Symbiosis or Parasitism
Note: The early Ergonom microscopes (mainly the Ergonom 400) used to make this documentary, have now been replaced by the Ergonom 4000 series which has comparable and enhanced capabilities. All images are made in real time and natural colors without staining or oil immersion. Due to the extended working distance, the objective does not actually touch the slide at any time (max. NA 0.95).
Most microscope images in this film, with resolution of 200nm or greater, could have also been made with the Ergonom 3000 series of microscopes. Like the Ergonom 4000, the 3000 series also features enhanced DOF and full color contrast without the need for staining or oil immersion.
