1 - GENERAL
Laser Point’s OEM Detector Heads of AH Series are power and energy measurement devices
designed for their integration in laser sources or laser machines for direct monitoring. They can be
applied to all kind of laser sources and machines to allow OEMs with diagnostic tools that coupled
with leaky mirrors or splitters can continuously monitor laser sources and laser systems.
Laser Point’s AH Detector Heads are thermopile detector units based on a sensor integrated with
an amplifying/accelerating electronics and hosted in a suitable mechanical housing, that according
to the power sustainable by the sensor are either convection air cooled (AHA) or water cooled
(AHW).
Unpacking and inspection
Each OEM Detector Head has been carefully inspected and tested prior to shipment. Unpack and
assure that no damage occurred during transport and handling. Any damage must be immediately
reported to Laser Point and to the Carrier.
Do not use any device if it looks damaged, or if you suspect that it does not operate properly.
Operating environment
Allow at least 5 minutes of warm up time after the turn-on to achieve maximum stability of the
electronics. Refer to the specs attached to this manual for environmental and operating conditions.
2 - INSTALLING THE AH OEM SENSOR HEAD SERIES
Installation must be performed by an operator qualified to
the use of electrically operated devices. LaserPoint is in
no way liable for any damage resulting from misuse, or
use above rated limits of the instrument.
2.1 - GENERAL
This series includes compact, conduction or water cooled
heads: the setup is made by a sensor disk, a housing, and
an electronic board providing amplification and acceleration
of natural response times of sensors and a connecting device.
Typical response times for AH series amplified
heads is approx 0.8 sec., depending on sensor
type. The maximum applicable power depends on cooling;
in any case do not exceed 1.5 times the rated maximum
power for short term operation (2 min max), for a properly
cooled sensor.
To avoid the sensor damage, be sure the laser
beam power/energy density does not exceed the
maximum rated power/energy density to prevent
the absorber coating damage.
Coating damage appears as discoloration or in worse cases, by the emerging of the sensor disk
metal. The coating damage can affect also significantly the measurement sensitivity, so for a safe
use refer to the attached specs.
