These diode blocks can also be found in newer compact laser projectors. You may be lucky and score a broken one at a good deal.
You were able to remove the lens and test the distances?The gang lens on my osram array would not focus cleanly at distance, I bet the N31/34 will be the same, the lenses are not aspheric and the spots will have large wings when you adjust the gang lens distance to try and get a good infinity focus.
Do you use TTL modulation in it or just all time at full power?
When you focus the nubm31t, you would normally get a 2x2mm spot size for this reason.
