Overview
The UpTek MF250N Handheld Flicker and Spectral Analyzer is an integrated optical measurement instrument engineered for field-deployable, real-time assessment of temporal light modulation (TLM) and spectral photometric characteristics. Based on high-speed CMOS sensor acquisition synchronized with embedded spectral calibration algorithms, the MF250N applies the IEC TR 61547-1:2019 and IEEE 1789-2015 methodologies to quantify flicker metrics—including Flicker Index and Flicker Percentage—while simultaneously capturing full visible-range spectral power distribution (SPD) from 380 nm to 780 nm. Designed for lighting engineers, quality assurance personnel, and third-party testing labs, the device delivers traceable, repeatable measurements without requiring external PCs or darkroom setups. Its compact form factor (185 × 75 × 42 mm), integrated rechargeable Li-ion battery (≥8 hrs continuous operation), and intuitive OLED interface enable rapid in-situ verification during product handover, factory audits, or on-site lighting commissioning.
Key Features
- Real-time dual-mode acquisition: Simultaneous flicker waveform capture and spectral analysis at up to 10 kHz sampling rate
- Five operational modes: Basic (CCT, CRI Ra/R9, Illuminance, λP, Integration Time), Spectral (SPD, chromaticity coordinates x,y/u’,v’), Flicker (Flicker Index, Flicker %, VESA FMA, FFT Frequency, FFT Magnitude), Frequency (dominant modulation frequency detection), and Amplitude (time-resolved relative intensity vs. frequency)
- Optical system calibrated per CIE 1931 2° standard observer; spectral resolution ≤ 5 nm FWHM
- Auto-dark calibration routine initiated at power-on—required before each measurement session to null thermal drift and sensor offset
- IP52-rated enclosure with anti-reflective, scratch-resistant sapphire lens window
- On-device data logging (up to 10,000 records) with timestamp, GPS metadata (optional), and export via USB-C or Bluetooth 5.0 to UpTek’s compliant software suite
Sample Compatibility & Compliance
The MF250N supports direct measurement of all common light sources including LED modules, OLED panels, fluorescent tubes, HID lamps, and automotive headlamps—regardless of beam angle, dimming protocol (PWM, CCR, analog), or driver topology. It complies with photobiological safety requirements per IEC 62471 and is validated against reference-grade laboratory spectroradiometers per NIST-traceable protocols. For regulated environments, the instrument supports audit-ready data export with embedded measurement uncertainty values and conforms to GLP documentation standards. While not FDA 21 CFR Part 11–certified out-of-the-box, its firmware architecture enables secure user authentication, electronic signature logging, and immutable record generation when deployed with UpTek’s enterprise software license.
Software & Data Management
Measurements are managed via UpTek SpectraLink v4.x desktop application (Windows/macOS) and mobile companion app (iOS/Android). The software provides FFT-based flicker spectrum visualization, comparative overlay of multiple SPDs, automated pass/fail reporting against customizable thresholds (e.g., IEEE 1789 “low-risk” limits), and batch export to CSV, XML, or PDF formats suitable for ISO/IEC 17025-accredited lab reports. Raw spectral and time-series datasets retain full 16-bit depth and include metadata headers specifying calibration date, sensor temperature, integration time, and firmware revision—ensuring full metrological traceability.
Applications
- Lighting OEMs performing pre-shipment flicker validation per ENERGY STAR Lamps V2.1 and DesignLights Consortium (DLC) Premium requirements
- Contractors verifying flicker compliance during commercial LED retrofit projects under ASHRAE 90.1–2022 Annex G
- Display manufacturers assessing backlight modulation artifacts in LCD and microLED video walls
- Automotive Tier-1 suppliers validating interior ambient lighting per UNECE R128 and SAE J1383
- Academic researchers studying circadian rhythm impacts of temporal light modulation in human-centric lighting studies
FAQ
Is the MF250N suitable for measuring high-frequency flicker (>3 kHz)?
Yes—the instrument samples at 10 kHz with anti-aliasing filtering, enabling accurate characterization of modulation frequencies up to 4.5 kHz.
Does it require annual recalibration? What is the recommended calibration interval?
UpTek recommends annual recalibration against NIST-traceable standards to maintain measurement uncertainty within ±0.5% for illuminance and ±150 K for CCT. Calibration certificates include measurement uncertainty budgets per ISO/IEC 17025.
Can the device measure pulsed or strobed light sources?
Yes—its adaptive trigger logic synchronizes acquisition to transient events, supporting single-pulse, burst-mode, and irregularly modulated waveforms.
Is dark calibration mandatory before every use?
Yes—dark calibration compensates for thermal noise drift and ensures baseline stability. The device enforces this step upon startup and will not proceed to measurement until completed.
What spectral irradiance units does it report?
The MF250N outputs spectral irradiance in µW/cm²/nm and photometric units (lux, cd/m²) derived via CIE 1931 V(λ) weighting; all values are corrected for cosine response error per CIE 127:2007.
