How important is the special lens oil for scanning electron microscopes? Special lens oil for microscopes is very commonly used in the maintenance of microscopes, so how important is the use of this special oil for microscopes? What is the importance?

In the maintenance of the microscope, the oil must be selected to maintain the microscope. Generally, cedar oil is commonly used. Of course, many microscope manufacturers now produce another non-resin synthetic immersion oil, which can provide a 1.515- The non-resin synthetic immersion oil with a refractive index of 1.518 and suitable dispersion characteristics has gradually replaced the above two resin immersion oils due to its good characteristics and suitability for high-quality scanning electron microscope oil immersion work.

So how to use microscope lens oil? The microscope immersion oil should be used sparingly, and it does not need a lot. Just one drop is enough. Too much lens oil is not good for the microscope. On the contrary, it will be more greasy and easy to be infected with dust, and it will wipe the objective lens after use. Cause a lot of trouble.

When the lens oil is dripped, it is usually at the end of the observation. Even if the non-resin immersion oil is used, the objective lens and the cover glass must be carefully wiped. First, wipe off the immersion oil with dry lens tissue or a dry cloth, and then use Wipe off the remaining immersion oil with lens cleaning paper or cloth dipped in xylene or gasoline. If a light collector is used for infiltration, the top of the light collector and the lower surface of the slide should also be cleaned.

When using the immersion oil, be careful not to mix the fresh immersion oil into the immersion oil that has been stored for a long time, otherwise it will form dark lines and obviously affect the image quality.
