The system includes an adjustable light source constructed to direct a beam of electromagnetic radiation at a specimen chamber that allows a portion of the beam to scatter when illuminating particles within the chamber. The scattered portion of the beam is directed to a sensor, the sensor having a frame rate and a time period between frames. The system may have a processor connected to the sensor and light source, the processor may perform the following steps: activate the light source and obtain images from sensor; if the images from the sensor show that particles are blinking then reduce the frame rate, set the exposure time to at least 60% of the time between frames and reduce the illumination. Then, the processor obtains additional images and processes those images to mitigate blurring. The processor determines the Brownian motion of the particles from the processed images and determines the sizes of the particles based on the motion.
