French student looking for an interferential glass

Aug 12, 2003 2 Replies

Hello,



Is anybody out there who know how I can find an interfetial glass (A.K.A. plan glass). It's a rectangular shape glass which allow you to check the planeity of a surface (all surface). You put the glass on the face, and if the surface is not plan, you see opticals ondulations on the interferential glass.



Pleez help me, I dont know where I can found it. ThanX
