I am positive that "Aeroflot" wasn't treated as a generic word for an airline, but I wasn't much of an amateur photographer in the Soviet era, so can't be sure whether Rubinar made the grade. What makes me doubt this is that despite Rubinar being the only photographic lens of the type, mirror lenses were (and are) widely used in telescopes, named differently. | |

"Aeroflot" may not be a generic Russian language word for airline, but in the USSR, there was only one Soviet based airline and it was Aeroflot, so Aeroflot was THE Russian airline. Similarly, Rubinar was THE Soviet mirror lens. | |
