Overview
The PerfectLight PLS-SME300E H1 Xenon Light Source is a high-stability, externally irradiating broadband light source engineered for precision photochemical and photophysical experimentation. It employs a 300 W short-arc xenon lamp operating under controlled DC current or closed-loop optical feedback, delivering continuous spectral output from the deep UV (320 nm) through the visible spectrum and into the near-infrared (780 nm), with optional extension up to 2500 nm using appropriate optics and detector configurations. Its non-metallic, high-insulation enclosure ensures electrical safety in laboratory environments where grounding constraints or EMI-sensitive instrumentation are present. The compact form factor (W × D × H: 220 × 280 × 180 mm) supports integration into confined reaction chambers, gloveboxes, multi-axis optical benches, and custom-built photoreactor systems—particularly those requiring multi-directional or spatially selective illumination. Designed for reproducible photon flux delivery over extended durations, the PLS-SME300E H1 meets the stringent demands of quantitative photocatalysis, photoelectrochemical (PEC) characterization, quantum yield determination, and accelerated aging studies under standardized irradiance conditions.
Key Features
- Two operational modes: constant-current (electrical control) and constant-irradiance (optical feedback control), enabling both power stability and photometric repeatability across experimental campaigns.
- Digital microprocessor-based power management ensures ±0.3% instantaneous power stability and programmable timing functions—including auto-shutdown—to support unattended long-duration experiments.
- Integrated optical feedback system directly monitors real-time irradiance at the sample plane using a calibrated photodiode sensor; closed-loop adjustment maintains setpoint irradiance within ±3% over ≥8 h at nominal output.
- Patented thermal architecture (CN201320740323.5) combines forced-air convection with optimized heat-path geometry to sustain lamp wall temperature below critical thresholds, extending electrode life and minimizing spectral drift.
- PC-based control interface via Ethernet-enabled serial port allows remote monitoring of lamp voltage/current, irradiance output, fan RPM, and thermal status—compatible with LabVIEW, Python (PySerial), and MATLAB automation frameworks.
- High-voltage ignition is fully integrated into the lamp housing; no external HV cabling eliminates arcing risk and simplifies system layout compliance with IEC 61010-1 safety standards.
Sample Compatibility & Compliance
The PLS-SME300E H1 is compatible with solid, liquid, and gas-phase photocatalytic reactors—including slurry-based suspension systems, immobilized thin-film configurations, and flow-through gas-phase photoreactors. Its external irradiation design permits direct coupling with PerfectLight’s PLR-RP series photothermal evaluation platforms and PLR-PSTRⅡ reactor systems via lens assemblies or right-angle light guides. Spectral output conforms to ISO 9022-18 (optical instruments—environmental testing) and supports ASTM E2027 (standard practice for calibration of broadband UV radiometers). When configured with solar-spectrum-corrected filters and calibrated irradiance sensors, the system satisfies requirements for simulated AM1.5G illumination per ASTM G173-03 and IEC 60904-9. All electrical subsystems comply with CE marking directives (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU), and firmware implements audit-trail-capable event logging suitable for GLP-compliant laboratories.
Software & Data Management
The included Windows-compatible software provides real-time graphical display of irradiance (mW/cm²), lamp current (A), voltage (V), heatsink temperature (°C), and elapsed runtime. Users may define multi-step irradiation protocols—including ramping, dwell, and cycling sequences—with timestamped data export in CSV format. Communication uses ASCII-based serial protocol over TCP/IP, enabling integration into centralized lab data acquisition systems. Firmware supports firmware-over-the-air (FOTA) updates via secure HTTPS handshake. All parameter changes, emergency shutdowns, and hardware fault events are logged with UTC timestamps and stored in non-volatile memory for traceability—meeting FDA 21 CFR Part 11 requirements when deployed with validated user access controls and electronic signature modules.

FAQ
What is the spectral irradiance distribution of the PLS-SME300E H1 without filters?
The unfiltered output follows the characteristic continuum of a 300 W xenon short-arc lamp, peaking near 800 nm with strong UV emission down to 320 nm and measurable intensity up to ~2500 nm when paired with appropriate quartz-transmissive optics and IR-enhanced detectors.
Can the system maintain stable irradiance during 24-hour continuous operation?
Yes—under constant-irradiance mode and ambient temperatures ≤25°C, the system sustains ≤±3% deviation over 8 h; extended runs require active thermal management of the target chamber to prevent convective interference with beam homogeneity.
Is the optical feedback sensor NIST-traceable?
The factory-calibrated photodiode sensor is traceable to NIST Standard Reference Material (SRM) 2252; full calibration certificates—including uncertainty budgets—are available upon request for ISO/IEC 17025-accredited labs.
Does the unit support TTL-triggered shutter synchronization?
Yes—via optional mechanical shutter module with 5 V TTL input, enabling precise temporal gating synchronized to external detectors or pulsed lasers.
What safety certifications does the PLS-SME300E H1 hold?
It carries CE marking per EN 61000-6-3 (EMC) and EN 61010-1 (safety); UL/CSA certification is available under OEM agreement for North American deployment.
