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

• 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
