A number of applications in fields such as metrology, photonics packaging, quality assurance testing, adjustment optics etc can benefit from the use of a precision rotation stage. It can also be combined easily with certain types of micropositioning mini slides. It allows for precision positioning applications along with a highly compact and space saving design. The presence of a worm gear drive in these devices means that you can easily achieve unlimited rotation in forward or backward directions. Despite the freedom of movement, the rotation stage takes up very less space.

In this article, we shall elaborate on the features that make these stages an ideal choice for several applications. Following are some of the main features worth considering:

The presence of servo and stepper motors means that you can achieve your most critical positioning requirements. This is what makes this device highly appealing for OEMs. More importantly, it is a very cost effective solution. Users can expect zero backlash because it features a special gearhead, as well as a miniature motor (it could either be DC or stepper motor).

In addition, the DC motor is more often than not fitted with a high resolution encoder that offers a resolution of more than 2000 counts/revolution. Speeds of up to 20 degrees per second can be achieved in this scenario, enhanced with negligible friction.

Another important aspect is that this precision positioning device allows you to enjoy multi-axis combinations as it can be easily combined or integrated with micro linear stages. You don’t need to employ an adapter plate for this purpose. This feature is especially useful in compact operations, because adding a plat can lead to a parallel increase in the height.

To make this device highly suited for optical applications, manufacturers ensure to add a clear aperture. You can even use a lens adapter along with it so that the precision positioning machine can easily be teamed with optic components like the polarizer.

To easily setup and monitor the rotational stage, the scale ring that is present on the outer edge of the turntable proves exceedingly handy.

You can adjust the travel range of the stage to anywhere between 0 degrees to 330 degrees. Moreover, the presence of non-contact and reference switches gives you the assurance of a longer service life.

To sum it up, this precision positioning device offers you several advantages such as impeccable performance, compact design, zero backlash, negligible friction, and great repeatability. However, it is vital that you make a purchase from a renowned manufacturing firm so as to avail other additional benefits such as a warranty. It would be a prudent decision to select a firm that has enough experience in offering cutting edge micro positioning systems.
