Professional oil usage methods and their importance for microscopes
In the maintenance of microscopes, it is necessary to choose the right oil for maintenance. Generally, cedar oil is commonly used. Of course, many microscope manufacturers now produce another non resin synthetic immersion oil, which can provide a non resin synthetic immersion oil with a refractive index of 1.515-1.518 and suitable dispersion characteristics. Due to its good characteristics and suitability for high-quality oil immersion work, Currently, it has gradually replaced the two resin based immersion oils mentioned above.
So how to use the mirror oil of a microscope? Microscope oil immersion should be used sparingly, not too much, just one drop is enough. Dropping too much oil into the microscope is not beneficial, but it can become more greasy, easily infected with dust, and cause a lot of trouble for cleaning the objective lens after use. When dripping lens oil, it is usually at the end of the observation. Even when using non resin based immersion oil, the objective lens and cover glass should be carefully cleaned. First, use dry lens wiping paper or cloth to wipe off the immersion oil, and then use lens wiping paper or cloth dipped in xylene or gasoline to wipe off the remaining immersion oil. (Recommended reading: How to troubleshoot a microscope?) If a collector is used for immersion, the top of the collector and the bottom surface of the slide should also be cleaned. When using immersion oil, attention should also be paid not to mix fresh immersion oil with immersion oil that has been stored for a long time, otherwise it will form dark lines and significantly affect the quality of the image.
The above is an introduction to the importance and usage precautions of microscope specific oil for microscopes. In short, whether it is daily maintenance of microscopes or troubleshooting, microscope specific oil is an indispensable item.
