KSMR Series High-Precision Manual Rotary Stage

Overview

The KSMR Series High-Precision Manual Rotary Stage is an engineered solution for demanding optical alignment, interferometry setup, polarization control, and beam steering applications requiring sub-arcminute angular repeatability and minimal axial runout. Built upon a kinematically stable architecture, the stage employs crossed-roller bearing rings—precision-ground and preloaded—to constrain radial, axial, and tilting degrees of freedom while enabling smooth, hysteresis-free rotation. Unlike conventional ball-bearing stages, the crossed-roller design delivers superior motion fidelity, with total indicator runout (TIR) maintained below 30 µm across full 360° travel. The dual-range adjustment system integrates coarse 360° unlimited rotation with fine-tuning capability over ±5°, actuated via a calibrated micrometer head featuring a 5-arcminute vernier scale and 4-arcsecond theoretical resolution—enabling deterministic angular placement in both laboratory prototyping and metrology-grade instrument integration.

Key Features

• Crossed-roller bearing ring assembly ensures high rigidity, low wobble, and exceptional repeatability—meeting ISO 9283 positional accuracy benchmarks for manual rotational stages.
• Dual-mode angular control: full 360° coarse rotation coupled with ±5° fine adjustment via precision micrometer drive, optimized for iterative alignment workflows.
• Aerospace-grade aluminum alloy body provides optimal stiffness-to-weight ratio, thermal stability, and compatibility with vacuum-compatible surface treatments (e.g., hard anodizing).
• Modular mechanical interface: standardized M6 mounting patterns on both base and top plate conform to ANSI/B46.1 surface finish specifications, enabling direct integration with ZOLIX’s KSMx-series linear, tilt, and height-adjustment stages.
• Configurable optical access: models available with or without central through-hole (diameter matched to standard optical post mounts), supporting collimated beam passage and coaxial sensor alignment.
• Load-rated for ≤10 kg centered horizontal load—validated under static and quasi-static conditions per ASTM E2920 calibration protocol.

Sample Compatibility & Compliance

The KSMR stage is compatible with standard Ø25.4 mm and Ø50.8 mm optical components including waveplates, polarizers, mirrors, and fiber collimators. Its low-profile geometry (typical height <35 mm) supports compact multi-axis optical benches and folded-path interferometers. All units undergo factory verification of axial runout, eccentricity, and angular hysteresis using laser autocollimation and capacitive displacement sensors traceable to NIM (National Institute of Metrology, China). Design documentation includes compliance statements referencing ISO 9283 (robotic positioning performance), ASTM E2920 (angular device calibration), and general GLP-aligned test records suitable for internal QA audits.

Software & Data Management

As a purely manual, non-motorized stage, the KSMR Series requires no firmware, drivers, or software integration. Angular positions are recorded manually using the engraved vernier scale and micrometer dial; users may log readings into LIMS or ELN platforms via standardized templates (e.g., CSV export from lab notebooks). For traceability-critical environments—including ISO/IEC 17025-accredited labs—the micrometer head is supplied with individual calibration certificates (NIST-traceable reference standards), and each unit bears a unique serial number linked to its as-tested runout and sensitivity data.

Applications

• Laser cavity alignment and resonator mode optimization
• Polarization state control in ellipsometry and Mueller matrix measurements
• Angle-resolved reflectance/transmittance spectroscopy setups
• Multi-axis goniometer integration for crystallographic sample orientation
• Reference-standard calibration of automated rotary encoders and servo stages
• Education and training rigs for optical engineering laboratories

FAQ

Is the KSMR stage compatible with vacuum environments?
Yes—when specified with hard-anodized surface treatment and stainless steel fasteners, the KSMR series meets UHV-compatible outgassing requirements per ASTM E595; consult ZOLIX Application Engineering for material certification packages.
Can I mount a motorized actuator to the KSMR stage?
The stage is not designed for direct motor coupling; however, third-party piezo-driven or stepper-motor adapters (e.g., Thorlabs KDC101-compatible brackets) may be mechanically interfaced using custom mounting plates—ZOLIX provides dimensional drawings and torque specs for such integrations.
What is the typical lead time for custom configurations (e.g., non-standard aperture or metric thread variants)?
Standard models ship within 10 business days; custom configurations require 3–4 weeks for mechanical validation and calibration reporting.
Does ZOLIX provide recalibration services?
Yes—ZOLIX offers biannual recalibration services at its Beijing metrology lab, including TIR measurement, angular error mapping, and updated NIST-traceable certificates compliant with ISO/IEC 17025.
Are mounting hardware and alignment tools included?
Each unit ships with M6 cap screws, leveling feet (optional), and a calibration certificate; alignment tools (e.g., autocollimator targets, digital inclinometers) are available separately under ZOLIX accessory catalog Z-ACC-ROT-01.
