Grimm Laser Aerosol Spectrometerfunctional principle, light source with laser diode
Grimm optical cell like in 180
• Light source by compact laser diode with
multiplex mode, low power consumption
and good temperature stability
• Collimator generates laser curtain
with homogeneous optical field
• Light trap assures low noise due to
very low indirect scattering light

Grimm Laser Aerosol Spectrometerfunctional principle, aerodynamic aerosol focusing
Grimm optical cell like in 180by compact
laser diode with
multiplex mode, low power consumption
and good temperature stability
• Collimator generates laser curtain
optical field
• Light trap assures low noise due to
very low indirect scattering light
• Inlet focus particles aerodynamically
into optical field, no border zone error
• Rinsing air circuit and outlet nozzle
design assure straight pass through
the laser, no vagabonding particles

Grimm Laser Aerosol Spectrometerfunctional principle, PIN diode and wide field reflector
Grimm optical cell like in 180
• Light source by compact laser diode with
multiplex mode, low power consumption
and good temperature stability
• Collimator generates laser curtain
with homogeneous optical field
• Light trap assures low noise due to
very low indirect scattering light
• Inlet focus particles aerodynamically
into optical field, no border zone error
• Rinsing air circuit and outlet nozzle
design assure straight pass through
the laser, no vagabonding particles
• Fast and robust photo diode detector for
90° scattering light detection
• Special wide field reflector improves
detection limit for small particles and
reduces sizing effects by refractive index
