POPS (Portable Optical Particle Counter)

POPS (Portable Optical Particle Counter)

The Portable Optical Particle Counter (POPS) is a light-weight particle counter designed for aerosol particle size distribution measurements from unmanned aerial platforms, indoor environments, ground-based sensor networks and clean room monitoring. The POPS accurately measures particle diameters between approximately 0.15 to 3.0 um using single-particle light scattering with a power consumption of ~ 5 W.

The POPS can be supplied with a variety of enclosure types depending on the desired application or sold without an enclosure for users desiring maximum configurability.

Schematic of POPS optical cavity, showing 405 nm laser diode and beam dump. Sample particles enter cavity through inlet novel and transit the laser beam, scattering light that is collected by a spherical mirror on the bottom of the cavity. Light is focused onto the detection region of a photomultiplier tube and scaled to particle diameter using a theory-based calibration response function.
