Overview
The Jingfei FLA4000 Flash-Triggered Fiber Optic Spectrometer is a compact, high-performance benchtop spectrometer engineered for precision UV-VIS-NIR spectral acquisition in demanding laboratory and industrial environments. Based on a symmetrical crossed Czerny-Turner optical design (f/4, 101.6 mm focal length per arm), the FLA4000 delivers stable, low-aberration dispersion across its full 200–1100 nm spectral range. Its flash-triggered acquisition architecture enables precise synchronization with pulsed light sources—such as xenon flash lamps, laser-induced plasmas, or time-gated LEDs—making it especially suitable for transient emission analysis, fluorescence lifetime screening, and time-resolved reflectance measurements. The instrument integrates a high-speed 16-bit analog-to-digital converter with on-board electronic dark current correction, a 4K-deep FIFO buffer, and USB 2.0 (480 Mbps) interface for real-time data streaming. All calibration coefficients—including wavelength, intensity, and nonlinearity corrections—are permanently stored in on-device EEPROM, ensuring traceable, reproducible measurements without host-side recalibration.
Key Features
- Flash-triggered acquisition mode with hardware-level external TTL trigger input (rising-edge sensitive), supporting precise temporal alignment with pulsed excitation sources
- CMOS linear array detector with 2048 pixels, deep-well capacity (~100,000 electrons), and integrated thermoelectric stabilization for reduced dark drift
- Optical resolution of 0.8 nm FWHM (typical, dependent on grating and slit selection); optional configurations support sub-0.5 nm resolution via custom 30 µm slit and high-line-density gratings
- Ultra-low stray light (<0.1% at 600 nm), achieved through optimized baffling, multi-coated mirrors, and black-anodized internal surfaces
- Programmable integration time from 1 ms to 60 s, with electronic shutter control to prevent saturation during high-intensity flash events
- On-board 16-bit A/D with auto-zero function and RMS dark noise ≤12 counts, enabling high-fidelity low-light signal capture
- Compact form factor (125 × 70 × 40 mm, 690 g) with SMA905 fiber coupling and robust aluminum housing for vibration-resistant field deployment
Sample Compatibility & Compliance
The FLA4000 is compatible with standard 200–2200 µm core multimode silica fibers and supports modular optical accessories—including cuvette holders, integrating spheres, collimating lenses, and reflection probes—enabling flexible configuration for absorbance, transmittance, reflectance, and emission measurements. It meets mechanical and electromagnetic compatibility requirements per IEC 61326-1:2013 (industrial environment) and conforms to RoHS Directive 2011/65/EU. While not certified for GMP or FDA 21 CFR Part 11 out-of-the-box, the device supports audit-trail-capable software integration via SDK (C/C++, Python, LabVIEW), allowing users to implement electronic signature, user access control, and raw-data integrity protocols required under GLP and ISO/IEC 17025 workflows.
Software & Data Management
Jingfei provides a native Windows-compatible application (Win7–Win11, 64-bit) with real-time spectrum visualization, multi-curve overlay, peak detection, and export to CSV, TXT, or XML. The included SDK offers full low-level register access, asynchronous trigger handling, and memory-mapped data buffers for deterministic timing in automated test systems. Data files embed embedded metadata (wavelength calibration, integration time, temperature, serial number), ensuring FAIR (Findable, Accessible, Interoperable, Reusable) principles. USB hot-plug support enables seamless reconnection without driver reload; firmware updates are performed via signed HEX packages verified by on-chip CRC32 checksums.
Applications
- UV-Vis quantitative analysis of aqueous and organic solutions (e.g., nitrate, COD, chlorophyll-a)
- Time-resolved luminescence spectroscopy in material science (phosphors, quantum dots, OLED emissive layers)
- In-line process monitoring of LED binning, laser diode spectral shift, and plasma emission profiling
- Reflectance-based color measurement and pigment identification in coatings, textiles, and pharmaceutical tablets
- Environmental sensing: solar irradiance mapping, water quality index (WQI) derivation, and dissolved organic carbon (DOC) estimation
- Educational labs requiring rugged, low-cost platforms for teaching spectroscopic fundamentals and chemometrics
FAQ
Is the FLA4000 compatible with third-party software such as OceanView or MATLAB?
Yes—the FLA4000 exposes a documented USB HID protocol and includes a comprehensive SDK with language bindings for Python, C/C++, and LabVIEW. While not natively supported in OceanView, users have successfully implemented drivers using the provided register map and timing specifications.
Can the spectral range be extended beyond 1100 nm?
No—the standard CMOS detector limits operation to ≤1100 nm. For NIR applications up to 2500 nm, Jingfei offers InGaAs-based models (e.g., FLA5000 series) with TE-cooled detectors and custom optical coatings.
What is the thermal stability specification over ambient temperature variation?
The detector exhibits wavelength drift of <0.02 nm/°C and sensitivity drift of 80%.
Does the instrument support synchronized multi-channel acquisition?
Not natively—each FLA4000 operates as an independent node. However, master-slave triggering via shared TTL signals enables sub-millisecond inter-unit synchronization across up to 8 units using external logic controllers.
