Micron's Dark Field Attachment is a specialized optical accessory designed to enhance the contrast of unstained, transparent specimens. Dark field microscopy works by illuminating the specimen with a hollow cone of light, causing only the light scattered by the specimen to enter the objective. This results in a bright specimen appearing against a dark, almost black background. This technique is widely considered one of the best methods for observing live, unstained microorganisms and fine details in transparent materials. This attachment is designed to be easily fitted to a standard brightfield microscope, typically by replacing the standard Abbe condenser. The dark field attachment creates the hollow cone of light necessary for the technique. This is one of the best and most cost-effective ways to add dark field capability to an existing laboratory microscope.
