Zhongjiaojinyuan Export-Grade Precision Optical Elevating Stage

Overview

The Zhongjiaojinyuan Export-Grade Precision Optical Elevating Stage is a manually operated, high-stability mechanical positioning platform engineered for precise vertical adjustment in optical laboratory environments. Designed to meet international export standards for dimensional accuracy, surface flatness, and long-term mechanical repeatability, this stage serves as a critical mounting and alignment interface between light sources and optical setups—particularly in photochemical reaction systems, spectroscopic instrumentation, and collimated beam path configuration. Its operation relies on a dual-screw micrometer-driven lifting mechanism with fine-pitch brass-on-brass threading, delivering smooth, backlash-free vertical translation without lateral drift or tilt-induced beam deviation. The stage is constructed from anodized aluminum alloy (6061-T6) for dimensional stability across ambient temperature fluctuations (±0.5 °C), while the load-bearing surface features a precision-machined, ground-flat top plate (flatness ≤ ±3 µm over 200 × 200 mm) with standardized M4 and M6 tapped holes for secure optical component integration.

Key Features

• Precision-engineered 200 × 200 mm load platform with ISO 10791-4 compliant flatness specification (≤ ±3 µm)
• Manual micrometer lift mechanism offering 0–50 mm vertical travel range with 10 µm resolution per full turn (0.5 mm pitch)
• Integrated anti-rotation guide rods and linear bushings ensure orthogonal motion fidelity and suppress parasitic yaw/pitch during elevation
• Anodized aluminum housing provides corrosion resistance, non-magnetic operation, and compatibility with cleanroom Class 1000 environments
• Standardized mounting pattern (M4 × 0.7 mm and M6 × 1.0 mm tapped holes, grid spacing 25 mm) enables rapid integration with kinematic mounts, lens holders, and fiber couplers
• Designed for static load capacity up to 15 kg with ≤ 0.8 arcsec angular deviation under maximum rated load

Sample Compatibility & Compliance

The elevating stage is mechanically optimized for direct mounting of Zhongjiaojinyuan’s LFP-series broadband and monochromatic light sources—including the LFP150 (150 × 150 mm footprint) and LFP200 (200 × 200 mm footprint)—without adapter plates. Its structural rigidity and low thermal expansion coefficient (23.6 × 10⁻⁶ /°C) minimize focus drift during extended photolysis experiments or multi-hour spectral acquisition protocols. The device complies with CE marking requirements for mechanical equipment (2006/42/EC), conforms to RoHS Directive 2011/65/EU for hazardous substance restrictions, and meets ISO 9001:2015 certified manufacturing controls. While not an active electronic instrument, its mechanical design supports GLP-compliant documentation workflows through traceable serial-number engraving and factory calibration records (available upon request).

Software & Data Management

This is a purely mechanical positioning stage with no embedded electronics, firmware, or software interface. As such, it requires no driver installation, firmware updates, or cybersecurity configuration. All positional adjustments are performed manually via calibrated micrometer knobs, ensuring deterministic, repeatable settings independent of power supply or network connectivity. For laboratories implementing electronic lab notebooks (ELN) or LIMS integration, users may log stage height settings alongside experimental metadata using standard timestamped entries. No FDA 21 CFR Part 11 compliance is applicable, as no electronic records are generated by the device itself—consistent with ISO/IEC 17025:2017 guidance for passive metrological hardware.

Applications

• Vertical alignment of collimated light sources in UV-Vis-NIR photochemical reactors
• Fine-height tuning of lamp housings relative to integrating spheres or monochromator entrance slits
• Stacking and leveling of multi-layer optical benches in teaching and research laboratories
• Integration into custom-built photocatalytic flow cells where source-to-reactor distance must be varied within ±0.1 mm tolerance
• Support platform for motorized XYZ stages requiring stable base elevation reference
• Calibration fixture for beam height verification in laser safety assessments (IEC 60825-1)

FAQ

Is this stage compatible with vacuum or inert gas environments?
Yes—the anodized aluminum construction and absence of lubricants or elastomeric seals permit safe operation in dry nitrogen-purged enclosures; however, vacuum use below 10⁻² mbar is not recommended due to potential outgassing from thread lubricant residues.
Can the platform be customized with additional tapped holes or metric-thread inserts?
Custom machining (e.g., non-standard hole patterns, stainless steel inserts, or black oxide finish) is available under OEM agreement with minimum order quantity of 20 units.
Does Zhongjiaojinyuan provide calibration certificates with traceability to NIM or NIST?
Factory flatness and travel linearity verification reports are provided with each batch shipment; full NIM-traceable calibration (with uncertainty budget) is available as an optional service at time of order.
What is the maximum allowable torque when adjusting the micrometer knob?
Do not exceed 0.8 N·m; overtightening may deform the brass nut assembly and degrade long-term repeatability.
Is replacement of the micrometer scale dial possible if damaged?
Yes—dial assemblies are field-replaceable using standard M3 fasteners; spare parts kits (including calibrated dials and locking screws) are stocked for international distribution.
