Disclosed is a hybrid Infrared Ray (IR) cut-off filter for a digital camera, which includes an absorption filter plate for absorbing infrared rays, a reflection coating layer formed on a top or bottom side of the absorption filter plate so as to reflect infrared rays, and an anti-reflection...
It also depends on the CMOS camera. Most, I think, do need some external filtering for IR (and UV?), but not all. I just picked up the ASI2600MC-P, and according to ASI, an IR cut filter is built in. They don't talk about UV. I am looking at the ASI294MC. It would be ...

The IR filter that is provided with the camera should work fine. To get the best performance from the DSI (which I presume would be similar to the DSI II) I take two sets of images; one using the color sharp model the other using color soft. Color sharp gives the sharpest image, but...

由于camera sensor不同于人眼,除了可以感受可见光,还可以感受近红外光(Near IR),这样就会造成sensor对红光感受过强,形成色偏。 所以在目前的相机里都会在sensor前安装IR cut filter, 也有的叫NIR cut filter。 加了IR filter的影响有三: 把近红外的射线去除掉。

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: ...
