Nothing special. Piece of metal. I just use leftover m42 tubes for that purpose.

Not exactly. It's used on inverted microscope and placed between condenser and subject (assumed petri dish). It's just plain sheet of black material obscuring condenser lens.

This however is often not possible in multi-user labspaces. The CKX is often located in normal cell culture labs for quick inspection of cultures and not in dedicated microscope rooms for measurement which are usually dark.
