Ge schlieren video projector lens & machined alum mount
WE HAVE SOME LENSES FROM GE VIDEO Schlieren PROJECTION EQUIPMENT. THERE ARE THREE DIFFERENT TYPE HERE AND I WANT TO LIST THEM INDIVIDUALLY. ALL ARE MARKED GENERAL ELECTRIC AND MADE IN JAPAN. SOME HAD LABELS THAT SAID NIKON. ALL ARE MACHINED FROM ALUMINUM AND BLACK ANODIZED. THIS ONE HAS A 1 3/4" LENS AT ONE END, AND A DOUBLE 2" LENS AT THE OTHER WITH ADJUSTABLE FOCUS. THERE IS ALSO AN ADJUSTABLE CROSSHAIR WITH KNURLED THUMB SCREWS AND A REAL NICE THREADED 3.5" ALUMINUM CAP.shelf C4
