What is the effect of immersion oil on the microscope
A microscope is a high-precision observation instrument that is often used to observe food that is considered invisible to the naked eye. Commonly used microscopes include tool microscopes, biological microscopes, metallographic microscopes, electron microscopes, etc. As a frequently used instrument, its maintenance is the top priority. The following editor will explain to you how to maintain the microscope.
In the maintenance of microscopes, the choice of oil is very important for microscopes. Generally, cedar oil is commonly used, but the effect of cedar oil is not very good, so many microscope manufacturers began to produce and use another non-resin synthetic immersion oil. It 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, it has gradually replaced the above two resin immersion oils.
When dripping lens oil, generally after the observation is over, even if non-resin immersion oil is used, carefully wipe the objective lens and cover glass. First use a clean lens cleaning paper or a dry cloth to wipe off the immersion oil, and then use a lens cleaning paper or cloth dipped in xylene or gasoline to wipe off the remaining immersion oil. If a collector dip is used, also wipe the top of the collector and the underside of the slide.
When using immersion oil, care should also be taken not to mix fresh immersion oil into the immersion oil that has been placed for a long time, otherwise dark lines will be formed and the quality of microscope imaging will be significantly affected.
