Abstract:
Disclosed is an optical member in the form of a film or a thin plate. The optical member contains near infrared absorbing particles comprising crystallites of an oxide containing at least Cu and P and having a number average aggregated particle size of at least 20 nm and at most 200 nm. Further, a near infrared cut filter, a solid-state imaging element, a lens for an imaging device and an imaging/display device are disclosed. They comprise a near infrared absorbing layer containing near infrared absorbing particles comprising crystallites of an oxide containing at least Cu and P and having a number average aggregated particle size of at least 20 nm and at most 200 nm.
