Abstract: An optical filter is configured to have a regular transmittance of 60% of higher for light having a wavelength of 950 nm. The optical filter is also configured such that in a state in which a light resistance test of irradiating the optical filter for 300 hours with light from a xenon arc lamp having a wavelength not shorter than 300 nm and not longer than 400 nm and a wattage of 120 W/m2 is performed, the optical filter exhibits a change in C* having an absolute value of 6 or smaller between before and after the light resistance test, the C* being measured by the SCE method by use of a spectrophotometer.

Abstract: The present invention strengthens the security level of an infrared security system. The infrared security system for managing unlocking of a lock includes: at least one detection unit that includes an optical laminate and an infrared detection device which is disposed so as to receive infrared light via the optical laminate; and a security system that operates on the basis of output from the infrared detection device. The security system is configured to generate time-series data that indicates motion of a subject on the basis of a subject signal generated when the infrared detection device receives, via the optical laminate, infrared light which has been emitted from a light-emitting device toward the subject and which has been reflected by the subject, and to unlock the lock on the basis of the time-series data.

Abstract: An optical multilayer body (100) according to the present invention has a first main surface and a second main surface that is on the reverse side of the first main surface. This optical multilayer body (100) comprises: an optical filter layer (110) which transmits infrared light, while diffusely reflecting visible light; and a recording medium layer (120) which is arranged on the second main surface side of the optical filter layer, while having a pattern that can be read with infrared light through the optical filter layer. This optical multilayer body is configured such that the pattern is not visible through the optical filter layer.
