AULTT-P2000 Fiber-Optic Spectrometer

Overview

The AULTT-P2000 is a compact, high-performance fiber-optic spectrometer engineered for precision spectral characterization across the visible spectrum (350–1000 nm). Based on Czerny–Turner optical architecture and equipped with a 2048-pixel linear silicon CCD detector, it delivers high signal-to-noise ratio and excellent wavelength fidelity. Its core measurement principle relies on dispersive spectroscopy: incident light—delivered via standard SMA905 optical fiber—is collimated, diffracted by a ruled 600 lines/mm grating, and focused onto the CCD array. The resulting pixel-to-wavelength mapping enables quantitative intensity vs. wavelength acquisition with ≤0.03 nm optical resolution (FWHM) and sub-0.3 nm wavelength repeatability. Designed for laboratory, educational, and industrial QA/QC environments, the P2000 operates entirely from USB bus power—eliminating external power supplies—and maintains thermal and mechanical stability during extended acquisition sequences.

Key Features

• Optical design optimized for visible-range performance (350–1000 nm), with calibrated response traceable to NIST-traceable standards
• High-resolution spectral acquisition enabled by 30 µm entrance slit and 600 lines/mm holographic grating
• 2048-element linear silicon CCD detector with 16-bit analog-to-digital conversion and low dark-current operation
• Fully USB 2.0–based interface: plug-and-play connectivity, no external power adapter required
• Real-time spectral video capture mode for dynamic process monitoring (e.g., LED aging, reaction kinetics, plasma emission)
• Auto-exposure algorithm that dynamically adjusts integration time to prevent saturation while maximizing SNR
• Modular hardware compatibility: supports interchangeable slits, gratings, and fiber-coupled accessories (e.g., integrating spheres, cuvette holders, collimators)

Sample Compatibility & Compliance

The AULTT-P2000 interfaces seamlessly with a broad range of sample illumination and collection configurations—including deuterium-halogen combo sources, pulsed LEDs, laser diodes, and broadband lamps—via standardized 400 µm or 600 µm core optical fibers (SMA905 termination). It supports absorbance, transmittance, reflectance, and radiance measurements when paired with appropriate reference standards and optical accessories. The system complies with general-purpose instrumentation requirements under ISO/IEC 17025 for calibration traceability and supports GLP-aligned data integrity practices: all spectral acquisitions are timestamped, instrument metadata (grating ID, slit width, integration time) is embedded in raw data files, and software enforces immutable audit trails for critical parameters. While not certified for FDA 21 CFR Part 11 out-of-the-box, its software architecture permits configuration for electronic signature and user-access controls in regulated environments.

Software & Data Management

The bundled spectral analysis software provides native support for Windows 7 through Windows 11 and features a multi-instance architecture capable of synchronizing up to eight AULTT-P2000 units simultaneously. Core modules include wavelength calibration (using Hg/Ne/Ar lamp lines), intensity correction (dark current subtraction, pixel sensitivity normalization), absorbance calculation (via reference + sample scans), CIE chromaticity coordinate computation (x,y and u’v’), and correlated color temperature (CCT) estimation. Data export options include CSV (for Excel-compatible spectral tables), TXT (ASCII columnar format), PDF (publication-ready plots with embedded metadata), and BMP/PNG (raster images of spectra). All raw and processed datasets retain full provenance: instrument serial number, acquisition timestamp, firmware version, and user-defined sample ID fields.

Applications

• LED and OLED spectral characterization: peak wavelength, FWHM, dominant wavelength, color rendering index (CRI), and TM-30 metrics
• UV-Vis absorbance quantification of aqueous and organic solutions using cuvette-based fiber probes
• Thin-film and optical coating evaluation via transmission/reflection spectral profiling
• Educational spectroscopy labs: atomic emission line identification (Hg, Na, He), Beer–Lambert law verification, and spectral calibration exercises
• Process monitoring in photobioreactors, UV curing systems, and solar simulator validation
• Quality assurance of lighting products against IES LM-79 and CIE S 025/E:2015 compliance criteria

FAQ

Does the AULTT-P2000 support NIST-traceable wavelength calibration?
Yes—factory calibration uses mercury-argon spectral lines; users may perform secondary calibration using optional Hg/Ne pen-lamp sources.
Can the spectrometer operate in low-light conditions such as fluorescence or Raman applications?
It is optimized for moderate-intensity broadband sources; for ultra-low-light work, a cooled CCD or back-illuminated sensor variant is recommended.
Is the software compatible with LabVIEW or Python for custom automation?
Yes—DLL and Python API (PyAULTT) are provided for programmatic control, spectral acquisition triggering, and real-time data streaming.
What is the maximum acquisition rate in fast-scan mode?
Up to 100 full-spectrum reads per second (at reduced resolution settings); typical high-resolution mode achieves 10–20 Hz with full 2048-pixel readout.
Are firmware updates and software patches available post-purchase?
Yes—AULTT provides free lifetime firmware and software updates via secure customer portal access with registered serial number verification.
