Question
What is the difference between CLN-Cxxxxxx-HSLL and DMLN-Cxxxxx-HSLL?
e.g. CLN-C10F5FS-HSLL vs DMLN-C10F05-HSLL
Answer
There is no difference except NIR sensitivity. Both are the high speed liquid lenses which are used for DataMan370/470/390 series. The only difference between the two lenses is that DMLN lenses have a built-in IR Blocking Filter and the CLN lenses do not have this filter.
