Abstract
A wide range of optical instruments based on laser radiation sources are available on the market. Many of them utilize optical systems to focus the radiation on an object. In this case, a beam of a specific wavelength is emitted by a laser and formed in the rear focal plane of the optical system—a specialized objective lens. This paper examines the design of high-aperture monochromatic optical systems for focusing laser radiation at fixed wavelengths characteristic of the most widely used modern laser sources. Optical calculations for specific lens objectives are presented, and the possibility of standardizing their individual design parameters is demonstrated.

Labor-Microscopes (Russian Federation)
Dmitry N. Frolov was born (1961) in St. Petersburg, Russia, where he was educated at the Institute of Precision Mechanics and Optics (today the University of Information Technology). He also graduated from the graduate school and received the title of candidate of technical sciences (PhD). His specialty is the design of optical systems, associated with the design of opto-mechanical and optoelectronic devices. For more than 20 years, he worked for the Opto-Mechanical Association LOMO in Russia. He was promoted from an engineer to the head of the design bureau of complex instrument making. He has published more than 70 patents and more than 50 scientific articles. Currently, he works for the project Labor-Microscopes. His primary field is microscopy, especially the development of light microscopes and accessories; the design of optical systems of microscope objectives is his main professional skill. He has made more than 350 types of optical desig for microscope objecrtives.
