Description
Zhemchung-4 lens van Yantar-2K Soviët spionage satelliet (UNIEK!)
Lens - Good (used & in working condition with visible signs of use)

This concerns a lens carried by a YANTAR-2K (Fenix) satellite of the Soviet Union. The Yantar project started in 1964 to replace the Zenith satellite. The Yantar satellite was used for espionage during the Cold War.

Thirty Yantar-2K satellites have been launched, each with a flying time of thirty days. Two launches failed, amongst others, the ‘Fenix no. 1’.

It consisted of three parts, of which one, the ‘landing and camera system module OSA’ was recuperated and could be recycled three times. The camera system that was in the OSA was titled ‘Zhemchung 4’ and this is what this lens was used in.

This lens was used three times and was sent for storage afterwards.

The case is 66 x 66 x 147 cm and the lens has a 42 cm diameter, a 132 cm length. It weighs 158 kilograms. The combined weight of lens and case is 188 kilograms.

The lens consists of various parts. The front part has a 40 cm diameter and the last has a 23 cm diameter. It contains three collimator modules. The middle has a diaphragm that can be adjusted with the use of the red rotary knob.

All pictured in the photos and documents.
