Energy Detectors

Our pyroelectric energy meters cover a very wide range, going from nanojoules to several tens of joules per pulse. They also come in various sizes, from 8 mm to 95 mm in diameter and most of them are available with an optional attenuator.

QED ATTENUATOR

DESCRIPTION


The QED attenuators increase the energy, energy density, average power and average power density capabilities of the QE Series detectors. They are engineered to typically transmit 30-50% (@1.064 µm) of the incident radiation to the detector in a near Lambertian pattern (very wide diffusion pattern). Their slide-in casing make them easy to install and remove and they are held securely in place with the use of simple set screws. Since they become part of the detector, it is important to understand how they will affect the calibration.

 

CALIBRATION OPTIONS


When buying a QE detector with a QED attenuator, 4 calibration options are available:

 

STANDARD CALIBRATION

   

QE Detector Alone:

Fully calibrated, from 248 - 2500 nm

With QED Attenuator:

Not calibrated (Calibrated by the user)

EXTRA QED CALIBRATION
QED-CAL-1

   

QE Detector Alone:

Fully calibrated, from 248 - 2500 nm

With QED Attenuator:

Calibrated at one wavelength (532 nm or 1064 nm)

CALIBRATED AS A PAIR (-QED)
QED-CAL-2

   

QE Detector Alone:

Not calibrated

With QED Attenuator:

Fully calibrated, from 308 - 2100 nm

FULL CALIBRATION
QED-CAL-3

   

QE Detector Alone:

Fully calibrated, from 248 - 2500 nm

With QED Attenuator:

Fully calibrated, from 308 - 2100 nm
(This configuration comes with a DB-15
adaptor for the QED calibration)
