Luminance is a photometric measure, reported in cd/m² (or sometimes called nits). For accurate luminance measurements the Prometheus LF is the first
choice, because it makes use of the Admesy custom-coated high-accuracy Y filter.
Both the Asteria and Prometheus LF also offer high-speed sampling to measure flicker. If you have specific needs for your flicker measurements contact Admesy to help you find the best solution for your application.
