Italian term
lente a ventaglio
Italian to English

Engineering (general)
Encountered in a list of products for domotics systems: "Rilevatore di infrarossi con fotocamera - lente a ventaglio." It is just a list, so no other context I'm afraid. Any ideas for that "lente a ventaglio"? The literal "fan lens" gets quite a few finds in Google, but almost always together with "ventilation" which doesn't seem to fit here. Thanks in advance.

This is not much more than a guess. However, see this site and similar sites on surveillance cameras: https://addison-electronique.com/lentille-pour-camera-1-3-cs...

The sensor’s lens views its coverage area as a series of ***fan-shaped coverage zones***, with small gaps in between, and is most sensitive to motion that occurs between each zone (lateral to the sensor).
