大家好，有谁能帮我翻译下面这段话，是关于光学玻璃材料参数的内容
  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.

transmitting filter, with the visible 50% transmission edge cut at ~
630nm (3 mm thick glass). There is essentially no transmission below ~

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

Kopp. They have their own catalog numbers for them (CS-Number 7-56 =
