Abstract
A device for optical investigation of a microscope slide includes a support, and a microscope slide holder fixedly attached to the support. A holder unit is attached to the support with at least one spacer unit. The at least one spacer unit enables relative movement between the holder unit and the support. A line sensor is attached to the holder unit, and includes a plurality of sensors arranged in a row. An illuminating device is provided for illuminating a microscope slide disposed on the microscope slide holder. A lens system is attached to the holder unit, and generates an image on the line sensor of at least a part of the microscope slide. A drive is provided for moving the holder unit substantially vertically relative to the sensors of the line sensor.
