The Nema Imager is a spacing-saving and versatile imaging station. It's easy to use and more affordable compared to a traditional inverted microscopes. It’s best suited for:

  • Easy integration into optogenetic and calcium imaging experiments
  • Live imaging and high frame-rate recording of freely moving worms in microfluidic devices.
  • High-quality images of worms immobilized on agar pads, with glue, or in hydrogel.
  • Imaging of fluorophores in the green family (GFP, GCaMP, etc.), configurable to provide three color detection of blue, green and red fluorophores.
  • Phase contrast images of internal structures.

To scale, the Nema Imager (right) next to a traditional inverted microscope (left).

Key Features:

• Low and high power, long working distance objectives allow for imaging of small structures.

• The large microscope deck is tapped with ¼-20 thru holes for maximum versatility to mount additional accessories.
