6.0 AUTOMATIC LIGHT CONTROL (B-150ALC MODELS)
B-150ALC models have a special function called "Automatic Light Control".
The level of light is adjusted by the microscope in order to maintain the same level as the one the user has
chosen, no matter if the aperture of the diaphgram changes, another objective is inserted, opacity of the
sample changes, etc.
