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,
7 A" g* t# b2 K8 fvisible absorbing optical filter. Transmission for a 2.3mm glass was 57%
at 1000nm, and only ~ 20% at 900nm.

6 T: d: B, A: t+ h: n; MCode 2404 was a Soda zinc borosilicate glass sharp cut infrared
; U0 q- s/ I- p$ r' ttransmitting filter, with the visible 50% transmission edge cut at ~
630nm (3 mm thick glass). There is essentially no transmission below ~
585nm 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
