Accessories for Mini2P - Coupling Box v1

Founding developers Edvard Moser, May-Britt Moser, and Weijian Zong

Edvard Moser and May-Britt Moser lead the Kavli Institute for Systems Neuroscience in Trondheim, Norway. In 2014 they received the Nobel Prize in Physiology or Medicine.

Weijian Zong is a researcher at the Kavli Institute for Systems neuroscience where his main research interests are bio-imaging, neuroscience, neuronal computation.

The Mini2P is a 2-photon miniscope for large-scale calcium imaging in freely moving mice. It enables stable simultaneous recordings of over a thousand cells across multiple planes of densely active cortical regions during a wide range of behavioral tasks without affecting the animal's behavior.


The Coupling Box is the component between the laser and the excitation fiber going to the Mini2P miniscope. It pre-chirps the laser pulses and facilitates effective coupling into the excitation fiber. The Coupling Box accepts the free-air laser beam and outputs the laser via an SM05 thread. The fiber-bound coupling holder and coupling protector attach easily to the Coupling Box. This Coupling Box is compatible with all related Mini2P parts based on the original design.


  • The box comes tested, with an aligned laser path
  • Includes the new higher-dispersion Dielectric prism
  • Includes 3 pre-chirping rods
  • Includes a ½ wave plate for polarization adjustments
  • 2 prisms can be adjusted in 2-axis to finely tune the laser path


  • Coupling Box with lid
  • 3 dispersion glass rods
  • Half-wave plate in a rotatable mount
  • 8 higher-dispersion dielectric prisms
  • 2 adjustable prism mounts
  • Adjustable fiberport to receive 'Mini2P – Exitation Fiber v1'


Shipped 8-10 weeks after order is received.
