Abstract
A counting device including a wall that delimits an internal space; an object counter that is positioned in the internal space and includes a measuring lens, which optically delimits a detection zone outside the counting device. The wall of the counting device includes an aperture positioned in front of, preferably centered relative to, the measuring lens, the measuring lens and the aperture being arranged to transmit to the counter a flux emitted by the objects present in the detection zone.
Claims15
A counting device comprising:
- a wall delimiting an internal volume,
- an object counter positioned in said internal volume, said counter comprising:
- a measurement element arranged to record and/or detect a flux at least one wavelength between 5 and 12 micrometers emitted towards said counter by objects present in a detection zone, and
- a measurement lens optically delimiting the detection zone outside said counter, the lens being assembled to the rest of the counter through a tight junction protecting the measurement element from dust and/or moisture coming from outside the counter,
- wherein the wall of the counting device comprises a window:
- comprising germanium, preferably being entirely comprised of germanium, and
- positioned in front of, preferably centred on, the measurement lens, so as to form a housing between the lens and the window
- assembled to the rest of the wall through a tight junction protecting the counter from dust and/or moisture coming from outside the wall,
- said measurement lens and said window being arranged to transmit the flux emitted by objects present in said detection zone to said counter.
