Published on 19 July 2018, Author: Andreas Gross

Nominated for the Innovation Award Bavaria 2018: Spectroradiometer BTS2048-UV-S with BiTec sensor for fast, high-quality UV measurements

Many applications in the UV range could until now only be realised with slow, complex, expensive, and above all large double monochromators. The systems required complex installation and logistics. Much more compact and stable structures can be realised with array spectroradiometers. Until now, the limiting factor has always been inadequate scattered light suppression in the UV range.

With the innovative BTS2048-UV-S device series from Gigahertz-Optik GmbH, a production-ready technology has been developed to overcome this limitation. Thanks to its innovative filter-based scattered light suppression and its DAkkS-traceable calibration (DIN EN ISO/IEC 17025), the BTS2048-UV-S showed very good absolute conformity over several orders of magnitude compared with an internationally accepted reference instrument (double monochromator) in an intercomparison.

The considerably shorter measurement time (a few seconds compared to many minutes) and the small size (reduction in volume by 98 %) open up new areas of application and investigation.
In addition, the new technology can be used anywhere, operating in a compact, weatherproof box with low energy consumption, meaning that the system allows for much easier solar UV and ozone measurement without major infrastructure and logistical requirements, even in exposed locations such as the alpine area (mount Zugspitze).

Other applications include radiation risk assessment in occupational safety and the measurement of UV LEDs, to name but a few.

The lighting industry requires high accuracy spectral light meters that can handle complex measurements. These include measurement of pulse width modulated light sources and the ability to measure both indoors and outdoors lighting, determination of thermal transient behavior of lamps, their flicker properties and so on. The primary criterion that such meters must always meet is the quality of their photometric features. 

With the BTS256-EF, Gigahertz-Optik GmbH, a renowned measuring device manufacturer, offers a universal measuring device for the determination of all relevant light parameters in general lighting. The new device has been updated which includes a redesign of some of its features. Changes include the enhancement of the wavelength range from 360 nm to 830 nm and the implementation of all functions of the BTS256-E, BTS256-EF and BTS256-PAR meter. 

Due to its redesign, the BTS256-EF is able to fulfill an even broader range of requirements. Its measurement features include photometric and colorimetric parameters, Photosynthetically Active Radiation (PAR) of plant grow lights, Human Centric Lighting (1), Stroboscopic Visibility Measure SVM (2), Short-Term Flicker Pst (2), and ASSIST Flicker Perception Metric Mp

The BTS256-EF is also available with an optional Wi-Fi function.

The CSS-45 detector incorporates a powerful microprocessor which performs not only data acquisition but also all necessary lighting calculations. Both USB 2.0 and RS 485 interfaces are standard enabling the flexible configuration of single and multi-detector based systems. An optional software development kit supports integration into third party application software. 

With its wide spectral range from 360 nm to 830 nm the CSS-45 is ideal, for example, as a high accuracy photometric and colorimetric detector (according to CIE S023). The precision diffuser provides excellent cosine correction (f2 ≤ 1.5 %). The optical bandwidth correction feature (CIE 214) further improves the quality of the spectral measurement data. Manual and auto gain settings enable a wide measurement from 1 lx to 350,000 lx for illuminance and color measurements. 

The robust housing and its connectors are splash proof, and therefore suitable for use in industrial applications. A variant with protective glass dome in front of the diffuser is available. A special feature of the detector is its remote-controlled shutter, which allows a dark level measurement to be made at any time.

Manufacturers of lamps and luminaires for general lighting purposes must consider light flicker when qualifying EMC immunity requirements. In addition to the influence of mains voltage fluctuations, flicker effects caused by the lamp and the luminaire itself must be taken into account. 

With the BTS256-EF, Gigahertz-Optik GmbH, a renowned measuring device manufacturer, offers a universal measuring device for the determination of all relevant light parameters in general lighting. Combined with a LPS-CH-500 programmable AC source, the BTS256-EF becomes a comprehensive flicker test system for lamps and luminaires including voltage fluctuation immunity tests in accordance with IEC TR 61547-1:2017. 

