  1. 90 % uv below 400nm could be shielded by the nano - sio2 sol. the time of the artificial aging of nano - sio2 - modified coatings prepared by the way of in - situ dispersion method was about twice as long as that of the nano - sio2 - modified coatings prepared by dispersing the nano - sio2 powder in the coating directly. on the other hand, the fadeproof time ( reaching the second level of color aberration ) of the nano - sio2 - modified coatings was 1. 83 times as long as that of the national standard for the super coatings

    實驗證明:納米510 :溶膠具有很強的紫外散射屏蔽性能,對400nm以下的紫外光能屏蔽90 %以上;在位分散法納米510 :改性塗料的耐人工老化粉化時間比直接分散法納米510 :改性塗料提高了近1倍,耐變色時間(達到色差2級的時間)是國標優等品要求的1 . 83倍,較相應的未改性塗料提高了約25 % 。
  2. In the retrofocus project, a retrofocus structure with two elements is used in the object lens to enlarge fov and back working distance, in the head of which the negative meniscus have the effect of balancing aberration and deviating rays like a prism. and a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive

    反遠距設計方案中物鏡採用二片式反遠距結構,增大了視場和后工作距離,彎月型負透鏡在前,具有平衡像差和棱鏡的偏向作用;物鏡後放置高折射率標準超半球型浸沒透鏡,滿足小光敏面探測器接收。
