ABSTRACT:
A drawing attachment having a focusing system, a power changer system and a telescope, when used in conjunction with an infinity-corrected microscope, permits superimposition of the object viewed through the microscope and a drawing surface for making a drawing of the object being observed. The size of the board is varied by the power changer to permit adjustment of the relative size of the object to the board. The device is designed to be used with an infinity-corrected microscope and is attached to the microscope in the parallel-light zone between the objective and the telescope lens of the microscope.
