If the specimen is too dark for proper analysis, you can try diluting it with a suitable solvent or using a lighter stain to enhance visibility. Adjusting the microscope settings, such as increasing the light intensity or changing the condenser position, can also help improve the clarity of the image. If these adjustments do not work, consider preparing a new specimen with a more appropriate concentration.
A light microscope that makes the specimen appear light on a dark background is called a darkfield microscope. Darkfield microscopy illuminates the specimen with oblique light, making it stand out against the dark background, which enhances contrast and visibility of transparent or low-contrast samples.

Specimen collection can be identified by labeling each specimen with patient information, date and time of collection, and type of specimen. The specimen should be collected using proper techniques, stored in appropriate containers, and transported to the lab in a timely manner to maintain specimen integrity. Accurate documentation of the entire collection process is important for proper identification.
When preparing a wet mount specimen for viewing, it should be covered with a coverslip. This thin piece of glass or plastic helps to flatten the specimen, prevent contamination, and protect the microscope's lenses. Care should be taken to lower the coverslip at an angle to avoid trapping air bubbles.

Dark field microscopy illuminates the specimen from the side, causing light to scatter off the specimen and appear bright against a dark background. Light field microscopy illuminates the specimen from below, causing light to pass through the specimen and appear dark against a bright background.
Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.
Dark field lighting in microscopy can be effectively used to enhance contrast and highlight specific features of a specimen by illuminating the specimen from the side, causing light to scatter off the specimen and only enter the lens if it is reflected by the specimen. This technique creates a bright image of the specimen against a dark background, making it easier to see fine details and structures that may not be visible with traditional bright field lighting.
A Dark Field microscope is one that has a special condensor (light source) that illuminates the specimen in such a way as to enhance the contrast even if it is unstained. When you look at a specimen in a dark field scope, it looks bright, but it is visible against a black background -- the 'dark field.'

If the film is too dark, the xray needs to be retaken with lower kV and mAS settings. Xrays that are only marginally too dark can be looked at under a bright light.

The specimen should be placed on the top surface of the microscope slide. This allows the light to pass through the specimen from below and be magnified by the lenses in the microscope to form an image for observation.
If a specimen spills on your clothes, you should immediately remove the contaminated clothing and wash the affected area with soap and water. Be sure to follow any specific handling instructions for the type of specimen involved and seek medical advice if needed.
