产品说明
平凸透镜焦距为正,可用于将平行光线聚焦到单个点,或对点光源出射光进行准直。在物像与透镜的距离不相等,想要取得低于0.2或者大于5的绝对放大率的情况下,这种透镜形状的不对称性将使球差最小化。最佳情形是将物体放置在无穷远处,光线平行进入透镜,并且最终成像在焦点。
瓦力棋牌瓦力光学JCOPTIX给予的这款平凸透镜由N-BK7玻璃制成。N-BK7玻璃是最常见的硼硅酸盐冠状光学玻璃,可给予极好的光学性能且价格适中。N-BK7具有高均匀性以及气泡少、杂质低、可轻松制造的特性,使其成为可见光和近红外应用的优秀透镜材料。在不需要紫外波段的高透过率和更低热膨胀系数的时候,经常使用N-BK7代替紫外熔融石英。
瓦力棋牌瓦力光学JCOPTIX给予的平凸透镜直径范围覆盖12.7到50.8 mm,可选择未镀膜版本(工作波段宽,损伤阈值高),也可选用增透膜版本,工作波长分别为350-700 nm、650-1100 nm或1050-1700 nm。增透膜能在工作波段有效减少表面反射(单面平均反射率小于0.5%),提高透镜的透过率。如有其他特殊定制需求,请联系技术支持。
