The colony counter is an instrument that is commonly used to count colonies of bacteria or other microorganisms on a plate containing a gelled growth medium. A fully automated system would essentially consist of collecting images using any one of the digital image capturing devices such as document scanner/charge coupled device digital camera/webcam or video equipment. Colonies can be counted from pictures of plates using software tools. In automated systems, the objects and their backgrounds can be varied widely. Usually, one of the three methods of illumination can be selected to enhance visibility and increase accuracy. These are the following: transmission method, reflection method, and dark field method. The colony counter is used for microbiology applications for fast and accurate counting of bacterial and mould colonies.
