Abstract:
A structure includes: a near infrared transmitting filter that shields light in a visible range and allows transmission of at least a part of light in a near infrared range; and a member that is provided on an optical path of the near infrared transmitting filter on at least one of an incidence side into the near infrared transmitting filter or an emission side from the near infrared transmitting filter, allows transmission of light in a near infrared range, and has a refractive index of 1.7 or higher for the light in the near infrared range.
