Abstract: An embodiment of a path length calibration system is described that comprises a swing arm coupled to a first surface; a base coupled to a second surface configured to receive the sample; a position sensor system comprising a first component coupled to the swing arm and a second component coupled to the base, wherein the position sensor system is configured to provide an output voltage when the swing arm is in a down position; and a processor configured to calibrate a zero path length using the output voltage.

Abstract: An image analysis system includes a video camera that collects YUV color images of a liquid sample disposed between a capital and a pedestal, the color images being collected while a light source shines light through an optical beam path between the capital and the pedestal, and a processor adapted to i) obtain from the YUV color images a grayscale component image and a light scatter component image, and ii) obtain at least one binary image of the grayscale component image and at least one binary image of the light scatter component image.

Abstract: An apparatus includes a first pedestal surface coupled to i) a swing arm and to ii) a light source. The apparatus further includes a magnet, a base plate, a mechanical stop coupled to the base plate, and a second pedestal surface mechanically coupled to said base plate and configured to receive a liquid sample, said second pedestal surface being coupled to a spectrometer. The apparatus further includes a magnetic flux sensor located between north and south magnetic flux fields of the magnet such that the magnetic flux reaching the sensor while the mechanical stop is in physical contact with the swing arm provides a linear range of output of the magnetic flux sensor, and a processor adapted to calibrate the point for minimum optical path length using a threshold magnetic flux field emitted from the magnet and detected by the magnetic flux sensor.
