Surgery for two lenses system

[Lee Hyeonju]

Hi everyone,

I have a question about two lenses system.
now my lab try to see deep brain region, so we will order 0.6mm(diameter) X 7.3mm(length) lens from inscopix.

I didn't do any surgery with thin lens, But I cannot imagine that no-gap between objective lens of my miniscope and thin lens.

Is there any tips or caution for this surgery?
