CR137 DRY Darkfield Condenser for 4X-40X

Features

Darkfield microscopy uses refracted light to make live, unstained specimens appear with bright contrast against a dark background. By blocking the center of the brightfield of light and not allowing direct rays to enter the objective, only the outer oblique rays of light strike the specimen. This DRY darkfield condenser is a more economical choice and easier to use than the OIL darkfield condenser, but the contrast will not be as sharp. Remember, darkfield will not work with a standard 100x objective because of the high numerical aperture, but the optional 100x Darkfield objective features a built-in IRIS for easy darkfield viewing.
