The problem of increasing the conversion coefficient of two-chamber electro-optical converters used in the night vision technique has been considered. The results of the study on the influence of the vacuum processing technology for both chambers of the given products on their amplifying ability have been given. The methods have been proposed for increasing the level of conversion by changing the temperature-time mode of processing the photocathode of the first chamber of the device, as well as optimizing the sputtering of chromium on the mica substrate of the cathode of the second chamber. During the research, instrumental, expert and statistical analysis the non-destructive and destructive technological control have been used. As a result, an increase of the yield of products in terms of the conversion rate has become 35 %, an increase of the average value of η has become 65 %.
