ACCU-CAL™ 50V Visible Radiometer

for use with Visible Light Curing Systems  CE Marked - Available Globally


Consistent curing requires periodic monitoring of visible energy intensity or dose. The ACCU-CAL™ 50V radiometer is simple to operate and offers repeatable measurement of visible light. The ACCU-CAL 50V can measure visible light energy emitted from lightguides (3 mm, 5 mm, and 8 mm), flood systems, and conveyors.

With a spectral sensitivity from 400 to 470 nm (blue portion of the visible spectrum), the ACCU-CAL 50V measures intensities from 1 mW/cm2 to 40 W/cm2. A specially designed photo sensor assembly protects the photo sensor from the high temperatures sometimes associated with today’s high-intensity spot lamps.

  • Measures range up to 40 W/cm2
  • Sensitive at measuring stray or reflected visible light (as little as 1 mW/cm2)
  • Only one calibration per year
  • Set screw locks lightguide in place
  • PTB and NIST traceable
