COMPOSITION, INFRARED PASS FILTER AND METHOD FOR FABRICATING SAME, AND INFRARED SENSOR

摘要

Provided is a composition whereby it is possible to form an infrared pass filter which even when extremely thin (for example, a thickness of 1µm) is able to pass infrared beams (particularly near-infrared beams) therethrough with little noise originating from visible light components. The composition is configured such that when a film with a thickness of 1µm is formed, the maximum value of light transmissibility in the thickness direction of the film is in a range of wavelengths of 400-750nm is 20% or less and the minimum value of light transmissibility in the thickness direction of the film in a range of wavelengths of 900-1300nm is 90% or more. Also provided are an infrared pass filter, a method for manufacturing said infrared pass filter, and an infrared sensor, which employ said composition.
