Jingfei FLA6000 Fiber Optic Spectrometer (200–1100 nm)

Overview

The Jingfei FLA6000 Fiber Optic Spectrometer is a high-performance, compact benchtop spectrometer engineered for precision UV-VIS-NIR spectral acquisition across a broad 200–1100 nm wavelength range. Based on Czerny-Turner optical architecture with an extended optical path length, the FLA6000 integrates a high-line-density diffraction grating and a precision-machined 30 µm entrance slit to achieve a nominal optical resolution of 0.10 nm FWHM—enabling fine spectral feature discrimination in demanding analytical environments. Its core detector is a Hamamatsu CMOS linear array sensor with 2048 active pixels, delivering high quantum efficiency across the full spectral band, low read noise, and rapid frame rates compatible with real-time process monitoring and kinetic studies. Designed for laboratory, industrial, and OEM integration applications, the FLA6000 operates without active cooling yet maintains thermal stability sufficient for quantitative measurements under ambient conditions.

Key Features

• Extended spectral coverage from deep UV (200 nm) to near-infrared (1100 nm) in a single optical configuration
• Optical resolution of ≤0.10 nm FWHM—validated using mercury-argon emission lines per ISO 17025 traceable procedures
• High dynamic range of 1,000,000:1 (typical), achieved through dual-gain analog front-end and 16-bit digitization
• Stray light suppression <0.1% at 600 nm (measured per ASTM E275-22 using holmium oxide filter method)
• Multi-unit synchronization capability: supports hardware-triggered acquisition across up to 8 units with sub-microsecond timing alignment and spectral data normalization
• Triple interface support: USB 2.0 (plug-and-play, low-latency), RS-232 (legacy system integration), and RS-485 (industrial daisy-chain deployment)
• Robust mechanical design: aluminum alloy housing (157 × 110 × 50 mm, 1150 g) with IP52-rated enclosure for lab and light industrial use

Sample Compatibility & Compliance

The FLA6000 interfaces seamlessly with standard SMA905 fiber-optic probes (e.g., reflection, transmission, or immersion configurations), integrating into flow cells, cuvette holders, or custom optical setups. It supports both absolute irradiance calibration (via NIST-traceable tungsten-halogen and deuterium sources) and relative reflectance/transmittance measurements. The instrument complies with IEC 61326-1:2013 for electromagnetic compatibility and meets CE marking requirements for laboratory instrumentation. While not certified for GMP production environments out-of-the-box, its stable gain calibration, audit-ready firmware logging, and deterministic trigger behavior make it suitable for GLP-compliant spectroscopic validation protocols when paired with appropriate SOPs and calibration documentation.

Software & Data Management

The FLA6000 ships with Jingfei SpectraSuite™ SDK (Windows/Linux/macOS), providing native C/C++, Python (PyFLA), and LabVIEW drivers. Spectral acquisition, baseline correction, peak identification, and multi-curve overlay are supported via GUI or script-driven workflows. Raw spectra are saved in HDF5 format (with embedded metadata: timestamp, integration time, slit ID, calibration coefficients), ensuring FAIR (Findable, Accessible, Interoperable, Reusable) data principles. For regulated environments, optional add-ons include 21 CFR Part 11-compliant user access control, electronic signatures, and immutable audit trails—fully configurable via external authentication servers (LDAP/Active Directory).

Applications

• UV-Vis quantitative analysis of organic dyes, pharmaceutical actives, and water quality parameters (e.g., nitrate, COD estimation)
• NIR-based moisture and protein content measurement in agricultural and food processing lines
• Plasma emission monitoring in semiconductor etch chambers and PVD sputtering systems
• LED and laser diode spectral characterization—including centroid wavelength, FWHM, and side-mode suppression ratio (SMSR)
• Multi-spectral imaging backend for hyperspectral line-scan systems requiring synchronized spectral capture
• OEM integration into portable environmental sensors, handheld colorimeters, and educational spectrophotometers

FAQ

Is the FLA6000 compatible with third-party fiber-optic accessories?
Yes—SMA905-compatible fibers, collimators, and cuvette holders from Ocean Insight, Avantes, and Thorlabs are fully interoperable.
Can resolution be improved beyond 0.10 nm FWHM?
Resolution is fixed by optical design; however, software-based deconvolution (using supplied Richardson-Lucy algorithm module) can enhance effective resolving power for isolated narrow peaks.
Does the spectrometer support dark current subtraction during acquisition?
Yes—hardware-synchronized dark reference capture is triggered automatically before each sample scan when enabled in acquisition settings.
What is the maximum recommended integration time?
Up to 65 seconds; longer durations may introduce thermal drift in CMOS response, which is mitigated by onboard temperature monitoring and optional polynomial correction.
Is factory recalibration required annually?
No mandatory schedule; calibration stability is verified at shipment (±0.05 nm wavelength drift over 12 months at 23 °C ±2 °C), but users may perform user calibration using provided Hg-Ar lamp kit.
