Lifetime Warranty
Gentec-EO will guarantee any thermal power and energy detector head for its lifetime, as long as it has
been returned for recalibration annually, from the shipment date. 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. Repairs at other times will
be at Gentec-EO’s option.
The cost of annual recalibration, or consequential damages from using the detector is not included.
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, or surface contaminants; exposure to flame, solvents or water; and connection to
improper electrical voltage.

1. HP SERIES POWER DETECTORS
1.1. INTRODUCTION
The Gentec-EO HP Series power detector family includes HP100A-3KW-HE, HP100A-4KW-HE,
HP60A-10KW-GD and HP100A-12KW-HD.
- The HP100A-3KW-HE detector has dimensions of 127 mm x 127 mm and an aperture
of 100 mm.
- The HP100A-4KW-HE detector has dimensions of 127 mm x 127 mm and an aperture
of 100 mm.
- The HP60A-10kW-GD detector has dimensions of 127 mm x 127 mm and an aperture
of 60 mm.
- The HP100A-12KW-HD detector has dimensions of 127 mm x 127 mm and an
aperture of 100 mm.
- The high power surface absorber sensors are designed for use at high average power
densities.
The HP detectors can measure between
- 100 W and 3 KW of average power for HP100A-3KW-HE,
- 100 W and 4 KW of average power for HP100A-4KW-HE,
- 300 W and 10 KW of average power for HP60A-10KW-GD.
- 300 Wand 12 KW of average power for HP100A-12KW-HD.
*For lower power, consult Gentec-eo
The HP-D0 detectors are supplied with a 180 cm length flexible cable with output connection options
of a DB-15 "intelligent" male connector.
NOTE: To eliminate possible damage, do not carry the detector using the connector cable.
Some HP detectors are supplied with a stand (optional).
For cases where Gentec-EO’s monitors don’t automatically read the wavelength correction factor,
you can use your detector’s “Personal wavelength correctionTM Certificate” to adjust the power you
read to a power corrected for a particular wavelength.
Call your nearest Gentec-EO distributor to replace the sensor disk and/or to recalibrate the head.
For Gentec-EO’s nearest office contact information, see p. ii, Contacting Gentec Electro-Optics Inc.

1.2. POWER DETECTOR CONNECTORS
1.2.1. DB-15 “intelligent” connector
The DB-15 male "intelligent" connector contains an EEPROM (Electrically Erasable Programmable
Read-Only Memory) with different information related to the HP Series detector head in use: detector
model, calibration sensitivity, applicable scales and wavelength correction factor for up to 20
wavelengths.
This connector, available in the HP, allows the P-LINK, S-Link, SOLO 2, UNO, TUNER, MAESTRO
(detector model, calibration sensitivity, scale and wavelength correction factor) monitors to adjust
their characteristics automatically to the power sensor being connected. No calibration procedure is
required when installing the power heads, allowing for faster set-up.
The DB-15 connector pin-out is composed of (see Fig. 1-1):

1.2.2. USB connector
The USB connector allows using the HP on a PC. The PC interface, PC-HP, features statistical
calculation, graphics displays and data logging options. It also gives real time measurement of
the cooling flow rate and temperature.
A standard USB cable of 5 meters is supplied with the HP. If a longer cable is required, please
contact Gentec-EO for more information.
A USB power adapter (201221) can be ordered with the required AC plug ; USA (201222), UK
(201223), European (201224) and Australian (201225).
1.2.3. Cooling water
The fluid used to cool the HP must be clean water.
Water Fittings and tubing :
- The HP is equipped with 3/8’’ (OD) tube push to connect fittings.
- It must be used with plastic pressure tube systems (like PE tubes).
The fittings is not compatible with copper or stainless steel tubes.
- The metric version of the HP is supplied with an adapter kit (201993) for 10 mm tube (OD).
The kit contains two push to connect 3/8’’ to 10 mm tube adapters and two 3/8’’
coupling tube stems.
The coupling stem is inserted between the HP and the adapter.
Please note that the tube size is written on the adapter output (10 or 3/8).
Water Quality:
- The HP series cooling fluid must be water, do not use glycol or other additive that changes
the coolant’s heat capacity.
- Use filtered (< 10µm) water to avoid any residue.
Gentec-eo can provide an external water filter (202149) if water quality is an issue.
- Distilled water can be used, but it is not recommended to use highly deionized ultra-pure
water because the water cavity is not completely inert.
- If an algaecide must be used in the chiller, we recommended Optishield Plus or equivalent.
- If chloride is present in the system, the concentration should not exceed 25 PPM and the PH
maintained at 7.0.
Water temperature:
- The cooling water can be between 15 and 25°C but must always remains above the dew
point.
- The ideal set point is 20.0°C, where the HP is calibrated.
- Water temperature stability is very important since variations (1 to 60 seconds) in the
temperature can be interpreted as laser power fluctuation.
- Regulate the temperature with a chiller or a re-circulator.
- The water temperature can be monitored with the PC interface PC-HP.
Water Flow rate:
- Flow rate stability is very important since the measured power is directly proportional to the
flow. Variation (1 to 60 seconds) in the flow rate can be interpreted as laser power
fluctuation.
- The flow rate must be adjusted with a valve. A lower flow rate causes a slower response
while increasing the signal to noise ratio. A higher flow rate causes a faster response,
reducing signal to noise ratio.
- The water flow rate can be monitored with the PC interface PC-HP.
Note: All these parameters should remain in the range stated in the specifications.
