I damaged the surface of the AR1 daylight filter (for scanback). It is on the clear part of the two glass filters inside the holder.
I was wondering if anyone could tell me what the use is of this piece off glass. I know most IR block filters are blue (schott) glass, so I guess the blue glass will take off the IR. Does the clear part has a function at all, perhaps it is only to add some thickness to proparly mount the filter?
