Large LFOV miniscope different field of view

[Xueting-Sun]

hello，dear：
Thanks for all the sources you support.
Rrecently， we assembled the large LFOV based on the information in the open source files. However, after the assembly, we found that the working distance is greater than 3.5mm(＞4mm), similarly, the field of view is greater than 3.62.7mm (4.23.2). I assembled them the way in the literature。https://www.biorxiv.org/content/10.1101/2021.11.21.469394v1
I have no idea how this happened.
Thanks for your help.
Best!
