The Mini2P-Collection Fiber v1 serves as a crucial component within the Mini2P miniscope setup. The Mini2P is a 2-photon miniscope for large-scale calcium imaging in freely moving mice. The Mini2P can obtain stable simultaneous recordings of over a thousand cells across multiple planes in densely active cortical regions, even during various behavioral tasks.


The Mini2P-Collection Fiber v1 guides emitted light from the scope back to the detectors. It comprises numerous independent fine fibers bundled in a thin sheet. The collection fiber is exceptionally soft and is equipped with anti-reflectance windows at both ends, along with a grin lens at the scope's side. The detector side is fitted with an SMA connector. The fiber sheet is coated with a thin layer of black rubber to enhance stray light segregation. Each Mini2P-Collection Fiber v1 passes a quality control process following the Mini2P team's quality criteria: more than 80% photon pass-through and less than 3 dead cores.
