Overview
The UPRtek MK350N Premium is a handheld spectrophotometer engineered for high-accuracy spectral radiometric and photometric characterization of light sources in real-world environments. Based on grating-based optical dispersion and CCD linear array detection, it captures full spectral power distribution (SPD) across the visible range (360–780 nm) with 1 nm resolution and calibrated wavelength accuracy ±0.5 nm. Designed specifically for LED lighting development, quality control, and field validation, the instrument delivers traceable measurements compliant with CIE S 025/E:2015 and IES TM-30-15 methodologies. Its compact form factor, battery-powered operation (up to 4.5 hours), and ruggedized industrial enclosure enable reliable use in production floors, outdoor installations, medical facilities, and R&D labs—without dependency on external PCs or darkroom conditions.
Key Features
- Real-time spectral acquisition in ≤3 seconds per measurement, with improved photometric repeatability (±2.5% typical CV under stable ambient conditions)
- Integrated flicker analysis engine sampling at up to 100 kS/s, enabling time-domain waveform reconstruction and calculation of Percent Flicker, Flicker Index, SVM (Stroboscopic Visibility Measure), and temporal frequency spectrum
- Dual-mode spectral evaluation: CRI (Ra, R1–R15) with CRI bar visualization and TM-30-15 metrics (Rf, Rg, color vector graphics, gamut maps)
- 40+ configurable photometric and colorimetric parameters—including CCT, Duv, CIE 1931/1976 chromaticity, luminous flux (via known geometry), PAR (Photosynthetically Active Radiation), and melanopic EDI (Equivalent Daylight Illuminance)
- On-device graphical interface with intuitive icon-driven navigation, live spectral curve overlay, and side-by-side comparison mode for reference vs. test source evaluation
- Self-contained operation: internal rechargeable Li-ion battery, SD card data logging (up to 10,000 spectra), and real-time display of numerical results and spectral plots
Sample Compatibility & Compliance
The MK350N Premium supports direct measurement of all common electrically powered light sources—including discrete LEDs, LED modules, COBs, OLED panels, fluorescent tubes, HID lamps, and smart lighting systems—without requiring integrating spheres or auxiliary optics. For absolute photometric calibration, users may apply optional correction factors based on manufacturer-provided angular response profiles or third-party sphere validation reports. The device conforms to ISO/CIE standards for spectral irradiance and illuminance measurement (CIE 69:2020, CIE 127:2007), and its firmware implements audit-trail-ready data logging aligned with GLP principles. While not FDA 21 CFR Part 11 certified out-of-the-box, raw spectral data export (CSV, XML, SPC) enables integration into validated laboratory information management systems (LIMS) for regulated medical lighting applications.
Software & Data Management
Two dedicated PC applications extend analytical capability: uSpectrum PC provides advanced spectral analysis, batch processing, custom metric scripting, and report generation (PDF/Excel) compliant with ISO/IEC 17025 documentation requirements; uFlicker PC enables deep time-series flicker diagnostics—including FFT-based harmonic decomposition, persistence mapping, and compliance assessment against IEEE 1789-2015 and ENERGY STAR V2.1 thresholds. All software supports multi-language UI (English, Chinese, Japanese, Korean), metadata tagging, and secure export with embedded calibration timestamps and instrument ID. Firmware updates are delivered via signed packages with SHA-256 verification to ensure integrity and traceability.
Applications
- LED manufacturing QA/QC: binning verification, CCT shift monitoring, and TM-30-15 consistency testing across production lots
- Architectural and outdoor lighting design: in-situ illuminance uniformity mapping, glare assessment (UGR estimation), and spectral daylight simulation validation
- Medical and circadian lighting validation: melanopic lux quantification, scotopic-to-photopic ratio (S/P) analysis, and non-visual photobiological safety screening
- Luminaire R&D: comparative SPD modeling, phosphor degradation tracking, and driver-induced flicker signature profiling
- Educational and field service use: portable spectral literacy training, retrofit verification, and energy efficiency audits per EN 13201 and IES RP-8 guidelines
FAQ
Is the MK350N Premium suitable for measuring UV or IR radiation?
No—it is optimized for the visible spectrum (360–780 nm) and does not include UV-enhanced coatings or extended-range detectors.
Can spectral data be exported in standardized formats for third-party analysis?
Yes: CSV (with wavelength-intensity columns), XML (CIE 15:2018-compliant), and industry-standard SPC files are supported.
Does the device require annual recalibration?
UPRtek recommends factory recalibration every 12 months or after 200 hours of cumulative use under high-irradiance conditions; NIST-traceable calibration certificates are available upon request.
What accessories are required for absolute luminous flux measurement?
A calibrated integrating sphere (e.g., UPRtek IS-300 series) is necessary; the MK350N Premium alone measures spectral irradiance/illuminance only.
Is firmware update support provided for the lifetime of the instrument?
Yes—UPRtek maintains backward-compatible firmware releases for all MK350-series devices for a minimum of 7 years from product discontinuation.
