Title:
INFRARED LENS, INFRARED OPTICAL SYSTEM, AND INFRARED IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070644
Kind Code:
A1
Abstract:
An infrared lens L transmits infrared rays and is made of a resin. Due to this configuration, material costs can be suppressed, and an aspheric surface can be formed due to good moldability. Moreover, the infrared lens L has an average thickness within the optical effective diameter of 0.5 mm or less. Due to this configuration, good infrared transmittance can be obtained. Consequently, an infrared lens L that is suitable for infrared ray applications can be realized.
