Dental Curing Light Straight Guide, Light Pipe

Description

Nearly new, straight light guide with excellent optics.  The OD of the barrel (where it goes into the light) is 11.6mm and the light face (exit pupil) is about 13mm.
I don't remember which light this is from, but it is smaller than my Optilux 500 requires.  So double check the measurements.
These sell for hundreds of dollars new and this one is nearly so.  A great value if this is the size and style you need.
