Darkfield microscopy is a very simple method for viewing unstained specimens clearly because it is clearly visible. Good candidates for darkfield observation usually have a transparent background that way the light an illuminate the specimen and darken the surrounding area, making the image quality clearer and more intense. Good specimens to use include aquatic organisms, cells, and cultures.
To achieve good darkfield images make sure that the central light rays along the optical axis are blocked. Blocking these light rays allows for just oblique rays to pass through at sharp angles, striking the specimen and illuminating the image. A darkfield condenser will get you the results your looking for with your microscope. The condenser reflects a single surface that provide more even illumination.
We recommend the OMAX Compound Binocular Microscope with Darkfield Condenser and 5.0 MP Digital Camera for $549.99
