Another great collab with @henriqueslab.bsky.social, congrats @afonsomendes92.bsky.social et al 🙏

Yes it needs the corresponding Zeiss tube lens. Part no 423731-8246-000.

We are excited to share our development of a new 10X lens with NA=0.50 over a 7.2 mm FOV and a 35 mm working distance (water), fully corrected from 400-850 nm. This lens will power our upcoming ExA-SPIM "2" and is available for dissemination - please get in touch if interested!
