Introduction
Overview
This operating manual introduces the Lighthouse REMOTE 1100,
1104 family of Airborne Particle Counters. Included in this manual are
instructions for inspecting, using and maintaining these instruments.
Description
The R1100 or R1104 instrument has up to four ( R1100 ) or eight
( R1104 ) particle size channels starting at 0.1 microns at a flow of 1.0
CFM.

The instrument uses the Lighthouse Long-Life laser diode light source
and laser beam shaping optics to illuminate a cross section of the air
flow path with a laser beam. As particles move along the flow path,
they cross the laser beam and scatter light. The light scattered is
collected by an imaging optical system onto a photodiode. The
photodiode converts this light into a voltage which is amplified.
The resulting pulse is measured for width and height. The width of the
pulse is proportional to the time it takes the particle to cross the laser
beam and the height (amplitude) of the pulse is equal to the amount of
light scattered by each particle which is proportional to its size.
Additional electronics count the particles and group them based on
