It is well suited for uses involving live and unstained biological samples such as a smear from a tissue culture or. Dark field Microscopy also known as dark field illumination is a method that uses microscopes to make a specimen appear bright white. Specimens with a different refractive index or refractive index gradients from their surrounding. As the name implies the background is dark and the.

Dark-field microscopy is ideally used to illuminate unstained samples causing them to appear brightly lit against a dark background. Dark field microscopy is a method which also creates contrast between the object and the surrounding field. A dark field microscopy is used to examine live micro- organisms that either invisible in the ordinary light microscope cannot be stained by. Ad Find What Youre Looking For Fast.
