The fully integrated instrument. (A) The instrument weighs 50 kg (two-person lift), has dimensions of 26.6” × 16.5” × 23.1”, and is ruggedized to MIL-STD 810F for transportation vibration and shock. (B) Rendering of the optical train inside the instrument. For excitation, laser light is directed to the galvanometer via the steering mirror assembly. The galvanometer interrogates each of the six separation channels of the S&D biochip, exciting fluorophores bound to the amplified STR fragments. For detection, fluorescence is collected by the objective and directed to the photomultiplier tubes.
