INFRARED TRANSMISSION MEMBER, INFRARED CAMERA USING THE SAME AND METHOD FOR PRODUCING INFRARED TRANSMISSION MEMBER

摘要

PPROBLEM TO BE SOLVED: To provide an infrared transmission member provided with an inexpensive protective film having satisfactory infrared transmissivity, and also having excellent properties such as low water absorptivity and a low ratio of a dimensional change, to provide an infrared camera using the same, and to provide a method for producing an infrared transmission member. PSOLUTION: The infrared transmission member is provided with an infrared transmission substrate 11 having a first main face 15F on which infrared rays are made incident and a second main face 15B provided so as to be confronted with the first main face 15F, and from which the incident infrared rays emit; antireflection films 12 respectively covering the first main face 15F and the second main face 15B in the infrared ray transmission substrate 11; and a protective film 13 covering the antireflection film 12 in the first main face 15F, and the protective film 13 covering the antireflection film 12 in the first main face 15F is composed of a thermoplastic liquid crystal polymer.
