ISTEQ Hyperchromator Tunable Laser-Driven Plasma White Light Source

Overview

The ISTEQ Hyperchromator is a high-throughput, tunable monochromator system engineered for precision spectroscopic applications requiring broadband, stable, and spatially coherent white light emission from the deep ultraviolet (DUV) through the near-infrared (NIR). Unlike conventional arc-lamp-based monochromators, the Hyperchromator leverages a laser-driven plasma point source—specifically optimized for integration with the ISTEQ XWS-30 plasma light engine—to deliver exceptional radiance and spectral continuity. Its optical architecture employs all-reflective, high-f/# mirror optics (f/1.5 standard) to maximize photon collection efficiency without compromising resolution or introducing chromatic aberration. The absence of an input slit eliminates throughput-limiting apertures while maintaining spectrally resolved output via diffraction grating selection and precise motorized wavelength scanning. This design enables rapid, repeatable spectral tuning across 185–2500 nm with sub-nanometer reproducibility—making it suitable for time-resolved measurements, calibration traceability, and multi-modal optical characterization where intensity stability and spectral fidelity are critical.

Key Features

• All-reflective optical path with f/1.5 aperture for maximum light throughput and minimal thermal drift
• No input slit: preserves full source etendue while enabling high-resolution output via selectable gratings
• Integrated mechanical shutter for precise exposure control and dark-reference acquisition
• Motorized wavelength scanning at 40–100 nm/s with ±0.1 nm reproducibility over full range
• Flexible output coupling: SMA/FC-terminated fused silica fibers (100–600 µm core) or free-beam configuration with adjustable slit and collimator options
• Native integration with ISTEQ XWS-30 laser-driven plasma source; optional compatibility with third-party DUV–NIR sources
• USB and RS-232 interfaces with comprehensive Windows GUI; LabVIEW™ drivers provided for automated system integration
• Modular grating turret supporting customizable resolution–throughput trade-offs (1–10 nm FWHM)

Sample Compatibility & Compliance

The Hyperchromator is designed for use in regulated and research-grade optical laboratories where spectral accuracy, long-term stability, and instrument traceability are essential. It complies with ISO/IEC 17025 requirements for calibration infrastructure when operated with NIST-traceable reference standards. While not a medical device, its spectral output stability and repeatability support GLP-compliant absorbance and fluorescence quantification workflows. The system meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). Optional spectral power monitoring enables real-time irradiance normalization—critical for quantitative reflectance, transmittance, and quantum yield measurements under ASTM E308, ISO 11664, and CIE S 014 standards.

Software & Data Management

The Hyperchromator ships with a native Windows application offering intuitive wavelength programming, scan sequencing, shutter synchronization, and real-time intensity monitoring. All instrument parameters—including grating position, slit width (if selected), scan velocity, and dwell time—are logged with timestamps and stored in ASCII-compatible .csv format for post-processing interoperability. LabVIEW™ drivers expose low-level VIs for integration into larger test automation frameworks, including those compliant with FDA 21 CFR Part 11 (with appropriate audit trail and electronic signature configuration). Raw spectral data can be exported directly to MATLAB®, Python (via PyVISA), or Igor Pro for advanced curve fitting, multivariate analysis, or machine-learning–based spectral classification.

Applications

• Absorption, transmission, and fluorescence spectroscopy across material science, pharmaceuticals, and life sciences
• Ellipsometry and scatterometry in semiconductor metrology and thin-film process control
• Confocal and widefield fluorescence microscopy illumination, especially for multi-channel spectral unmixing
• Optical component testing—including filters, coatings, lenses, and photonic crystals—under broadband excitation
• Microfluidic and droplet-based assay platforms requiring wavelength-programmable excitation
• Wafer-level defect inspection and contamination mapping in cleanroom environments
• Calibration of spectroradiometers, hyperspectral imagers, and photodetector responsivity standards

FAQ

What light sources are compatible with the Hyperchromator?
The system is natively optimized for direct coupling to the ISTEQ XWS-30 laser-driven plasma source. Custom adapters may enable integration with other high-radiance DUV–NIR sources upon technical review.
Can the Hyperchromator operate without a fiber output?
Yes—it supports free-beam output with user-adjustable exit slits and interchangeable collimators for spatial mode control.
Is spectral power monitoring included as standard?
No; it is available as an optional add-on module with calibrated silicon or InGaAs photodiode detection.
How is wavelength calibration maintained over time?
Factory calibration uses Hg/Ne spectral lines and is retained via non-volatile memory; users may perform periodic verification using external reference lamps.
Does the system support remote operation in automated production environments?
Yes—via USB/RS-232 and LabVIEW™ drivers, with deterministic command-response timing suitable for inline optical inspection systems.
