Overview
The ZOLIX RSM100-W Precision Manual Rotary Stage is a high-stability, manually operated angular positioning platform engineered for demanding optical alignment, interferometry, spectroscopy setup, and laser beam steering applications in research laboratories and industrial metrology environments. Based on a robust worm gear transmission architecture, the stage delivers exceptional backlash-free rotation with fine angular resolution—critical for repeatable optical path length adjustment and polarization state control. Its 100 mm diameter top plate features standardized mounting hole patterns (M4/M6 compatible per ZOLIX’s modular optical bench ecosystem), enabling seamless integration with translation stages, kinematic mounts, lens holders, and other optomechanical components. The engraved circumferential scale provides immediate visual reference for coarse angular orientation, while the micrometer-driven fine adjustment enables sub-arcsecond reproducibility without reliance on electronic feedback or external encoders.
Key Features
- Precision-machined worm gear mechanism ensures zero backlash and high torque transmission, supporting smooth, stable rotation under load up to 15 kg.
- 100 mm diameter aluminum alloy top plate with precision-ground surface (flatness ≤ ±2 µm) and standardized M4 threaded holes on 25 mm grid spacing for universal compatibility with ZOLIX and third-party optical components.
- Integrated 360° circumferential scale with 1° minimum graduation and vernier-assisted reading capability for rapid coarse positioning.
- Micrometer-style fine-adjustment knob calibrated to deliver 0.001° (3.6 arcseconds) incremental resolution—verified via interferometric angular calibration methodology.
- Low-inertia design (stage mass: 0.85 kg) minimizes mechanical drift during thermal equilibration and reduces settling time after manual actuation.
- Black anodized finish provides enhanced corrosion resistance and reduced stray light reflection in sensitive optical paths.
Sample Compatibility & Compliance
The RSM100-W is designed for use with standard optical payloads including mirrors (up to Ø75 mm), waveplates, polarizers, fiber collimators, and miniature spectrometer modules. Its mechanical interface complies with ISO 10110-7 surface quality guidelines for optomechanical mounting surfaces and conforms to GD&T tolerances per ISO 2768-mK for general fabrication. While inherently a manual device without electronic output, its mechanical repeatability (±0.002° over 100 cycles at constant temperature) meets alignment stability requirements specified in ISO 10110-1 for optical component assembly and ASTM E2913-13 for laboratory-grade angular positioning instrumentation. No electrical certification (e.g., CE, UL) applies, as the device contains no powered components.
Software & Data Management
As a purely manual, non-motorized stage, the RSM100-W does not incorporate embedded electronics, firmware, or digital interfaces. Consequently, it requires no driver installation, software license, or data logging infrastructure. Angular position is recorded manually via scale reading or documented through external measurement systems such as autocollimators, digital theodolites, or laser interferometers. For laboratories operating under GLP or GMP frameworks, users may integrate stage settings into standardized alignment logs or electronic lab notebooks (ELNs) using traceable manual entry protocols. Audit trails for positional adjustments are maintained externally per institutional SOPs—no FDA 21 CFR Part 11 compliance burden is introduced by the hardware itself.
Applications
- Alignment of cavity mirrors and output couplers in tunable laser resonators.
- Rotation of birefringent elements (e.g., quarter-wave plates, Rochon prisms) in polarization-sensitive setups.
- Stepwise angular scanning in reflectance/transmittance measurements of thin-film coatings.
- Positioning of photodetectors or fiber inputs in angular-dependent quantum efficiency characterization.
- Integration into multi-axis goniometers for ellipsometry or scatterometry sample stages.
- Calibration reference platform for verifying angular encoder linearity in motorized stages.
FAQ
Is the RSM100-W compatible with vacuum environments?
No—the stage uses standard lubricants and non-vacuum-rated bearings; it is rated for ambient air operation only.
Can I mount a Ø50 mm mirror directly onto the stage?
Yes—the top plate supports direct mounting via M4 screws at standard spacing; recommended fastener torque: 0.5–0.7 N·m to avoid distortion.
What is the maximum allowable off-center load?
For optimal sensitivity and longevity, eccentric loads exceeding 30 mm from center should be limited to ≤5 kg to maintain angular resolution and minimize bearing stress.
Does ZOLIX provide angular calibration certificates?
Calibration reports (traceable to national metrology institutes) are available upon request as an optional service—contact technical support for lead time and documentation scope.
How does temperature affect angular repeatability?
Within 20–25 °C ambient range, thermal expansion-induced drift remains below ±0.0005°/°C; for sub-arcsecond work, active thermal stabilization of the optical table is recommended.
