Our miniature fluorescence microscope uses wide-field fluorescence imaging to record neural activity and network structure in awake, freely behavin mice. The functional design of our microscope is similar to a table top wide-field fluorescence microscope with the following key differences:

  • All nonessential components are removed
  • The table top objective is replaced with an imaging objective GRadient Index of Refraction (GRIN) lens
  • The excitation light source is a super bright LED rather than a lamp or laser
  • The optical filters and dichroic mirror are custom cut to minimize their size and weight
  • A small CMOS imaging sensor is used to record emission light instead of a large CCD, emCCD, or sCMOS camera
  • Adjustment of focal plane is done by moving imaging sensor not objective
