采用氩离子束刻蚀制作与一种128×128元PtSiIRCCD摄像芯片匹配的单片硅折射微透镜阵列.所制成的微小光学阵列元件的填充系数高于95%,每单元硅折射微透镜为矩底拱面形,其近轴光(3~5μm光谱波段)的焦距约为80μm,给出了硅折射微透镜阵列的表面探针和扫描电子显微镜测试结果
The Silicon refractive microlens arrays coupled with a large area PtSi IRCCD of 128×128 is fabricated by photolithographys and Ar ion beam etching.The filling factor of the micro optics components fabricated is more than 95%.The focal length of the rectangular arch microlens is about 80μm.The microstructure of the Si microlens arrays is analyzed by the scanning electron microscope and the surface style measurement.
