透镜,滤光片研发生产.jpg



首先今天给大家先介绍几个我们生活中普遍存在的光学滤光片,例如矫正视力的近视镜上有减反射滤光片,汽车反光镜上有高反射滤光片,商务办公中广泛使用的投影机核心部件更是集合了多种滤光片,去医院检查身体使用的生化检测仪核心部件之一的单色器很多都是采用窄带滤光片,数码相机中使用了长波通滤光片短波通滤光片盛天集团,各种光学仪器,液晶显示器以及防伪技术,光通讯,激光技术等等都与滤光片技术的发展密不可分。可以说没有滤光片技术的发展作为基础,很多近现代新兴技术都难以取得目前的成就,因此谁又能说光学滤光片不重要呢?没有和我们的生活融为一体呢?

 一般透过的波长较长,多用做红外滤光片盛天集团。后者是在一定片基上,用真空镀膜法交替形成具有一定厚度的高折射率或低折射率的金属-介质-金属膜,或全介质膜,构成一种低级次的、多级串联实心干涉仪。膜层的材料、厚度和串联方式的选择,由所需要的中心波长和透射带宽λ确定。
