Qty. 3  Rod Optical Glass Needle - Laser Optics - R&D

Approx 30mm in length 

Please examine all the pics on this lab.

I obtained these optical Glass units from an R&D lab that did laser optics experiments.

These Glass optical rods have a round diameter that thin down to a round point.

I really don't know too much about these little optical units.  Examine the pics.

Thanks for having a look.
