Abstract

Dual-band common aperture camera can take into account advantages of both near infrared and visible light. It not only ensures rich color information access, but also can take full advantage of better through fog and high sensitivity low light detection capability of near infrared detection. Dual-band common aperture camera with working band of 450 nm ~ 650 nm and 750 nm ~ 900 nm is designed, with field angle of 35°× 20°, F number 1.5, and globally complex double-Gaussian structure used. Results show that MTF is more than> 0.4 at 50 lp/mm, system diffuse spot is less than 10 μm, and distortion is less than 3%.
- optical design,
- dual-band common aperture camera,
- dual Gauss structure,
- large relative aperture,
- medium field of view
