There were no Soviet front-loading washing machines.
Well, there was one, but it was a licensed copy of Italian Merloni (now Indesit), so probably no |

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. |

The first version was Zenit 2 (there was no Zenit 1) and it carried an SA-10 camera, an SA-20 camera, a Kust 12M electronic intelligence gathering radio package as well as the Baikal photo-television device. Following the poor performance of the Baikal device, the Ftor-2P package was installed, which incorporated the camera equipment and provided 60x60km images with a resolution of 10 to 15m.
The Zenit 4MKT version, also known as Fram, carried the Priroda 3 Earth resources camera system which took multi-spectral photographs on black and white and spectro-zonal film with a resolution of 20 to 30m. |

Zhemchug-4 lens – a lens sent into space in the Soviet Union’s Yantar-2K spy satellites, which were used from the mid 1970s until the later years of the Cold War.
The Zemchug-4 comes in its original storage case. It measures 4.5ft long and around 1.5ft wide and – bear this in mind if you’re planning to take it up the stairs – weighs in at 348lb (158kg). The focal length is believed to be between 3000mm and 4000mm. |

The refractive index of air and vacuum are nearly the same. Vacuum exact 1. Air about 1.000292.
I think I read in lens design books or workshops that difference normaly does not matter.
The usability is mainly limited due to the weight, but remember that Zeiss 1700mm f/4 lens. This is more or less a longer focal version of that _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

Pure water has a refractive index if 1.333 so the difference is only a little more than 1000x greater |

According to this Wikipedia it is estimated to have 3 to 4 meter focal length, so quite a slow lens with ~f/7.5 to 10.
It is possible, that the lens is very highly corrected, but I suppose the camera is not a multichannel one with extra infrared channel. As with the Zeiss Pinatar lens it could be that some special glass materials are not used due to shock, vibration, thermal considerations, so a more complex setup with more stable glass.
For very high end lenses the refractive index of the used glass is determined with that accuracy of the refractive indexes given above.
But still I think the refractive index difference will be likely less a problem than for example the use today with different film material or adaption issues.

Interesting news there - seems the complete camera with lens normally reenters into the orbit to be reused! So there could be several of this lenses in used state around _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html
