Mightex · OASIS systems
Fiber-bundle in vivo imaging and stimulation system for freely behaving animals: lightweight head mounts (about 0.7 g), up to 7 regions or animals per system, and Polygon integration for cellular-resolution optogenetics.
Manufactured by Mightex. Precisometer is a Mightex distribution partner: we quote, integrate and support Mightex products, with in-person support in the Netherlands and Belgium.
Based on: Mightex OASIS Fiberscope and OASIS accessories pages.

From Mightex
The OASIS Fiberscope relays the image from an implanted GRIN lens through a flexible imaging fiber bundle to a benchtop optical unit, so all optics and electronics stay off the animal. The head mount is a mechanical interface only, which keeps it light and allows water-based assays and MRI-compatible options.
Branched imaging fibers record and stimulate up to 7 regions or animals at once. Excitation sources, filter sets, cameras and fiber bundles are interchangeable, and a Polygon pattern illuminator can be added for spatially targeted optogenetics. PolyScan and the PolyEcho I/O module synchronise imaging, stimulation and behaviour.
Mightex offers three formats: the standard Fiberscope; ROAM, which compensates rotation so the imaging fiber can turn 360° with a stable field of view; and a Large FOV version that extends the field to 3.2 mm, for example for cranial-window imaging.

Ordering and integration
Imaging fiber bundles between the head mount and the base unit.
Implanted GRIN lenses relay the image from deep tissue to the fiber.
Fibermounts, focusing fixtures and illuminators.
Event-driven TTL and analog synchronisation with unified timestamps.
PolyScan4 controls the Polygon, light sources and cameras; Mightex includes it with the Polygon.
