Short Wave Infrared Camera Optical System for The Long Range Image Monitoring

摘要

The present invention relates to a short wave infrared camera optical system for monitoring a long range, which includes a plurality of lenses (L1 to L7) disposed along an optical axis, wherein the lenses (L1 to L7) receive a wavelength band of 0.9 to 1.7 μm. The lens (L7) adjacent to a detector (D) moves along the optical axis to correct the defocus occurring when the object changes the distance and changes the temperature.
