Overview
The SPEKTRI 80 Handheld Spectroradiometer is a precision field-deployable instrument engineered for high-fidelity spectral radiometric and photometric characterization of light sources and illuminated environments. Based on a thermally stabilized back-thinned CCD array spectrometer with integrated cosine-corrected input optics, it delivers traceable, high-resolution spectral irradiance measurements across the 380–780 nm visible range (extendable to 350–1050 nm with optional grating configurations). Its optical architecture complies with CIE S 023/E:2013 and DIN 5032-7:2016 Class B requirements for directional response, ensuring accurate angular weighting under real-world illumination geometries. Designed for both outdoor ambient light assessment and controlled laboratory validation, the SPEKTRI 80 supports full-spectrum quantification of photometric, chromatic, and photosynthetic parameters—enabling compliance-driven evaluation in lighting R&D, horticultural lighting design, display calibration, and daylighting analysis.
Key Features
- Thermally stabilized 2048-pixel back-illuminated CCD detector with <0.1 nm pixel resolution (FWHM) and <0.3 nm optical resolution at 550 nm
- Cosine-corrected silicon photodiode input head conforming to DIN 5032-7:2016 Class B angular response specification
- Factory calibration traceable to MIKES (Finnish Metrology Centre), with NIST-traceable reference lamp certificates provided per unit
- Integrated rechargeable Li-ion battery supporting >8 hours continuous operation; battery state-of-charge displayed with ±2% accuracy
- Real-time calculation of 32+ photobiological and photometric metrics including Ev (lx), CCT (K), CIE 1931 (x,y), CIE 1976 (u′,v′), CRI Ra, TM-30 Rf/Rg, PAR (μmol/m²/s), PPFD (400–700 nm), and spectral flicker indices (IEC TR 61547-1 / EN 12464-1)
- Onboard flash memory (16 GB) with timestamped measurement logging and dual-mode connectivity: USB-C host interface + Bluetooth 5.0 for remote control and live data streaming
Sample Compatibility & Compliance
The SPEKTRI 80 is optimized for non-contact measurement of planar and extended light sources—including LED arrays, OLED panels, fluorescent tubes, HID lamps, natural daylight, and architectural lighting installations. It operates within ambient temperature ranges of −10 °C to +45 °C and relative humidity up to 85% non-condensing. All spectral data acquisition protocols adhere to ISO/CIE 19476:2014 (spectral irradiance measurement uncertainty), IEC 62471 (photobiological safety), and EN 12464-1:2021 (lighting of indoor workplaces). The device meets electromagnetic compatibility requirements per EN 61326-1:2013 and carries CE marking under the EU EMC and RoHS directives. Calibration reports include uncertainty budgets compliant with ISO/IEC 17025:2017 for accredited metrology laboratories.
Software & Data Management
The instrument ships with SpectraView Pro v4.x desktop software (Windows/macOS) and a companion mobile application (iOS/Android) for configuration, real-time visualization, and report generation. Raw spectral data are stored in standardized JIS X 0211-compliant .spc binary format and exportable as CSV, XML, or CIE 15:2018-compliant .cie files. Software features include GLP-compliant audit trails, user-defined measurement templates, batch processing of time-series datasets, and automated compliance checking against thresholds defined in IES LM-79, ENERGY STAR Lamps V2.1, and Horticulture Lighting System (HLS) performance guidelines. Data exports support FDA 21 CFR Part 11–compliant electronic signatures when used in regulated GMP environments.
Applications
- LED lighting product development and photometric validation per IES LM-79 and CIE 127
- Horticultural lighting system characterization: PPFD mapping, spectral quantum yield analysis, and phytochrome photostationary state (PSS) modeling
- Architectural daylighting simulation verification and LEED EQ Credit 8.1 documentation
- Display and projector color uniformity testing under variable ambient conditions
- Photobiological safety assessment per IEC 62471 and EN 62471:2008+A1:2013
- Calibration transfer between reference-grade lab instruments and field-deployed units in metrology networks
FAQ
Is the SPEKTRI 80 calibrated to national standards?
Yes—each unit undergoes primary calibration at the manufacturer’s MIKES-accredited facility using NIST-traceable tungsten-halogen and deuterium reference lamps. A full calibration certificate with uncertainty budget is included.
Can it measure pulsed or modulated light sources?
Yes—the instrument supports synchronous integration with external trigger signals (TTL-compatible) and provides flicker metrics including SVM (Stroboscopic Visibility Measure), percent flicker, and frequency-domain spectral ripple analysis per IEEE 1789-2015.
What spectral irradiance units does it support?
Standard output includes W/nm/m², W/nm/cm², mW/cm², and μW/cm²/nm; customizable unit scaling is available via software configuration.
Does it support third-party integration via API?
Yes—SpectraView Pro exposes a documented RESTful API and Python SDK for integration into automated test benches, building management systems (BMS), and LIMS platforms.
How often is recalibration recommended?
Annual recalibration is recommended for ISO/IEC 17025 compliance; however, built-in stability monitoring (via internal reference diode drift tracking) enables condition-based recalibration scheduling.
