Objective selection, illumination intensity, focusing, aperture setting and fluorescent-filter position (up to 8) can be controlled using a separate satellite remote control unit, which can be placed on either side of the DM RXA2 and DM RA2 automated microscopes. The microscopes feature a proximity sensor that detects the approach of the user to the microscope and automatically opens the shutter when the user looks through the eyepiece. When the user moves away, the shutter automatically closes to prevent the specimen from fading.
