MIRROR FOR CAMERA SYSTEM AND CAMERA SYSTEM

A mirror for camera system includes a substrate, a mirror layer, a fluorescent layer and an excitation window layer. The substrate is provided at a position opposed to an objective lens of an infrared camera, and transmits visible light and infrared light. The mirror layer is provided on a main surface of the substrate, which is the side opposed to the infrared camera, and reflects visible light and transmits infrared light. The fluorescent layer is provided in at least a part of the surface of the mirror layer, and emits at least infrared light as a result of receiving predetermined excitation light. The excitation window layer is provided so as to cover the fluorescent layer, and transmits the excitation light and reflects, at least, the infrared light.
