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,
$ z- p6 U1 J7 G( jvisible absorbing optical filter. Transmission for a 2.3mm glass was 57%
at 1000nm, and only ~ 20% at 900nm.

Code 2404 was a Soda zinc borosilicate glass sharp cut infrared
transmitting filter, with the visible 50% transmission edge cut at ~
# D; R$ d; }8 \& i630nm (3 mm thick glass). There is essentially no transmission below ~
/ K5 m. A5 o6 T" y585nm for the 3mm thickness.

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

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
