Overview
The Jingfei FLA6300 Fiber Optic Spectrometer is a compact, thermoelectrically cooled, back-illuminated CCD-based spectrometer engineered for high-sensitivity spectral acquisition in demanding low-light applications. Operating across an extended UV-VIS-NIR range (200–1100 nm), it leverages a high-quantum-efficiency linear CCD array to deliver robust photon detection performance—particularly critical for weak-emission spectroscopy modalities including fluorescence, Raman scattering, and time-resolved luminescence. Its thermoelectric cooler (TEC) actively stabilizes the detector at up to 20 °C below ambient temperature, significantly suppressing dark current generation and enabling sustained integration times without thermal noise saturation. This architecture ensures consistent spectral fidelity under variable laboratory conditions and supports quantitative intensity calibration traceable to NIST-traceable standards.
Key Features
- Back-illuminated 2048-pixel CCD detector with peak quantum efficiency >90% in the 300–800 nm range
- Thermoelectric cooling system maintaining detector stability at ΔT = –20 °C relative to ambient
- Optical resolution down to ≤0.1 nm FWHM (dependent on grating groove density and entrance slit width)
- Low stray light design (<0.1%) achieved via optimized optical path geometry and internal baffling
- High linearity (>99.8%) across 90% of full-scale response, validated per ISO 14785:2016 spectral linearity test protocols
- Rugged aluminum alloy chassis (182 × 110 × 50 mm, 1.6 kg) with EMI-shielded enclosure compliant with IEC 61326-1 for laboratory electromagnetic compatibility
- USB 2.0 interface supporting isochronous data transfer at up to 480 Mbps; compatible with Windows, Linux, and macOS via vendor-provided SDK
Sample Compatibility & Compliance
The FLA6300 interfaces seamlessly with standard SMA905 fiber-optic probes (e.g., 200 µm or 400 µm core diameter), integrating into modular optical setups for liquid cuvette measurements, solid-sample reflectance, gas-phase absorption, or micro-volume fluorescence assays. Its broad spectral coverage accommodates excitation sources from deuterium lamps (UV) to tungsten-halogen (VIS-NIR) and laser diodes (e.g., 532 nm, 785 nm for Raman). The instrument complies with key regulatory frameworks applicable to analytical instrumentation: CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); RoHS 2011/65/EU material restrictions; and mechanical safety per EN 61010-1:2010. While not certified as a medical device, its performance characteristics align with ASTM E275–22 (UV-VIS-NIR spectrophotometer verification) and ISO/IEC 17025:2017 requirements for measurement uncertainty estimation in accredited testing laboratories.
Software & Data Management
Bundled with Jingfei SpectraView™ v3.x software, the FLA6300 supports real-time spectrum acquisition, multi-curve overlay, peak identification, baseline correction, and export in CSV, TXT, and JCAMP-DX formats. The SDK provides C/C++, Python (PySpectra), and LabVIEW drivers enabling full control over integration time (1 ms–65 s), gain settings, and TEC setpoint. Audit-trail functionality logs all parameter changes and acquisition timestamps—supporting GLP-compliant workflows where required. Data integrity is reinforced through checksum-verified firmware updates and optional hardware-level write protection for calibration coefficients stored in non-volatile memory.
Applications
- Fluorescence lifetime and quantum yield measurements in organic dyes, quantum dots, and biological fluorophores
- Stimulated Raman scattering (SRS) and spontaneous Raman spectroscopy using 785 nm or 532 nm excitation
- UV-Vis absorption kinetics for reaction monitoring in chemical synthesis and catalysis research
- LED and OLED spectral power distribution (SPD) characterization per CIE S 025/E:2015
- Plasma emission analysis in semiconductor process chambers
- Environmental water quality assessment via absorbance-based nitrate/nitrite quantification (EPA Method 353.2)
FAQ
Is the FLA6300 suitable for integration into OEM analytical instruments?
Yes. Its compact form factor, USB 2.0 interface, deterministic timing, and comprehensive SDK make it widely adopted as an embedded spectrometer in OEM platforms—including portable Raman analyzers, benchtop fluorimeters, and inline process monitors.
Does the spectrometer support external triggering?
Yes. TTL-compatible trigger input (rising-edge active) enables synchronization with pulsed lasers, shutter controllers, or motion stages—critical for time-gated fluorescence or pump-probe experiments.
What calibration options are available?
Factory-calibrated wavelength (Hg/Ar lamp lines) and radiometric (NIST-traceable tungsten halogen source) calibrations are included. Optional recalibration services are offered annually with certificate of conformance.
Can the 70 µm slit be replaced in the field?
No. Slit replacement requires optical realignment and factory recalibration. Custom slits (e.g., 25 µm, 100 µm) must be ordered pre-installed at time of purchase.
Is the USB interface compatible with industrial PC environments?
Yes. The device uses a standard USB CDC ACM class driver; no proprietary kernel modules are required. It operates reliably in long-duration acquisitions under Windows IoT Enterprise and Linux RT kernels when configured with appropriate USB power management policies.
