If you are still looking for the lens, I'd suggest either the Nikkor 105 micro, or the Nikkor 200 micro. As Carla said, you need to base the lens choice on the camera to subject distance, and fingerprints are generally no longer than an inch square. A 60 or 70mm lens is going to place the camera too close to take advantage of all the lights from your dome; or it will cause you to place your camera farther away and you will not fill the frame with the print.
I am curious to know more about your set-up and what you are photographing. I am a forensic photographer, and those in my field use RTI for fingerprint imaging (as well as footwear, tire impression, tool marks, etc.).
