Laser Beam Profile
The invisible measurement laser beam emitted from AR3000 sensor has a rectangular profile that
expands (diverges) as its distance from the sensor increases. This table indicates the approximate
beam dimensions at different distances from the sensor.

509x10000[20x390]
Note that the specified divergence (2 mrad or 10 mrad) is for the faster expanding laser axis and
that the height expands faster on the 2 mrad model while the width expands faster on the 10 mrad
model.

Sensor Maintenance
The AR3000 sensor requires little maintenance from the user. The sensor lenses should be kept
clean of dust buildup as a part of regular preventative maintenance. Use compressed air to blow
dirt off the window or use delicate tissue wipes. Do not use any organic cleaning solvents on the
sensor. If a sensor does not function according to specifications, contact Schmitt Industries, Inc.
Do not attempt to loosen any screws or open the sensor housing.
2.8.
Sensor Service
The AR3000 sensor has no user-serviceable parts. Refer all service questions to Schmitt
Industries, Inc. Do not attempt to loosen any screws or open the sensor housing.
