical properties. Portions of one or more actuators can move the calibration standards between the imaging detector and a sample. This instrument can use the actuator(s) to acquire an image of a sample and measure light and dark reference calibration values in quick succession at a given wavelength, before the instrument is tuned to another wavelength.

    Abstract: An imaging optical instrument for acquiring images of a sample area is disclosed. The instrument includes a spatial detector with aligned detector elements and a variable filter 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.
