A polarization microscope with laser illumination system has an advantage over a lamp-lit system (the efficiency of a laser lighting unit with a total power of 20 mW is equivalent to a lamp system with a power of > 100 W).

The directions of scientific research and development of the B.I.Stepanov Institute of Physics are currently:
* Laser physics, development and creation of laser systems and technologies for medicine, ecology, industry, metrology and information protection;
* Physical and nonlinear optics, the disclosure and use of the patterns of propagation of high-power laser radiation in various media;
* Optical spectroscopy, development and application of methods and instruments for studying the properties and structure of various materials, including biotissues;
* Nanooptics and Nanomaterials;
* Quantum optics, investigation of quantum properties of electromagnetic radiation in computer science and cryptography;
* Investigation of the structure and properties of atomic-molecular structures and the creation of new optical materials, systems, instruments and technologies on this base;
* Plasma physics and plasma technologies: investigation of the plasma interaction with fields and matter; development and application of methods for plasma diagnostics, development of technological applications of gas-discharge and laser plasma
* Micro- and optoelectronics: LED technology, solar cells, microwave technology, microelectromechanical and sensor systems and devices;
* Physics of Fundamental Interactions and Nuclear Reactions - Investigating the Structure of the Microcosm and the Universe.
