Highest Optical glass Manufacturer Quality

From our experience that they have different characteristics:

  • Schott BK7: we think you know BK7 very well, as BK7 has best transmittance rate, but the price is high.For optic polished of all optic parts
  • Ohara S-BSL7: it can be equilvalent to N-BK7 due to same transmittance rate with BK7, for polished part for both windows, plates also prism.
    and S-BSL7 price advantage comparing with BK7
  • Chinese K9 : this material can replace polished BK7 plate and windows with thinner thickness. It can not used for optical prisms. And this K9 glass has a very competitive price. this is very special.

    We suggest you can make trial order for these three optical glass wafer to test it. The price gap will be much attractive.
