This Trackspot part is called...??

I want to order two items and am not sure of their correct names.

The first one is a thick lens that is attached to a L-shaped piece of aluminum and is located right after the lamp assembly. Can someone confirm that this is called a "Hot Mirror"? Also, mine has cracked glass - can the whole assembly be replaced instead of dealing with RTV to attach it to the existing L-bracket?

The second part is a sort of "hub" that you attach to the motor shaft and holds either the color wheel or gobo wheel.

Any assistance, as always, is appreciated.
