Abstract
Microscope-attachment camera with a system for measuring the brightness of an object detail and with markings for indicating at least the detail metering-field and the image-field of the camera in the observation beam. The metering field-marking (14) and the image field-marking (22) are positioned on two separate plates, the metering field-marking plate being designed as a metering field-stop (14), and the two markings which differ in shape and size (14,22) are simultaneously reflected into the observation beam.
