Abstract
PURPOSE: To provide the device which is capable of adjusting focus with low voltage without vibrations by mounting the objective lens of the microscope to bimorph type piezoelectric elements and providing a means of detecting the focus position and driving the element and a detecting means for lens movement amount.
CONSTITUTION: The slide glass specimen 1 of the microscope is magnified by an objective lens 2 and is photo split by a beam splitter 6. The split beams form the image on the photo detecting plane of a one-dimensional image sensor 7. The optical density image is converted to an electric signal which is then converted to a focus position detecting signal in an analog signal processing part 8. The focus position is detected in an automatic focus adjustment control part 10. Driving of the objective lens part is accomplished by applying voltage to the bimorph construction comprising affixing together two sheets of piezoelectric elements 3, 4. Although the amount of deflection varies with the applied voltage, the material of an elastic plate 5 and others, the size adjustment of about 10μ may be readily performed through voltage application of ±100V.
