Abstract

Optical microscope is used to observe very small object that can not be seen with naked eye. Optical microscope become to be very important tool in various filed from research to industrial field. Beside of observation purpose, optical microscope also widely used as measuring tool.

Development of precision microscopic object measuring tool based on visual sensor is done by adding a camera on ocular lens and driving actuator on the microscope stage. The microscope stage is in precision measured movement, so that larger object can be measured. Microscope stage drive is designed using two stepper motor connected through leadsrew. User interface application was made using Borland Delphi 7. Application converts pixel unit from the camera and step from the motor into micrometer unit.

Test result of measuring tool can measure both objects are objects in the visual area of the camera or larger objects. Range of motion of the microscope table by 50 mm x 40 mm. Actuator of microscope stage has a resolution of 0.2 μm of motion with measured accuracy -0.46% to 0.63%.

Keywords
