CEL-LMP400 Electric Height-Adjustable Optical Platform

Overview

The CEL-LMP400 Electric Height-Adjustable Optical Platform is an engineered mechanical positioning system designed specifically to support precise vertical alignment of light sources and photoreactors in laboratory-scale photocatalytic, photoelectrochemical, and solar simulation setups. Developed by CEAULIGHT (formerly Zhongjiao Jinyuan), this platform implements a synchronized DC motor-driven linear actuator mechanism with integrated position feedback, enabling repeatable, stepless height adjustment across a full 400 mm stroke. Unlike manual or rack-and-pinion alternatives, the CEL-LMP400 eliminates operator-induced positional drift and mechanical hysteresis—critical for maintaining consistent irradiance geometry across variable optical path lengths. Its architecture prioritizes rigidity-to-mass ratio, thermal stability, and electromagnetic compatibility with sensitive optical instrumentation, making it suitable for integration into ISO/IEC 17025-accredited testing environments where reproducibility of illumination conditions must be documented and traceable.

Key Features

• 400 mm total vertical travel range—engineered to accommodate diverse reactor geometries, including top-irradiated slurry reactors, side-illuminated flow cells, and multi-layer photoelectrode stacks.
• Motorized height control with fine-tuning capability (±0.1 mm repeatability under static load), supporting both coarse positioning and sub-millimeter optimization of source-to-sample distance.
• Structural frame fabricated from 6061-T6 anodized aluminum alloy—providing high stiffness, low thermal expansion coefficient (23.6 µm/m·°C), and corrosion resistance in ambient lab environments.
• Reinforced Q235 steel base plate with precision-machined mounting surfaces—ensuring uniform load distribution and minimizing torsional deflection during operation.
• Compact rectangular footprint (200 × 280 mm) optimized for benchtop deployment without compromising lateral stability; center-of-gravity positioned well within base envelope for ≥15° tilt resistance.
• Low-noise, brushless DC actuation system rated for continuous duty at 100 W input power (220 V AC, 50 Hz), compliant with IEC 61000-6-3 emission limits.

Sample Compatibility & Compliance

The CEL-LMP400 is mechanically compatible with all CEAULIGHT light source systems—including Xe, LED, and UV-enhanced lamp housings—as well as third-party photoreactors requiring standardized M6 or 1/4″-20 threaded mounting interfaces. Its load capacity (≤15 kg static, ≤10 kg dynamic) supports typical configurations such as 300 W xenon arc lamps with collimating optics, quartz-jacketed immersion wells, and modular gas-tight reaction chambers. The platform conforms to general-purpose laboratory equipment safety requirements per GB/T 29803–2013 (Chinese national standard for electrical safety of analytical instruments) and incorporates grounding continuity verified per IEC 61010-1. While not certified to UL or CE for standalone sale in EU/US markets, its mechanical and electrical design principles align with ISO/IEC 17025 clause 6.4.2 (equipment suitability) when deployed as part of validated photoreactor test methods.

Software & Data Management

The CEL-LMP400 operates via front-panel push-button controls with LED position indicators and does not include embedded firmware or digital communication protocols (e.g., RS-232, USB, or Ethernet). However, its analog-compatible motor driver accepts external 0–10 V DC position setpoint signals, enabling integration into custom automation frameworks using PLCs or LabVIEW-based control systems. Users may log height settings manually alongside irradiance measurements (e.g., using a calibrated silicon photodiode or spectroradiometer) to satisfy GLP documentation requirements for method validation. No audit trail or electronic record functionality is built-in; therefore, laboratories implementing 21 CFR Part 11 compliance must employ external data acquisition systems with secure user authentication and change-controlled configuration management.

Applications

• Vertical alignment calibration of solar simulators (Class AAA, IEC 60904-9) relative to reference cells or test coupons.
• Dynamic adjustment of incident angle and working distance in heterogeneous photocatalysis kinetics studies (e.g., TiO₂ degradation assays per ISO 10678).
• Height synchronization between multiple light sources in multi-wavelength excitation experiments.
• Stabilized positioning of optical fibers or integrating spheres in quantum yield measurement setups (ASTM E2055).
• Benchtop prototyping of scalable photoelectrochemical water-splitting cells requiring iterative gap optimization.

FAQ

Is the CEL-LMP400 compatible with non-CEAULIGHT light sources?
Yes—mechanical compatibility depends on mounting interface dimensions and mass distribution; users should verify that their light source’s base plate aligns with the platform’s 200 × 280 mm footprint and falls within the 15 kg static load limit.
Does the platform include position feedback or encoder resolution specifications?
No—position indication is visual only (LED bar graph); absolute height must be confirmed externally using calipers or laser displacement sensors for metrologically traceable workflows.
Can the unit be operated continuously for extended periods?
Yes—the motor and gearbox are rated for intermittent and continuous duty cycles at ambient temperatures up to 40 °C, provided ventilation clearance ≥50 mm is maintained around the base housing.
What maintenance is required?
Annual inspection of actuator coupling integrity and lubrication of linear guide rails with ISO VG 32 mineral oil is recommended; no scheduled replacement parts are specified in the operational lifetime.
Is technical documentation available in English?
CEAULIGHT provides bilingual (CN/EN) mechanical drawings, dimensional schematics, and safety instructions upon request through authorized distributors; firmware or API documentation is not applicable.
