Balzers Filter

[eams]

Hello,

Is there anyone familiar with the Balzers filters and can tell me the meaning of the following codes?
LCS40-550-S
LCS10-400-S
CVI F40-600-4 BSU 8-4

I can imagine that 440 550 and 600 are the wavelengths but further I have no idea and I appreciate if somebody can help me.

Thanking you in advance,

Eddy Seyfarth
