Abstract
A method, and a calibration device, for calibrating a system for analyzing aqueous solutions and that includes a pixel array and a variable focus line for focusing onto the pixel array illuminated images of the aqueous solutions. The method includes the steps of illuminating a pattern on the calibration device to form an illuminated image of that pattern, and directing that illuminated image through the lens and onto the pixel array. The method includes the further step of deriving data values representing the image on the pixel array, and using those data values to adjust the focus of the lens and to adjust the position of the calibration device relative to the pixel array.
