At one point, LeRC got a movie from HQ that the Soviet Embassy had sent around. It showed a launch at Baikonur, and I noticed everyone there was wearing a Plantronics MS-50 or knockoff there of... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

Probably Canada Resin #39 in '72. Polycarbonate optical lenses were introduced in about '83 and became more mainstream by the mid '90s. They are a great lens with refractive index of 1.59 (compared to 1.50 in glass or CR39), but they still have a little more chromatic dispersion ie a lower Abbe number. And you now can't buy glass at all, I'm told. There's a new fracture requirement or such.... I'd have thought this to be the "blind-in-an-hour" vender BS, but a friend looked into it, found it to be true and also found a workaround: the military gets some glasses that are still glass. Short sleeve shirts and ties were OK until Sipowitz checked out... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |

Well, no one mentioned the big sideburns... the decor is General Services
Administration metal. Looks like a couple of teletypes next to the wall for communicating with the Parks antenna or range safety, something.... old fashioned headphones ... and oh yeah noticed that they are muddling through without a lot of cultural diversity, which had not been discovered at the time of the photo. Well I'll be damned.... there is a girl sitting behind the guy with the light colored jacket. |

Sort of curious....I wonder who is the mad monk at 9 o'clock? Bearded

Glass lenses are heavy, they break if you drop them, and if they are hardened the impact resistance increases - but when they do break there's glass powder exploded into your cornea... not fun. Also a small scratch or defect can cause the hardened lens to spontaneously shatter... most people get really ****ed off if that happens.. And the hard-coated plastics have scratch resistance comparable to glass anyway. - Peter |

And the hard-coated plastics have scratch resistance comparable to glass anyway. You can still get glass, but the requirements for how thin the center of the lens can be have been increased, so a lot of folks with higher sphere prescriptions either need to go to a high index glass and pay $500/lens or go to plastic. I strongly recommend the Zeiss high index glass lenses. They have much less birefringence than any of the plastic lenses I have ever used. --scott -- "C'est un Nagra.
