Luminance and Flicker Meter
LF 2.5 mm
High‑speed and precise luminance measurement on small areas
The Prometheus LF 2.5 features a 2.5 mm spot size and a sampling rate of 800k samples/sec, allowing precise luminance, flicker and waveform measurements for display characterization.
- Vastly improved luminosity filter accuracy
- Flicker luminance (Y) function: 800 000 samples/second
- Improved sensitivity for low luminance levels
- Increased large dynamic range
- Highly accurate luminance measurements according to human eye (CIE 1931)
