  • searching for some glass data sheets

    From Michael Koch@21:1/5 to All on Wed Dec 23 02:59:05 2020
    Hello,

    I just got a huge collection of optical glasses. They are all from Schott. For 95% I did already find the data sheets, but a few are really difficult to find:

    LgSK2 (it's listed in the 1989 price list)
    PK51 (I did already find the N-PK51 data sheet)
    SFN64 (it's listed in the 1989 price list, I did already find the SF64 data sheet)
    SSK5 (I did already find the N-SSK5 data sheet)
    UK50 (it's listed in the 1989 price list just below "K50")
    ZK7 (I did already find the ZKN7 data sheet)

    I'm looking for the full data sheets which also lists the infrared refraction indices.

    Thanks,
    Michael

    I don't have anything earlier than about 2006, which was after the Great Unleading.

    I just got the LgSK2 data sheet. Still searching for the other five.

    I just got three more data sheets. Only SSK5 and ZK7 are still missing.

    The N-series are the newer Pb- and As-free versions.

    NZK7 != ZK7, NBK7 != BK7.

    It's even more complicated:
    N-ZK7 != ZKN7 != ZK7
