I recently got a Chromega E Dichroic II enlarger by way of an ugly Ebay transaction. The enlarger arrived with a smashed infra-red filter on the diffuser box, which I have temporarily replaced with plain glass. Is the Ifra-red filtering really necessary for the proper functioning of the Dichro head? I haven't had any experience with one before and haven't a clue. Initially, I plan only to enlarge B&W, but may give color a shot some day.

Any input appreciated...
