MicroProbe Objectives

Blood vessels (red) and enterocytes (green) imaged using a 20X MicroProbe objective inserted within a small incision in the wall of the jejunum. Image captured by Dr. Herlen Alencar, Massachusetts General Hospital, Boston.

Minimally invasive, high-resolution
imaging deep within live animals

  • True lens technology, not GRIN lenses, these objectives have slim diameter tips of 1.3mm (6X and 20X) and 3.5mm (27X), all with working distance of 200 microns.
  • Allows observation of various fluorescence signatures where standard objectives cannot reach.
  • Transmission and chromatic correction throughout visible and near-infrared (NIR) spectra (450-1000nm) provide excellent image quality.
