Motorized Translation Stage

The knowledge-based company Fath Noor Mihan has equipped its manual linear shifter with this technology by designing and manufacturing a motor module. This motorized displacer has a movement range of 20 mm and an accuracy of better than 2 micrometers, which means that the accuracy of this device has increased more than 5 times compared to its constituent manual linear displacer.

In the research laboratories of physics, optics and precision measuring devices, where it is necessary to sweep a certain length with certain steps with high precision or to measure a large number of data, the use of a manual shifter is not recommended due to the difficulty and occurrence of errors, and a motorized shifter is not recommended. It is a very suitable alternative in this type of measurements. The motor displacement is widely used in devices such as optical microscopes, atomic force microscopes (AFM), interferometers and allograms, optical tweezers, and optical arrangements.

The motor module of this mover includes two mechanical and electronic parts. The mechanical part is a servo motor that consists of a DC motor along with a gearbox, a rotary encoder and a mechanism for converting rotary motion into linear motion. The electronic part includes the power supply of the motor, feedback microcontroller and communication with the computer. Also, the beginning and end of the movement range is defined and limited by optical sensors.

The motor module of the device is equipped with a keyboard, screen and a joystick. By using these features, you can set the shifter in a specific position or manually move the shifter forward and backward. By connecting this device to the computer through the USB port, in addition to viewing data simultaneously on the monitor, it is possible to apply all the settings on a computer using the software designed for the device. Also, the ability to program using different software and programming languages is also provided.
