The Miniature 28-Step Optical Indexing Rotary Stage is a compact, integrated-drive rotation table engineered for precision positioning tasks in optical alignment, laboratory automation, and small-scale CNC or robotics setups.
Built around a zero-backlash worm-gear mechanism, it delivers smooth, repeatable rotary motion in a footprint small enough to sit in the palm of your hand making it a practical choice for engineers and integrators who need accurate indexing without the bulk of a full-size rotation stage.
An optical indexing rotary stage is a motorized platform that rotates a mounted payload through precise angular steps, commonly used to align optical components, index parts during inspection, or drive the rotational axis of a small automated system.
This model combines an integrated drive with a high-ratio worm gear to achieve fine angular resolution while keeping backlash to a practical minimum.
Key Benefits and Features
Zero-backlash worm-gear drive for ultra-smooth, repeatable rotation without the play common to lower-cost turntables.
A 64:1 gear ratio combined with a 0.05° angular resolution allows for fine, controlled positioning, while a rotation speed of up to 40°/second keeps cycle times short for indexing and scanning applications.
An 8 mm through-hole (bore) runs through the center of the platform, allowing cabling, optical fibers, or shafts to pass through the axis of rotation rather than around it a detail that matters in compact optical benches and instrumentation housings.
Despite weighing roughly 350 g, the stage supports a load capacity of up to 3 kg, giving it enough carrying capacity for small fixtures, optical mounts, sensors, or lightweight tooling.
Its compact housing (comparable in length to a standard marker pen) makes it suitable for space-constrained enclosures where a full-size rotation stage would not fit.
Typical Use Cases
Optical bench alignment and beam-steering setups; laboratory and metrology fixtures requiring repeatable angular indexing; small-scale CNC or robotics projects needing a compact rotary axis; educational and R&D platforms for motion-control experimentation; inspection and scanning systems where a part must be indexed through multiple fixed angular positions.

Frequently Asked Questions
What does “28-step” refer to on this indexing stage?
It refers to the stage’s stepped angular indexing capability, which combined with the 64:1 worm-gear ratio and 0.05° resolution allows the platform to be driven through precise, repeatable rotational positions for indexing and alignment tasks.
What is the load capacity of this rotary stage?
The stage is rated to carry a payload of up to 3 kg while maintaining smooth, zero-backlash rotation.
Does the stage have a through-hole for cabling or optics?
Yes. An 8 mm through-hole runs through the center of the rotation axis, allowing cables, fiber optics, or a shaft to pass through rather than route around the unit.
Is programming or integration support available?
Yes. A 3D model, programming guidance, and custom integration assistance are available to help incorporate the stage into a larger optical or robotic system.
What variant options are available?
This stage is available in three configuration options (A, B, C). If you are unsure which configuration suits your application, contact us before ordering.
What is the condition of this product?
This is a brand-new unit.
