Photopic Luminance Meter

Hagner ERP-105 + Hagner Detector SD-27

This device measures the absolute photopic light intensity, i.e. photopic luminance. Can be used to measure e.g. the intensity of lights, glow-in-the-dark materials, and the fading of persistent luminescence.


  • Detectable range: 0.01–20,000 mcd/m²
  • Same spectral response as human eye in well-lit conditions, i.e. photopic response
