Hi @HamishC,
A few options from a search of the forum:
- This one looks to be almost identical to the system you’ve pictured
- This uses an extended T-slot rail, with some wide lighting
- This looks to be a similar-ish housing, but isn’t explicitly about stereo vision
- Internal stereo cameras could also be an option, albeit with reduced stereo depth range
- There may be some other insights by searching the forum for photogrammetry and the like
