Why do you need to use IR Cut Filter? Different effect with IR pass filter and IR cut filter.
How to distinguish a coating side?  
IR-cut filter(ICF) is a short pass (or called a lowpass filter) filter that blocks infrared light and transmits the visible range light(400~700nm).
Infrared (IR) cut-off filters are used with color CCD or CMOS imagers to produce true color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible. This can be done with two optical techniques: absorption or reflection. Absorptive filters are made with special optical glass that absorbs near infrared radiation.If you need this absorptive IR blocking filter,please choose our blue glass filter. Reflection type filters are essentially short-pass interference filters that reflect infrared light with high efficiency.Our IBG series IR blocking filters are you best choice with low cost and fast delivery.
If you're after IR cut filter made by quartz crystal,pls check our OLPF filter.
