Universal (for standard filter doors)
Turn your microscope into a 'phase contrast' microscope in an instant with this ingenious, low-cost system! You'll be able to observe incredible details on small or large objects such as: foramminifera, mosquito heads, pollens, crystals or even plant sections.

It is placed in the filter holder (for standard filters) of the microscopes in order to make an observation on a dark background. The illumination being lateral, more details as well as the volume of the object are highlighted (works at magnifications x4 and x10). The gain in observation quality is incomparable.
