Precision Ball Screw Driven Motorized Linear Stage For Optical Microscopy
High precision motorized linear stage: PT-GD140G-150
The electric translation platform is a translation platform driven by electric power. It is generally composed of components such as screw, guide rail, table top, driver, controller, etc. It can accurately control the displacement of the translation platform through software, and can also set the operation program of the translation platform through coding.
Motorized linear stage product characteristics:
1. The guide rail of this electric translation platform adopts a precise linear slider guide rail (square, integrally connected to the bottom plate), which is comfortable in movement and large in load, and is suitable for single axle heavy load or multi axle combined use.
2. The precise grinding of the bottom plate of the electric moving table and the reasonable fixing method of the guide rail greatly reduce the pitch and yaw of the electric moving table, and greatly improve the straightness and parallelism of the movement.
3. Replaceable servo motor, grating ruler for closed-loop control, achieving high speed and heavy load.

Application of motorized linear stage in optics
The motorized linear stage can be used for optical breadboard prototypes, optical calibration and calibration, image acquisition, image analysis, time-resolved optical spectroscopy, laser wavelength tuning, laser beam stabilization, research and application of laser driven electron acceleration, optical crystal positioning, Michelson interferometer, beam analysis, and femtosecond laser pulse characterization in the field of photonics.
With a Michelson interferometer, it is necessary to move the reflective lens to obtain the optimal optical path difference. This process can be easily achieved through an electronically controlled translation table, avoiding the disadvantage of manual movement being not precise and controllable enough.
PDV is deeply involved in the field of precision motion control. Over the years, it has independently designed and produced many electrically controlled displacement tables with independent intellectual property rights, which can meet different applications and can be customized according to different needs.
