Title:
赤外線センサ用集光装置とその製造方法
Document Type and Number:
Japanese Patent JP6868439
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light condensing device which can efficiently guide infrared rays emitted from a measuring object to an infrared sensor 3, and can quickly eliminate dew formation when dew is formed due to a change in humidity environment around the device.SOLUTION: A first synthetic resin 5 having high compatibility with plating is formed inside, a second synthetic resin 6 having lower compatibility with the plating compared to the first synthetic resin 5 is formed outside, and the synthetic resins are molded by two-color molding. An inner peripheral surface 14 of the first synthetic resin 5 is mirror-finished by plating treatment. On the other hand, an outer peripheral surface 15 of the second synthetic resin 6 is not mirror-finished, and a texture of the synthetic resin is rough-finished to enhance heat absorption property and heat dissipation property.SELECTED DRAWING: Figure 1
