Overview
The KSMG Series High-Precision Manual Angular Translation Stage is an engineered optical positioning solution designed for fine angular adjustment in demanding laboratory and industrial optical alignment applications. Based on Couette-type rotational kinematics constrained by precision-machined arc-shaped V-groove bearings, the stage delivers controlled, backlash-free angular displacement with high mechanical stability and repeatability. Its core architecture integrates a compact worm-gear reduction drive system—optimized for torque transmission efficiency and micro-step resolution—enabling sub-arcminute manual tuning without external power or electronic control. The stage is purpose-built for integration into multi-axis optical benches, interferometric setups, laser cavity alignment systems, and polarization-sensitive experiments where thermal drift, hysteresis, and runout must be minimized.
Key Features
- Arc-shaped V-groove linear bearing geometry ensures uniform load distribution and minimizes radial play during angular rotation.
- Aerospace-grade anodized aluminum alloy body provides optimal stiffness-to-weight ratio, dimensional stability across ambient temperature fluctuations (15–30 °C), and corrosion resistance in cleanroom environments.
- Self-locking worm-gear actuation mechanism offers high mechanical advantage, eliminating unintended drift under static load and enabling precise incremental motion down to 0.02° per full turn of the micrometer knob (calibrated scale).
- Radial runout ≤ 5 µm and axial wobble ≤ 8 µm over full 360° travel—validated per ISO 10110-7 methodology—position the KSMG series among the top-tier domestically manufactured angular stages in China’s optical instrumentation sector.
- Modular mounting interface compliant with standard M4 and M6 tapped holes (per ISO 228/1), facilitating rapid integration with breadboards, cage systems (e.g., Thorlabs 30 mm/60 mm), and custom optomechanical assemblies.
Sample Compatibility & Compliance
The KSMG stage supports optical components up to 150 mm in diameter and 2.5 kg in mass—including mirrors, waveplates, polarizers, and fiber collimators—without compromising angular fidelity. It is compatible with vacuum-compatible variants upon request (non-lubricated assembly, low-outgassing adhesives). While not certified to ISO 9001 or CE as a standalone product, its mechanical design adheres to principles outlined in ISO 10110 (optical element surface quality), ISO 2768 (general tolerances), and JIS B 0401 (geometric dimensioning). All units undergo 100% factory verification of angular repeatability (±0.03° over 10 cycles) and bearing preload consistency prior to shipment.
Software & Data Management
As a purely manual mechanical stage, the KSMG series requires no firmware, drivers, or software interface. Angular position is read directly from the engraved vernier scale (resolution: 0.05°) or via optional digital readout (DRO) add-on kits (sold separately), which output RS-232 or USB TTL signals compatible with LabVIEW™, MATLAB® Data Acquisition Toolbox, and Python-based control frameworks (e.g., PyVISA). Audit trails for calibration records and metrology reports are maintained per internal GLP-aligned documentation protocols, supporting traceability in R&D labs subject to internal QA review.
Applications
- Laser cavity mirror alignment in DPSS and ultrafast oscillator systems
- Polarization state control in ellipsometry and Mueller matrix characterization
- Fine-tuning of grating angles in monochromators and spectroscopic beam paths
- Optical nulling in Michelson and Mach–Zehnder interferometers
- Calibration reference stage for angular encoder validation (e.g., against autocollimators per ISO 230-1)
- Education platforms for undergraduate optics laboratories emphasizing mechanical metrology fundamentals
FAQ
Is the KSMG stage compatible with vacuum environments?
Yes—vacuum-compatible configurations are available with dry-film lubricants, stainless steel fasteners, and outgassing-tested adhesives (specify model suffix “-VAC” at order entry).
What is the maximum permissible load moment about the rotation axis?
The stage maintains specified runout performance up to 0.8 N·m off-axis torque; exceeding this may affect bearing life and angular accuracy.
Can multiple KSMG stages be stacked for multi-degree-of-freedom adjustment?
Yes—standard baseplate flatness (≤3 µm over 100 mm) and orthogonal mounting holes support stable XYθ or XYZθ configurations when used with compatible translation stages.
Does ZOLIX provide NIST-traceable calibration certificates?
Traceable angular calibration (using autocollimator-based measurement per ISO 230-1 Annex D) is available as an optional service, with certificates issued per ISO/IEC 17025 requirements.
Are replacement worm gears or V-groove inserts available as spare parts?
Yes—ZOLIX maintains a full spares inventory including wear-prone components; lead time is typically 2–3 weeks ex-Beijing warehouse.
