    The new model Protami

Hensoldt Wetzlar #13270, Protami Field or Travelling Microscope. Marking on the top of the outer case.

The Hensoldt Protami was first introduced in 1925. Before 1935, an improved model, the one shown here, was introduced. This example is of pre-WWII vintage. The outer case and the microscope are constructed of metal and brass with painted and chrome surface finishes. The cased microscope measures 7 inches tall, while the microscope is 10 inches tall with both drawtubes fully extended as shown in the photos. The microscope is focused by means the knurled collar located midway on the body of the microscope. The triple turret objective holder is equipped with objectives marked T, M, and P (n.a 1.30, 1/12). The latter is an oil immersion objective while the T objective is divisible for obtaining the lowest power settings. These objectives, along with various setting of the drawtubes, are designed to provide magnifications in the range 40-1200. The two drawtubes each have three calibrations for use with each objective. Additionally, the microscope is equipped with an Abbe condenser with iris diaphragm, removable stage clip, flat and concave mirrors on an adjustable arm, and under the stage, a removable storage container for immersion oil. The stage can be flipped out of the optical path for easier access.
