The Waechter Model V monocular microscope dimensions are: height 25 cm and diameter of the optical tube 2.9 cm. The objective is made up of three series of lenses. The one with the lowest magnification is 9mm in diameter; This is followed by a set of three 10mm diameter lenses and finally a set of four 13mm lenses. in diameter, which are superimposed by thread.

Its focus system is the same as the previous model. The iron foot, blued in black, is in the shape of a horseshoe. It has dimensions of 8 x 6.5 x 1.30 cm. This microscope was very deteriorated and its layer of varnish blackened; We have eliminated it by electrolysis, the apparatus having recovered its original shine.

In this collection we have models No. IV and V. Both are the same in dimensions and focus mechanism, they only differ in optics, which is more complex in model V.
