The substrate ... Low expansion LK5 - Russion equivalent to PYREX - this material has an excellent thermal behaviour. LK5 blanks are very homogenous and they are used for a long time to make quality mirrors.

Fast cool-down ... the low thermal expansion rate will be assisted by the low thickness of the mirror which enable a short cool-down period, typically about 50% of the time for full thickness mirrors to reach thermal equilibrium. Hence the telescope is quicker ready to go for observation and photography.
