ANALYSIS, TEST AND MEASUREMENT Centauri portable energy meter BTS256-EF flicker test system


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, a 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: per cent flicker; flicker index and FFT frequency analysis; short-term flicker severity; Pst (CIE TN-006); stroboscopic visibility measure; SVM (CIE TN-006); assist flicker perception metric; and Mp. www.gigahertz-optik.de


MKS Instruments announced the Ophir Centauri at Photonics West, a compact, portable laser power/energy meter for measurement of laser performance over time. Functions include density, scale factor and normalise against baseline. Available in single and dual-channel versions, the Centauri is compatible with all standard Ophir thermal, photodiode and pyroelectric sensors, including BeamTrack power/position/size sensors. The Centauri’s graphical functions include digital with bargraph, analogue needle, line plot, pulse chart, pass/fail, position, stability and real-time statistics displays. The dual channel option supports split and merged graphical displays. Sophisticated power and energy logging allows logging of every point at up to 10kHz. The Centauri’s maths functions


WaveGo pocket-sized light measurement system


The WaveGo, from Wave Illumination, offers simple, yet accurate, measurement for characterisation of light sources. Paired with a smartphone app, the handheld device measures absolute irradiance, lux, colour temperature, colour rendering, TM30, Melanopic lux and PAR. WaveGo’s compact size and


connected data management make it an ideal solution for lighting manufacturers to test and prove quality in the plant and on field sales calls. The device uses a


miniature spectrometer with 3nm optical resolution to

integration into larger systems and USB flash drive output. A TTL output can be used in conjunction with pass/fail limits. www.mksinst.com


deliver highly accurate light measurement over the 350- 800nm wavelength range, from 1 to 1,000,000 lux. The smartphone app captures single and continuous measurements with one touch. Users can select any combination of absolute irradiance spectrum, lux, CIE 1931 colour, CRI (Ra, R1-15), TM30 (Rf and Rg), and PAR for each measurement taken. With virtually no learning


curve, plant engineers can verify quality throughout the manufacturing process, and sales staff can demonstrate conformance to specifications in the field. Results include a GPS location tag to easily track multiple measurement


sites. Data can be saved locally, viewed and exported via email right on the phone. The WaveGo is due for release in mid-2018. www.waveillumination.com

Diafilm ETC700 CVD diamond heat spreader


At Photonics West, Element Six launched its Diafilm ETC700 CVD diamond heat spreader, which has excellent heat dissipation and is, for the first time, electrically conductive. Diafilm is a proven thermal management

material ideal for high-power RF, optoeletronics and high-voltage power semiconductor devices. It reduces thermal gradients near a device, making heat sinks more efficient and allows higher power devices to be used without increasing the system size or reducing the


operating ambient temperature. Diafilm singulated heat spreaders can lower device temperatures, improve reliability and expand performance capability. The material outperforms copper, silicon carbide and aluminium by factors of 3 to 10. www.e6.com
