MiniXL — Miniscope Extra Large FOV

The MiniXL is the second generation of the MiniLFOV, a large field-of-view miniature microscope for imaging neuronal activity in freely moving mice and larger animals. It supports deep brain imaging using implanted optical probes and cortical imaging through cranial windows.

Features

  • 3.5 mm field of view
  • ~3 um resolution
  • 1.9 mm working distance
  • +/-200 um electronic focal adjustment
  • Modular, achromatic optics
  • 3.5 grams
  • 30 mm tall
  • Absolute head orientation sensor
  • Single coaxial cable (down to 0.3 mm diameter) for power, communication, and data
  • No soldering required
