We¹ve also been having this exact problem (and on our Leica SP5). The 20x
0.7 multi-immersion lens doesn¹t have a long enough working distance. We
it doesn¹t get us all of the way through. I¹d love to try out a 20x/0.95
lens with the 2.5mm working distance, but we don¹t have one. I¹ve already
is getting one. I really think that is the best thing for spheroids in
collagen gels. In the mean time, if anyone has spec prep thoughts for
thoughts.
