Translation Stages
If you’re in the market for linear translation stages, you may be overwhelmed by the number of options available. Since not all translation stages are created equal, choosing a model that offers the right performance, throughput, and budget is important.
Our core strength is collaborating with our clients to understand their unique challenges and configure the right motion solution to fit their unique applications.
Dover Motion’s product catalog includes many types of translation stages utilizing direct drive linear motors or stepper motors. Our stages are optimized for various uses, including precision motion, high speed, and compact size.
About Translation Stages
What is a translation stage?
Translation stages provide precise automated positioning and are typically available as either single axis, an XY stage, or XYZ stages. Translation stages are also commonly referred to as XY stages or XY Tables. Each axis of a translation stage must constrain the six degrees of freedom (X, Y, Z, roll, pitch, and yaw) of the payload to only one, producing translation along a straight line. This is accomplished with a set of linear bearing guideways which are attached to a base structural member that provides a stiff support.
Our stages designed specifically for vertical motion can be viewed on our Z Stages page.
The linear bearing guideways can be implemented in a number of ways, including:
- Ball and crossed roller bearings
- Recirculating bearings
- Cam followers or vee wheels
- Air bearings
How does a translation stage work?
Once the payload has been constrained to a single degree of freedom, the system’s next mission is to actuate the payload and provide precise incremental linear motion along the guideway.
Linear actuator methods include:
- Friction screws with anti-backlash nuts
- Ball screws
- Belt and pulley
- Rack and pinion
- Piezo actuators
- Linear motors
Using a linear motor is generally considered to be optimal for high speed motion systems and is the most precise and repeatable linear motion actuation technology.
A translation stage with a linear motor requires a linear feedback device as well as a servo drive and control to close a position feedback loop. With a high-resolution linear encoder, linear actuators can provide position control down to the nanometer level. A typical application for high precision linear actuators is to control the focus of a microscope objective in a digital imaging system.
Dover Motion's Competitive Advantage
- Precision:
One of the key advantages of Dover Motion’s translation stages is their precision. Our stages are designed to provide ultra-smooth and accurate movement, even in applications that require nanometer-level precision. This level of accuracy is essential for industries such as microscopy and semiconductor manufacturing, where even the slightest deviation can lead to major errors or defects. - Durability:
Another advantage of Dover Motion’s translation stages is their durability. Our stages are built to withstand even the most demanding applications up to 100,000km, with rugged construction and high-quality materials that ensure long-lasting performance. Whether you're using your stage in a laboratory setting or an industrial environment, it will provide reliable and consistent performance for years to come. - Versatility:
Dover Motion’s translation stages are highly versatile, with a range of models and configurations available. Whether you require a single-axis stage or a multi-axis system (please verify), Dover Motion has you covered. We also offer a variety of customization options, allowing you to tailor your stage to your specific application and requirements.
