整が必要であった。Recently, a microbial monitoring monitor has been proposed in which a waterproof box with a built-in television camera is immersed in wastewater, and the state of microorganisms in wastewater can be directly monitored using the television camera. However, conventional TV cameras have a structure in which the magnification of the lens system cannot be changed automatically, and when changing the magnification, the entire lens system must be replaced. When this magnification is changed, the focal length of the lens system changes, so it is necessary to change the slit of the sample chamber and adjust the light amount each time.
