Hi all --
Has anyone encountered this lens diameter before? I extracted it from a Blue Ray module, it's supposed to be a 405nm aplanatic asphere (according to patents). The diameter appears to be about 3.7 mm (that was the ID of the plastic tube that held it, measured with calipers). I now need to mount it. Are there standard lens mounts for this lens diamenter? M9x0.5 is usually for ~6.5 mm lenses. Thorlabs does not seem to have a standard adapter for 3.7-8 mm diam. I've got M3x12 mm penny washers which I could put into an SM05 tube, but i was wondering if there was a better way.
