This subpage is devoted to Polish camera tubes- Polish vidicons. In Poland, vidicons were initially produced by the Industrial Institute of Electronics (PIE), from the beginning of the 1960s. The institute was located at Długa 44/50 in Warsaw. Vidicons manufactured by PIE have a distinctive PIE logo badge in an octagon. Over the years, the Industrial Institute of Electronics was reorganized, and in the years 1972-1977 OBREP (Research and Development Center for Vacuum Electronics) was separated from this institute. In 1977, OBREP was transformed into OBRTT (Research and Development Center for Television Technology). However, this name did not last long either. In the years 1980-1984, OBRPO (Image Converters Research and Development Center) was active. In 1984, the old name OBREP was returned, which had survived until 1993. It was in that year that ITP (Institute of Vacuum Technology) was established, which operated until 2002. In 2002, ITP was included in the PIE. There are also images with the imprint "Unitra OBREP" - these images come from the 1970s and with the imprint or a sticker "Unitra Polkolor", because at one time OBREP was subordinated to Polkolor. "OBREP" -Research and Development Center for Vacuum Electronics operated under this name in the years 1972-1977 and in the years 1984-1993 and was located in the same place as PIE. In the 1970s, the production of vidicons was started by the "Unitra-Dolam" plant in Wrocław, using some of the components used in cathode ray tubes for their production. As it was possible to establish, the following types of widicons were produced: PWM2, PWM21, PWM3, PWF3, PWM4, PWM6, PWM7, PWM35, PWM40A, PWM41A, XWM7. It is possible that other types were also produced.
