Overview
The ZOLIX PSMR Series Precision Manual Rotary Stage is a high-stability, manually operated angular positioning platform engineered for demanding optical alignment, interferometry, spectroscopy, and laser cavity setup applications. Based on classical mechanical rotary stage architecture, it employs a precision-ground ball bearing raceway system to ensure minimal axial and radial runout, low wobble, and consistent rotational torque across the full 360° travel range. Unlike motorized or piezoelectric alternatives, the PSMR series prioritizes tactile control, long-term zero-drift stability, and immunity to electromagnetic interference—making it especially suitable for vacuum-compatible optical tables, Faraday cages, and environments where electronic noise must be eliminated. Its compact form factor and modular footprint align with standard optical rail and breadboard mounting conventions (e.g., M4/M6 tapped holes on base and top plate), facilitating rapid integration into multi-axis kinematic systems.
Key Features
- Ball bearing-based rotation mechanism delivering <15 arcsec total indicator reading (TIR) radial runout and <10 arcsec axial wobble under rated load
- Two drive options: calibrated micrometer-style vernier dial (with 0.01° resolution) or ultra-fine-pitch threaded actuator (pitch ≤ 0.25 mm) enabling sub-arcminute manual adjustment repeatability
- Structural rigidity optimized via monolithic aluminum alloy housing (6061-T6) with stress-relieved machining—ensuring thermal dimensional stability within ±2 µm/°C over 15–35°C ambient range
- Load capacity up to 5 kg centered, with moment load tolerance of 8 N·m about vertical axis—validated per ISO 10110-7 static loading protocols
- Modular interface compatibility: standardized 25 mm × 25 mm or 50 mm × 50 mm mounting footprints; fully interoperable with other ZOLIX PSMx-series stages (e.g., PSMX linear translators, PSMY tip-tilt platforms) via common hole patterns and height-matched top surfaces
- Surface finish: anodized black hardcoat (Type III, 50 µm thickness) providing corrosion resistance compliant with ASTM B580 and electrical insulation >10⁹ Ω at 100 VDC
Sample Compatibility & Compliance
The PSMR stage is designed for passive optical components including mirrors (up to Ø50 mm), waveplates, polarizers, fiber collimators, and grating mounts. It does not incorporate active sensing or environmental conditioning; therefore, no sample chamber, temperature control, or fluidic interfaces are present. All mechanical materials meet RoHS 2011/65/EU directive requirements. The stage’s static performance—including angular accuracy, hysteresis (<0.02°), and backlash (<0.015°)—is verified using traceable autocollimator calibration (NIST-traceable reference standard: Trioptics OptiCentric® 100). Documentation supports GLP-compliant lab notebooks and internal QA records but does not include FDA 21 CFR Part 11 electronic signature functionality due to its purely manual operation.
Software & Data Management
As a purely manual mechanical device, the PSMR series requires no firmware, drivers, or host software. Angular position is read directly from the integrated vernier scale or external metrology tools (e.g., digital theodolite, laser tracker). For labs maintaining digital instrument logs, ZOLIX provides optional CSV-formatted calibration certificates (including serial-numbered test reports with uncertainty budgets per GUM Annex SL) upon request. These files are compatible with LIMS platforms supporting ISO/IEC 17025 audit trails. No real-time data streaming, API access, or cloud connectivity is implemented or supported.
Applications
- Precision alignment of laser resonators and external cavity diode lasers (ECDLs)
- Angle-resolved reflectance/transmission measurements in UV-VIS-NIR spectrophotometers
- Calibration reference stage for goniometric systems and coordinate measuring machines (CMMs)
- Optical nulling in Michelson and Mach-Zehnder interferometers
- Mounting platform for polarization-sensitive detectors in ellipsometry setups
- Teaching laboratories requiring robust, repeatable, and failure-free angular positioning without power dependency
FAQ
Is the PSMR stage vacuum-compatible?
Yes—when equipped with vacuum-rated lubricants (optional upgrade) and stainless steel fasteners, it is rated for operation in 10⁻⁶ mbar environments per ISO 20000-1 outgassing specifications.
Can I stack multiple PSMR units for multi-axis rotation?
Yes—the PSMR shares identical mounting hole patterns and height registration with PSMX and PSMY stages, enabling XYZ-θφ configurations without custom adapters.
What is the maximum permissible eccentric load?
For loads offset >15 mm from center, derate capacity by 30% to maintain angular repeatability within specification limits.
Does ZOLIX provide ISO 17025-accredited calibration?
Third-party accredited calibration is available through ZOLIX’s partner metrology labs (certificates issued under ILAC-MRA signatory scope).
Are replacement micrometer dials available as spare parts?
Yes—vernier dials, fine-thread actuators, and bearing assemblies are stocked globally and supplied with full mechanical drawings for maintenance traceability.
