Diffused Output Reflectors:
Reflectors giving a diffuse output are normally used to reduce the intensity of the reflected IR (heat) impinging on heat sensitive substrates. Most all UV emitting lamp output consists of around 60 percent IR energy. Not only do reflectors focus UV energy but also IR energy. The down side of a diffused reflector array is the reduced curing efficiency in terms of depth of cure and also a reduction of the cure rate which is partially temperature driven.
