After the BeamWatch is mounted, measure the
distance from any desired reference point on the
laser delivery head to the top face of the camera as
shown right. This value is the
Distance
of the laser
and must be entered into the software during setup
(see section 4.4.2 in the BeamWatch Software User
Guide).
2.1.1 Mounting for Elliptical Beams
There is no automated method for finding the major and minor axes of an
elliptical beam. The BeamWatch unit must be manually rotated to find these
axes. A rotation mount (SP90346) is available as an accessory to assist in this
alignment. After the software is installed and the beam is centered in the
BeamWatch unit, rotate the unit around the beam while viewing the Waist
Width result in the software until max/min values are found. For best
measurements with dual axis BeamWatch units, rotate the BeamWatch until the
major and minor axes of the beam are aligned with the X and Y axes of the
software. It is irrelevant which of the BeamWatch axes views the major or minor
axes of the beam.
2.1.2 Beam Dump
A suitable beam dump is required. An Ophir Power Sensor rated for the power of the laser is recommended. Other options
are acceptable, but must have minimal backscatter, such as a cone type or black absorber power sensor. Contact your
Ophir-Spiricon representative for additional information.
