Nomarski Prism EN
Georges (Jerzy) Nomarski (January 6, 1919 – 1997) was a Polish physicist and optics theoretician. He was the creator of differential interference contrast (DIC) microscopy. The method is widely used to study live biological specimens and unstained tissues and in many languages bears his name. Biography Born in Nowy Targ, Nomarski was educated in Warsaw at the Warsaw University of Technology (known at that time as the ''Warsaw Polytechnic'') and served in the Polish Resistance during World War II. Captured by German forces, he was a prisoner of war until March 1945. After the war when the Soviets supported communists installed their regime over Poland, Nomarski had to escape to Belgium as a political refugee. He studied there briefly before he moved to France for his permanent residence in 1947. He finished his education in France and received his diploma from l'Ecole Supérieure d'Optique Paris (Grande Ecole). In 1950, Nomarski established the ''Laboratoire de Microscopie Optiq ...

Differential Interference Contrast
Differential interference contrast (DIC) microscopy, also known as Nomarski interference contrast (NIC) or Nomarski microscopy, is an optical microscopy technique used to enhance the contrast in unstained, transparent samples. DIC works on the principle of interferometry to gain information about the optical path length of the sample, to see otherwise invisible features. A relatively complex optical system produces an image with the object appearing black to white on a grey background. This image is similar to that obtained by phase contrast microscopy but without the bright diffraction halo. The technique was invented by Francis Hughes Smith. The "Smith DIK" was produced by Ernst Leitz Wetzlar in Germany and was difficult to manufacture. DIC was then developed further by Polish physicist Georges Nomarski in 1952. DIC works by separating a polarized light source into two orthogonally polarized mutually coherent parts which are spatially displaced (sheared) at the sample plane ...

Polish Resistance Movement In World War II
In Poland, the Resistance during World War II, resistance movement during World War II was led by the Home Army. The Polish resistance is notable among others for disrupting German supply lines to the Eastern Front (World War II), Eastern Front (damaging or destroying 1/8 of all rail transports), and providing military intelligence, intelligence reports to the United Kingdom, British British intelligence agencies, intelligence agencies (providing 43% of all reports from German-occupied Europe, occupied Europe). It was a part of the Polish Underground State. Organizations The largest of all Polish resistance organizations was the Armia Krajowa (Home Army, AK), loyal to the Polish government in exile in London. The AK was formed in 1942 from the Union of Armed Struggle (''Związek Walki Zbrojnej'' or ZWZ, itself created in 1939) and would eventually incorporate most other Polish armed resistance groups (except for the communists and some far-right groups).

Soviets
The Soviet people () were the citizens and nationals of the Soviet Union. This demonym was presented in the ideology of the country as the "new historical unity of peoples of different nationalities" (). Nationality policy in the Soviet Union During the history of the Soviet Union, different doctrines and practices on ethnic distinctions within the Soviet population were applied at different times. Minority national cultures were never completely abolished. Instead the Soviet definition of national cultures required them to be "socialist by content and national by form", an approach that was used to promote the official aims and values of the state. The goal was always to cement the nationalities together in a common state structure. In the 1920s and the early 1930s, the policy of national delimitation was used to demarcate separate areas of national culture into territorial-administrative units, and the policy of korenizatsiya (indigenisation) was used to promote involvement ...

Nomarski Prism
A Nomarski prism is a modification of the Wollaston prism that is used in differential interference contrast microscopy. It is named after its inventor, Polish and naturalized-French physicist Georges Nomarski. Like the Wollaston prism, the Nomarski prism consists of two birefringent crystal wedges (e.g. quartz or calcite) cemented together at the hypotenuse (e.g. with Canada balsam). One of the wedges is identical to a conventional Wollaston wedge and has the optical axis oriented parallel to the surface of the prism. The second wedge of the prism is modified by cutting the crystal so that the optical axis is oriented obliquely with respect to the flat surface of the prism. The Nomarski modification causes the light rays to come to a focal point outside the body of the prism, and allows greater flexibility so that when setting up the microscope the prism can be actively focused.
