QE Series Joulemeter Instruction Manual Version 3.0 April 2014

4 OPTIONAL ACCESSORIES

4.1 QED ATTENUATOR / DIFFUSER

The QED attenuators increase the energy, energy density, average power and average power

density capabilities of the QE Series.

They are engineered to typically transmit 30-50% of the incident radiation to the detector in a near

Lambertian pattern (very wide diffusion pattern).

They feature ease of installation and removal.

The QED attenuators can be optionally calibrated @1.064µm when purchased at the same time as

a corresponding QE joulemeter.
