چکیده
Macro vivo fluorescence imaging is becoming more and important in the medical field. It also necessary to design optical system for visible light of NIR-II detector. This paper discusses method wide spectrum achromatic from NIR-II. Based on ZEMAX, a zoom designed freely observe experimental targets fields view 3.1–18.6°. The four components layout was adopted by system, which suitable 8.2 mm (1/2 inch) CCD, with an f-number 5.0~6.0, range 25 mm~150 mm, working spectral band 400 nm~1700 nm, full field MTF ≥ 0.3 at spatial frequency 100 lp/mm, maximum distortion ≤±3%. All elements adopt standard spherical, can correct all kinds aberrations well meet each part’s basic processing requirements.
