ZOLIX GLORIA-T150A/T250A 150W–250W Tungsten-Halogen Broadband Light Source

Overview

The ZOLIX GLORIA-T150A and GLORIA-T250A are high-stability, externally adjustable tungsten-halogen broadband light sources engineered for precision optical laboratory applications requiring continuous-spectrum illumination from the visible to near-infrared (VIS–NIR, ~350–2500 nm). Unlike pulsed or narrowband sources, these instruments deliver thermally stabilized, spatially uniform output via a collimated 46 mm diameter beam—ideal for spectroscopic calibration, reflectance/transmittance measurements, ellipsometry alignment, and optical component testing. The core architecture integrates a high-efficiency rear-mounted ellipsoidal reflector that increases radiant flux collection by up to 60% compared to conventional front-reflecting configurations. Each unit employs a digitally regulated constant-current power supply with real-time digital panel readouts for current, voltage, and operational status—ensuring repeatable lamp biasing across experimental sessions and inter-laboratory reproducibility.

Key Features

• Stable broadband emission: Continuous spectral output from 350 nm to >2500 nm, with color temperatures of 3200 K (T150) and 3000 K (T250), optimized for radiometric consistency in VIS–NIR applications.
• Externally adjustable optical axis: Precision-height feet enable vertical beam alignment within a 137–173 mm range; lamp filament positioning is controlled via front-panel knobs without opening the source housing—minimizing contamination risk and thermal drift during setup.
• Dual-model scalability: GLORIA-T150A (150 W, 6.5 A max) and GLORIA-T250A (250 W, 10.8 A max) accommodate varying irradiance demands while maintaining identical mechanical and electrical interfaces for seamless system integration.
• Active thermal management: Integrated axial fan ensures forced-air convection across the lamp envelope and heat sink, maintaining safe operating surface temperatures (<80 °C at housing exterior) despite bulb junction temperatures exceeding 2500 °C.
• High-fidelity current regulation: Constant-current supplies feature closed-loop feedback control using precision shunt sensing, comparator amplification, and dynamic pass-transistor adjustment—achieving ±0.05% long-term current stability under line-voltage fluctuations of ±10%.

Sample Compatibility & Compliance

The GLORIA series is compatible with standard optical breadboards (M6/M4 threaded mounting), spectrometer input slits (via optional fiber couplers or focusing lenses), integrating spheres (e.g., Labsphere ISF-100), and monochromator entrance optics. All units comply with IEC 61000-4-3 (radiated immunity) and IEC 61000-4-4 (electrical fast transient immunity) for laboratory electromagnetic environments. Lamp operation adheres to IEC 60432-2 safety standards for tungsten-halogen lamps, including mandatory thermal warning labels and mechanical shielding per EN 62471 (Photobiological Safety of Lamps). The power supplies meet UL/CSA 61010-1 requirements for laboratory electrical equipment. No hazardous substances are used per RoHS Directive 2011/65/EU.

Software & Data Management

While the GLORIA-T150A/T250A operate as standalone analog sources, they support full traceability and audit-ready documentation when integrated into automated test platforms. Optional RS-232 or USB-to-serial adapters enable remote current/voltage setpoint control and real-time telemetry logging via third-party software (e.g., LabVIEW, Python pySerial, MATLAB Instrument Control Toolbox). All power supply parameters—including ramp rate, hold time, and overcurrent trip thresholds—can be scripted and stored in configuration files compliant with ISO/IEC 17025 documentation requirements. For GLP/GMP-regulated environments, users may implement electronic logbooks with timestamped parameter records aligned with FDA 21 CFR Part 11 principles (electronic signatures, audit trails, and data integrity controls).

Applications

• Calibration of VIS–NIR spectroradiometers and hyperspectral imagers against NIST-traceable standards.
• Diffuse reflectance and transmittance measurements of thin films, coatings, and biological tissues using integrating sphere setups.
• Alignment and verification of optical paths in FTIR, Raman, and photoluminescence systems requiring stable background illumination.
• Accelerated aging tests of photovoltaic materials under controlled broadband irradiance (IEC 61215 compliance support).
• Development and validation of machine vision lighting protocols for industrial inspection systems operating in 400–1000 nm bands.

FAQ

What is the recommended warm-up time before achieving spectral stability?
Allow 15–20 minutes after ignition for filament temperature stabilization; spectral radiance variation remains within ±0.3% after this period.
Can the GLORIA source be operated continuously for extended durations?
Yes—rated for uninterrupted operation up to 2000 hours per lamp; however, periodic lamp replacement is required per manufacturer specifications to maintain radiometric fidelity.
Is fiber coupling supported out-of-the-box?
No native fiber port is included, but SMA905 or FC/PC-compatible collimator adapters (e.g., ZOLIX FCA-46) are available as optional accessories.
How is thermal safety enforced during operation?
The housing incorporates dual thermal cutoff switches (120 °C and 150 °C thresholds) that interrupt power if internal airflow is obstructed or ambient temperature exceeds 40 °C.
Are replacement lamps supplied with calibrated spectral data sheets?
Each LSB-T150 and LSB-T250 lamp ships with individual spectral irradiance curves measured on a NIST-calibrated double-monochromator system, traceable to SRM 2030 and SRM 2031.
