Optical Technology

Giving you multiple PM values

Simultaneously


Principle of

Operation


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




optical field



• 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














• 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


Grimm Laser Aerosol Spectrometerfunctional principle, output data and gravimetric filter


•t source by compact laser diode with














• Special wide field reflector improves

detection limit for small particles and

reduces sizing effects by refractive index

• 31 size channels, 6 sec. time resolution,

PM10, 2.5,1 or TSP or PMc

• Built in 47mm PTFE filter for gravimetric

mass validation
