How does an oil lens differ from a normal objective lens in terms of how it is used?
When using the oil lens, you need to drop a drop of cedar oil on the glass slide, and the oil drop cannot be separated from the objective lens during its ascent. Moreover, the magnification of the oil lens is larger than that of the ordinary objective lens.
When using oil lenses, you should pay attention to:
1. After using the oil lens, first use lens cleaning paper dipped in a little xylene to wipe off the cedar oil on the lens and specimen, and then wipe it clean with dry lens tissue. After adding cedar oil, the field of view becomes obviously darker. You need to raise the light collector to the highest position and open the aperture to the maximum. Before using the oil lens, the target observed through the low-power lens and the high-power lens must be in the center of the field of view.
2. Cedar oil is a special oil for oil lenses. Dropping a liquid with a refractive index of 1.5 under the 100x oil lens can significantly increase the resolution of the oil lens and improve the observation effect of the microscope. The refractive index of cedar oil is 1.52, which is the Good microscope oil lenses use oil.
3. When using a microscope oil lens, the microscope must be upright on the table. The arms must not be bent to tilt the stage to prevent the cedar oil from overflowing, affecting observation and contaminating the table.
Can optical microscope lenses be cleaned with cedar oil?
OK. Turn the light to its maximum intensity (concentrator raised, aperture fully open). Turn the coarse adjuster to raise the lens barrel, and put 1 small drop of cedar oil or paraffin oil (not too much, do not spread it) on the specimen directly below the objective lens.
