大家好,，有誰能幫我翻譯下面這段話,，是關(guān)于光學玻璃材料參數(shù)的內(nèi)容
  Code 2540 was a soda lime silicate glass based infrared transmitting,
visible absorbing optical filter. Transmission for a 2.3mm glass was 57%
at 1000nm, and only ~ 20% at 900nm.

We do have much of the details on these glasses in the REMIS database of
properties, as well as composition information from the released
