Chapter 2 Hardware Configuration
This chapter walks through how to setup and start using your BeamWatch.
2.1 BeamWatch Standard Mounting
The BeamWatch unit must be mounted to a stable surface where
the laser can pass through the entrance and exit apertures
unobstructed.
The center of the entrance aperture is located 50mm from the
crosshair marked on the top of the camera (see image right).
Position the BeamWatch unit at the nominal focus position along
the laser axis, and make sure the beam waist is as close to the
camera axis as possible.
There is a scribe mark on the side of the camera that references
this position. The calibrated distance from the top of the
BeamWatch to the center of the detector array can be found on
the calibration sticker.
To obtain results within
±
5% accuracy, the camera must be
aligned perpendicular to the beam with minimal tilt (<5°) in all
directions and the beam must lie in the plane of the camera focus. Use
either a translation stage or the laser robotics to facilitate the
positioning of the beam in the camera focus plane.
Once in the desired location, secure the unit with four ¼-20 or M6
screws in the slots, two on each side. If not mounted in a fixed position,
measurement error and/or damage to the unit may occur.
