The SLM 250 incorporates an embedded infrared laser module, a motor to spin the laser, encoders
to measure the rotation angle, the connector to provide power and data communications with the
unit, and the electronic circuitry that allows measurements to be taken at ranges up to 250 metres
from the instrument.
The two windows on the laser module protect the transmitting and receiving optics. It is through
these windows that the infrared measuring laser is fired and then received back into the instrument.
It can fire at up to 36,000 times per second.
The laser can range up to 250 metres. The actual range in any given project will depend on a
number of factors, such as atmospheric and environmental conditions, and the reflectivity of the
surface being targeted.
The laser is housed in an aluminium casing. This ensures that the SLM 250 is highly ruggedised
and may be used in demanding environments.
The flange at the bottom of the SLM 250 allows it to be mounted onto a stable surface (see section
15, “Appendix A – Mechanical drawings”). Its construction means it can be mounted vertically or
horizontally, with no loss of performance.
