This paper describes a method of determining the decentering of an aspheric surface relative to the geometrical center of an astronomical mirror by means of a three-point linear spherometer, also used to determine deviations of the profile of a ground surface from the specified surface. Examples are given of the successful use of the device. © 2015 Optical Society of America. Source

This paper describes a method for determining the absolute profile of the ground aspheric surface of large astronomical mirrors, using a linear three-point spherometer successively displaced perpendicular to the direction from the center to the edge of the item, as well as a method for determining the vertex radius. Examples are given of the successful use of these methods. © 2015 Optical Society of America. Source

A recent development among next-generation microscopes that use zoom systems to smoothly vary the magnification was the MBS-14 stereoscopic zoom microscope. This article lists its characteristics and optical layout, the optical layout of the eyepiece, and a description of the zoom system, with a graph of the law of motion of its movable components, as well as a list and description of the accessories of the microscope. © 2013 Optical Society of America.

A small-capacity technology for producing various types of electrovacuum glasses has been developed. The manufacture of S48-3 high-temperature glass involved the most complex technology. After investigating various methods of decolorizing this type of glass, the evacuation method was chosen. © 2013 Optical Society of America. Source
