IR cut filter的两种类型: 吸收式。 反射式。 吸收式的ir filter是用某种特别镀膜的光学玻璃,可以吸收某个波段的光。 反射式的ir filter是利用short pass 干涉滤波器,把NIR波段的光反射出去。 下图就是两种类型IR filter的透射率曲线。 红蓝色曲线是 吸收式, 绿色是反射式。 两种类型的优缺点: 反射式的优点: ...
现在有的厂家在在吸收式IR filter里引入了干涉滤波器,可以更好的改善截止特性。把NIR波段透射率做的更低同时可以滤除UV波段。 如果你的手机相机模组是超薄的设计,就可以考虑用这种IR filter,可以有效减小Chomatic Abberance。
