Lighting setting features of opto-electronic measuring system for controlling adhesive joints optical components

Markina O. N.

Journal of Achievements in Materials and Manufacturing Engineering

2017

Vol. 84, nr 2

49--57

Purpose: The purpose of this article is to study the features of setting and selecting the source of illumination of the optoelectronic measuring system for the control of adhesive joints of optical parts. Design/methodology/approach: The research and analysis of the lighting characteristics of halogen and LED lamps, used as a source of illumination in the measuring system, was carried out. Findings: In the course of experimental studies, the sensitivity and resolution of fixing defects of adhesive joints of optical parts were increased and the measurement error was reduced from 10 ± 1.2 microns to 10 ± 0.3 microns. Research limitations/implications: The limitations of the accuracy of the measurement are 10 ± 0.3 microns of adhesive defects, since the studies were conducted on separate samples of glues that did not cover all adhesives for the connection of optical surfaces and the thickness of glass surfaces was 1 mm and 2 mm. Practical implications: With the application of the lighting system approach described in the article, it is possible to improve any optoelectronic measuring system, thereby increasing the accuracy of the measurement. Originality/value: The originality of the results of the article is the experimental data of the studies of light-technical characteristics of the halogen lamp, which is used in the optoelectronic measuring system.
