QE - series
The QE series are modular low-profile heads, designed for ease of installation in tight optical
setups.
These detectors have square apertures, providing better compatibility with rectangular beam
profiles, such as pulsed gas lasers.
A corner mounting thread permits diagonal mounting of the heads to accommodate longer
rectangular beams.
These heads can be used with an optional finned heatsink to extend the power range.
The QE Series can also be used with QED optional attenuator / diffuser

for improved
compatibility with high-energy lasers.
QE -QED series
The QE-QED series are calibrated with QED installed, they can be used from 0.3 to 2.1µm, but
cannot be used without attenuator.

The DB-
15 male “Smart Interface” connector contains an EEPROM (Erasable Electrical Programmable
Read-Only Memory) programmed with the calibration sensitivity and other data relating to the specific
QE
joulemeter in use. Faster set-ups are obtained because the monitor automatically adjust to the
characteristics of the joulemeter, when the “Smart Interface” is connected to the monitor. The cable length
is 3 feet.
The DB-
15 “Smart Interface” connector pin-out is (see Fig. 1-1):
