Laser diodes with a wavelength between 635 nm and 780 nm can be used for fine particle detection. A robot vacuum cleaner, for example, can use these types of laser diodes to discriminate different dust sizes in order to characterize and database the dust and waste that is being sucked and collected. Other common uses can be found in air purifiers and air conditioners.
