2.2 Quick power and energy measurement procedure
This section applies to all MAESTRO versions. It will show you the fastest way of making a laser power
and energy measurement with the MAESTRO and a Gentec-EO power or energy detector.
The monitor automatically recognizes all the Gentec-EO power heads and energy heads of version 4 or
higher. All customized technical data required for optimum operation of the detector will be automatically
downloaded from the EEPROM in the DB-15 connector. These data include all the necessary head
parameters such as sensitivity, model, serial number, version, wavelength correction factors, time
response and others. The MAESTRO doesn’t support energy detectors before version 4.
Quick power and energy measurement procedure:
1- Install the power or energy detector head on its optical stand.
2- First, slide the connector latch to the right to unlock the connector.
3- Turn the MAESTRO off and connect a compatible power or energy detector head to the
MAESTRO using the PROBE INPUT JACK (see Fig. 1-2). The Maestro allows hot-swapping
between heads.
4- Slide the latch to the left to lock the connector into place.
5- Switch the MAESTRO ON using the I/O key.
6- Power heads will default the MAESTRO to power measurement; energy heads will default the
MAESTRO to energy measurement. The display will default to a dual display in real time and
scope (Fig 2-1) in auto range mode.
7- Remove the head’s protective cover and start the laser.
Put the detector head into the laser beam path. Leave it there for a few minutes, until the
detector has reached an equilibrium temperature. The entire laser beam must be within the
sensor aperture. Do not exceed maximum specified densities, energies or powers. For the
most accurate measurement, spread the beam across 60% to 80% of the sensor area.
Attention: Power heads can be used with both CW and pulsed lasers.
- Energy heads can only be used with pulsed lasers.
