A lens spanner wrench:
Spanner Wrench(1/32") Great Tool for Lens - eBay (item 160410529135 end time Apr-03-10 23:07:17 PDT)
This is for removing lenses and optics mounting rings that have two small holes on either side of the optic:
They are commonly found in high-end portable lasers and lab-style lasers. This tool is indispensable for anyone interested in repairing DPSS lasers.
I have one of these spanner wrenches. They are absolutely the BEST possible answer for removing lenses that have the holes in the mounting ring or for a locking ring with the holes in it, to lock the lens down into position. No more fumbling around with two small screwdrivers or other pointed objects, trying to get them both to sit in the holes at the same time, & then to try to apply torque to them to get a stubborn ring loose. Also, no more scratched lenses, when one or both of your pointed objects slips out of its hole, & scrapes across the lens surface. GREAT TOOL & well worth the expense.
