UV power meter

C10427 H10428

Hamamatsu offers a new optical power meter designed to measure absolute power of UV light. This optical power meter has a flat spectral response over a wide UV wavelength range and so can measure the optical power in the spectral response range independent of the spectral emission distribution of light sources.


  • Flat spectral response over a wide UV range
  • Wide light-receiving angle close to cos θ
  • Sensor head even thinner than our current models
  • Calibration certificate attached
  • Ideal for monitoring / controlling light source power for photocatalyst
  • With carrying case


  • Black Light
  • UV LED
  • Ultraviolet Rays (UV-A)
