against material and /or workmanship defects when used under normal operating conditions. The
warranty does not cover recalibration or damages related to misuse.

Gentec-EO will repair or replace at its option any wattmeter or joulemeter which proves to be defective
during the warranty period, except in the case of product misuse.

Any unauthorized alteration or repair of the product is also not covered by the warranty.
The manufacturer is not liable for consequential damages of any kind.
In the case of a malfunction, contact the local Gentec-EO distributor or nearest Gentec-EO office to

obtain a return authorization number. Return the material to the address below.

Lifetime Warranty

Gentec-EO will warranty any thermal power and energy detector head for its lifetime as long as it has
been returned for recalibration annually from the date of shipment. This warranty includes parts and labor
for all routine repairs including normal wear under normal operating conditions.

Gentec-EO will inspect and repair the detector during the annual recalibration. Exceptions to repair at
other times will be at Gentec-EO’s option.

Not included is the cost of annual recalibration or consequential damages from using the detector.
The only condition is that the detector head must not have been subject to unauthorized service or

damaged by misuse. Misuse would include, but is not limited to; laser exposure outside Gentec-EO’s
published specifications, physical damage due to improper handling, and exposure to hostile
environments. Hostile environments would include, but are not limited to excessive temperature,
vibration, humidity (>80%), or surface contaminants; exposure to flame, solvents or water; and connection
to improper electrical voltage.

1.1 INTRODUCTION

The Gentec-EO QE Series is a robust line of high performance and high accuracy pyroelectric

joulemeters. Each modular unit is built for durability, compactness and ease of operation.
The QE optical absorber exhibits high damage thresholds and can operate at high rep-rates. The

QE series can be used to even higher energy levels with QED attenuator / diffuser.
The QE Series benefits from the use of a DB-15 male, “Smart Interface” connector, containing an

EEPROM (Erasable Electrical Programmable Read-Only Memory) programmed with the
calibration sensitivity, the spectral correction factors at different wavelengths and other data
relating to the specific QE Series joulemeter head. This connector permits the monitor to
automatically adjust to the characteristics of the joulemeter being connected.

The C0 version of the QE series (with BNC connector) does not have the “Smart Interface”

function. These joulemeters cannot be used with monitor. They must be used with an
oscilloscope or an OEM acquisition system.

All QE Serie are also available with the the INTEGRA USB Connector. This option only needs a
Computer or tablet PC using the PC-GENTEC-EO. It also a Smart Interface programmed with
the calibration sensitivity, the spectral correction factors at different wavelengths and other data
relating to the specific QE Series joulemeter head.

Every QE Series joulemeter features high intrinsic responsivity and high insensitivity to
electromagnetic interference.

The QE Series also offers an exceptionally wide dynamic range and permits energy
measurement from UV to far IR.

QE Series joulemeters are designed for user-friendly energy measurement of pulsed lasers with
monitor.

QE Series joulemeters require no power source. They can also be used with 1 M1 input
impedance oscilloscopes2 (or fast chart recorders). The calibrated V/J sensitivity is documented

in the calibration certificate of each unit. The spectral correction of this sensitivity is also
documented in the “Personal wavelength correction” certificate.

Each probe3 also includes a standard optical stand and post. An appropriate damage test target
is provided, as a safety precaution, for all QE models.

The capacitance of the cable linking the joulemeter to the electronic readout and the readout input

impedance (capacitance and resistance) constitute the total impedance load seen by the detector. The

total load capacitance, excluding the integral cable should be  30 pfd.
A DB-15 to BNC adaptor is required.
For the CO version, the post and stand are optional.

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 / diffuser4 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.

1.2 QE SERIES “SMART INTERFACE” CONNECTOR 5

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):

NOTE : Consult Gentec-EO for supply voltage requirements.

1.2.2 Integra USB connector

The Integra USB Connector is an integrated monitor that allows to plug the head directly into a
computer. It has the same serial commands as the MAESTRO and a few extra one’s (see the PC­Gentec-EO Manual) and uses the same PC-Gentec-EO software. All specifications are the same.
The cable length is 6 feet.
