Patent ID: 8280238

Claim:
An adapter system comprising: a first adapter configured to couple a first image modifying device to a second image modifying device, a proximal portion of the first adapter configured to be connected to the first image modifying device, a distal portion of the first adapter configured to be connected to the second image modifying device, wherein the distal portion is configured to mate with the second image modifying device via a coupling, the distal portion including a locking mechanism selectively engageable to releasably secure the coupling; a second adapter releasably connectable to the first adapter, the second adapter being configured to couple the second image modifying device to a third image modifying device, a distal portion of the second adapter being configured to be connected to the third image modifying device, a proximal portion of the second adapter being configured to be connected to the second image modifying device; and an infrared light source configured to generate a beam of infrared light along an axis of the infrared light source, the infrared light source attached to one of the first and second adapters at a pivot joint and rotatable about the pivot joint between multiple positions, the axis of the infrared light source being parallel in each of the multiple positions with respect to the axis of the infrared light source in each of the other multiple positions.
