Document Type and Number:
Japanese Patent JP2004085378
Kind Code:
A
Abstract:
To provide a particle visualizing device usable without enclosing a surrounding environment in a dark room, having a simple structure, and composable at low cost.
This particle visualizing device for visualizing particles in the air is equipped with a light source device 3 for irradiating light into the air, and a dark part constitution part 7 for constituting a dark part on the background side of irradiation light irradiated from the light source device 3. The particles are visualized by contrast between scattered light of the particles by the irradiation light from the light source device 3 and the dark part constitution part 7.
