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 X: ]/ l7 _' _  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.

Code 2404 was a Soda zinc borosilicate glass sharp cut infrared
transmitting filter, with the visible 50% transmission edge cut at ~
630nm (3 mm thick glass). There is essentially no transmission below ~
4 }+ k3 z* e+ u/ `585nm for the 3mm thickness.

Corning glass code numbers as well for each specific filter glass.
