The drawer is withdrawn towards the front and above the platform. In the bottom (10a) of the drawer are other housings (10d) for interchangeable objectives in the form of cells. Other housings can be formed as holes to suspend the objective mountings. These mountings can be grips or staples fixed in the drawer bottom.
