Compact, fast industrial light meter
High-speed robust Luminance, Illuminance & Flicker meter
Admesy’s Asteria is a high-speed measurement device suited for
luminance, illuminance and flicker measurements. Based on the popular Admesy
platform the Asteria is designed for in-line use with integrated calculating
power for easy implementation and high speed measurement results in production
settings. The Asteria is available in multiple configurations: the lens
based system is capable of measuring luminance [cd/m²] and flicker, its cosine
corrector configuration allows illuminance [lux], luminous intensity [cd] and
flicker measurements. Fibre versions are also available to connect to remote
cosine correctors, lens systems or connect to integrating spheres.
Absolute luminance or illuminance & luminous
intensity measurement according to the human eye: CIE1931 luminosity
All flicker measurement standards supported for
display: Contrast, JEITA, VESA
Lighting flicker methods: flicker percentage,
index and IEEE 1789 recommendation
Measure high and low frequencies at the same time
through a high sample rate [186.567 samples/second] and large memory size
RS-232, Ethernet connections and trigger in & out for ideal system and
Windows, Linux, OSX and embedded systems compatible
SCPI command interface for easy integration in other applications
Supported in all major programming languages Labview /
Labwindows / Visual Studio [C++, C#, VB]/ etc.
- USBTMC standard compliant
- Integrating- and sampling mode available
- 3 gain stages for every mode
- Auto-range function
User calibration function and pre-programmed
Flicker measurements at the US Department of Energy
Department of Energy (DOE) is responsible for advancing energy security and
economics. As a consequence the Department of Energy is also very active in
research for lighting applications -- especially Solid-State-Lighting (SSL).
In 2016 the
Department of Energy compared several
purchasable flicker measurement solutions to their laboratory test solution.
The Admesy Asteria was positively evaluated and is since then used in a
permanent installation at the PNNL’s Lighting Metrology Laboratory as the
reference device for flicker measurements for the Department of Energy.
2018 the US Department of Energy published a new report on Characterizing
Photometric Flicker with Handheld meters, where the Asteria was used as a
reference for the handheld meters under comparison.
article from 2016 and 2018 are certainly
worth reading for those interested in light measurements and flicker
characterization. The articles are freely available:

At DOE the
Asteria is used in a permanent setup, but the Asteria is very small and compact
and can also easily serve for “on the go” handheld measurements… all you need
is a laptop or tablet.
