[Calculator for micrometric analysis of histological structures from negatives, photographic plates and photographs]

The description of a counting device for morphometric analysis of histological structures from negatives, photographic plates and photographs, assembled on the basis of the colony counter and a binocular attachment to MBC-1 microscope, is presented. The counting of dots or histological structures on a definite area is performed using an electrical pen. The results are recorded by the counter. The proposed device allows a morphometric analysis in various types of morphological investigations to be carried out rapidly and with a sufficient precision.
