產品說明
平凸透鏡焦距為正,可用于將平行光線聚焦到單個點,或對點光源出射光進行準直。在物像與透鏡的距離不相等,想要獲得低于0.2或者大于5的絕對放大率的情況下,這種透鏡形狀的不對稱性將使球差最小化。最佳情形是將物體放置在無窮遠處,光線平行進入透鏡,并且最終成像在焦點。
晶萃光學JCOPTIX提供的這款平凸透鏡由N-BK7玻璃制成。N-BK7玻璃是最常見的硼硅酸鹽冠狀光學玻璃,可提供極好的光學性能且價格適中。N-BK7具有高均勻性以及氣泡少、雜質低、可輕松制造的特性,使其成為可見光和近紅外應用的優(yōu)秀透鏡材料。在不需要紫外波段的高透過率和更低熱膨脹系數(shù)的時候,經(jīng)常使用N-BK7代替紫外熔融石英。
晶萃光學JCOPTIX提供的平凸透鏡直徑范圍覆蓋12.7到50.8 mm,可選擇未鍍膜版本(工作波段寬,損傷閾值高),也可選用增透膜版本,工作波長分別為350-700 nm、650-1100 nm、1050-1700 nm、400-1100 nm。增透膜能在工作波段有效減少表面反射(單面平均反射率小于0.5%),提高透鏡的透過率。如有其他特殊定制需求,請聯(lián)系技術支持。