The BTS256-EF supports all current flicker measurements: Percent Flicker, Flicker Index and FFT Frequency analysis, Short term flicker severity, Pst (*), Stroboscopic Visibility Measure, SVM (*), and ASSIST Flicker perception metric, Mp.

The MSC15 spectral light meter now includes display modes for the accurate measurement of neonatal phototherapy lamps in accordance with the latest standards and guidance, irrespective of the lamp type or manufacturer. It directly displays total irradiance for bilirubin, Ebi (mW/cm2) in accordance with IEC 60601-2-50:2009+A1:2016 as well as average spectral irradiance (µW/cm2/nm) in accordance with the latest American Academy of Pediatrics recommendations.

Neonatal phototherapy is widely used for the treatment for neonatal hyperbilirubinaemia, a condition in which there is too much bilirubin in the blood. This causes a yellowing of the infant’s skin, known as jaundice. Effective phototherapy requires sufficiently high irradiance with appropriate wavelengths, generally accepted as ‘blue light’.

Optimising treatment dosimetry, agreement on best practises and comparing research have all been hindered by the large variability of measurement data produced by the many proprietary broadband radiometers employed, each with its specific spectral response and typically tailored to specific lamp or LED types. The MSC15 spectral light meter conveniently and effectively eliminates these issues.

Additionally, the MSC15 can be used to measure any light source, displaying spectral irradiance from 360-830nm as well as photometric and colorimetric data including photopic, scotopic and melanopic illuminance, color rendering indices, color temperature and CIE chromaticity.

After eighteen years in the works CIE Technical Committee TC 2-47 has completed and published CIE 220:2016. [1] This technical report describes quality indices for UV radiometers, which enable manufacturers and users to characterize instruments on a common basis. To harmonize CIE documents, the quality indices described in this document relate to the quality indices described in Joint ISO/CIE International Standard ISO/CIE 19476:2014(E) (formerly CIE S 023/E:2013).

The work began in the First Workshop of the "Thematic Network for Ultraviolet Measurements" in Espoo, March 2 and 3, 1998. The Network was funded by the Standards, Measurements and Testing programme of the Commission of the European Communities, as project number SMT4-PL96-9329.    

Within the Working Group 1 "Guidance for UV power meter classification for particular applications" with chair Anton Gugg-Helminger the document "Characterizing the Performance of Integral Measuring UV-Meters" was prepared. It is published in the UV news Issue 6/November2000. [2]

This publication was then adopted by CIE technical committee TC2-47 finishing the report in 2016.

Since UV filter radiometers very often measure light sources which are spectrally different than the light sources with which they were calibrated. As a result an uncertainty occurs called spectral mismatch error, defined as the ratio of the effective responsivity of the radiometer with respect to the radiant quantity of the test source to the effective responsivity with respect to the reference source.

UV radiometers in general are designed for various actinic spectra and different spectral ranges. So instead of only one defined reference light source spectra, CIE Illuminant A, used in photometry, three reference light source spectra are proposed in CIE 220 to support the generic spectral characterization of UV radiometers for various applications. For situations where three spectra are not sufficient for evaluating the spectral mismatch ten other light source spectra are provided in the UV News Issue 6/November2000 [2].

The report includes an explanation and methods for evaluating and correcting for spectral mismatch error assuming specific spectral responses are known. When detailed technical specifications are provided by the UV filter radiometer manufacturer, CIE 220:2016 information and methods can be employed to compare different meters.

Also included in the report:

  • Example evaluation of a UV-A radiometer designed for UV hazard assessment per ICNIRP/ACGIH guidelines
  • Short and long wavelength range response characteristics of UV radiometers and the impact on measurement results are explained
  • Recommendations for UV radiometer data sheet content and specifications
  • Uncertainty evaluation discussion including a list of major sources of uncertainty for UV radiometer calibration
