We develop the device for sampling, inspecting, and autofocus stacking photomicrography of marine microorganisms and fossils. Our devices automate the microscopic examinations, including sampling and inspecting of micro-objects and motorized stacking micrography. The device for inspecting and sampling micro-objects is disclosed in this invention, including a three-axis scanning platform, a three-axis mechanical arm as well as two optical microscopes. A targeted micro object can be located through a programmed scanning of the microscope in a designated area, and the targeted object can be a draw and fixed on the opening of a dispensing needle, through the aid of negative pressure generated by an air pump; then exported. The sampling rate is expected to increase more than 30% with an improved product quality by a standardized procedure. Motorized stacking micrography extends back to front sharpness of a photomicrograph and greatly reduce the operation time and errors more than 50%.

Our devices automate the experimental procedures for studying marine microorganisms, including sampling and inspecting objects and auto-stacking photomicrography. A device for inspecting and sampling micro-objects is disclosed in this patent invention. A targeted micro object can be located through a programmed scanning of the microscope in a designated area, and the targeted object can be a draw and fixed on the opening of a dispensing needle, through the aid of negative pressure generated by an air pump; then exported. The sampling rate by more than 30% and product quality will be improved through a standardized procedure. Auto-stacking photomicrographic technique overcomes the limitation of low focal depth of the microscope, and the image of an entire object can be brought into focus.

The device can be applied to industries of the precision processing, automation industry, and robotics, such as micro-automatic dispensing, microinjection, adhesion, and injection of micro-objects, as well as the observation and cleaning on the surface of microstructure.  For academic research, the device can be applied in sorting or photomicrography the planktonic samples, seeds, and metal impurities.
