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
9 B6 @8 d$ j& y; A# z8 X  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.

These were just 2 of many filter glasses that Corning sold until the
1990's. The business was sold to Kopp Glass of Pittsburgh, PA. I have a
Kopp Filter Glass catalog that shows these filters have been produced by
Kopp. They have their own catalog numbers for them (CS-Number 7-56 =
Code 2540 & CS-Number 2-59 = Code 2404) , but they also maintain the
* k% r: U% r/ {) |, {/ _Corning glass code numbers as well for each specific filter glass.
