Features:
oil refers to oil objective lens, 100x objective lens has high magnification and small aperture. Cedar oil is needed when using it. The light is transmitted in oil to reduce light loss, so as to enhance the brightness of the field of view and make the image clear.
Elastic objective lens: 4X, 10-X, 20X, 40X, 60X, 100X elastic objective lens, which ensures that the specimen will not be damaged when viewing.
Low-power objective lens has a larger aperture, brighter imaging, and a large field of view. High-power objective lens has a smaller aperture and significant magnification ability. The field of view and brightness are reduced, and it takes time to find the image.
It is suitable for various types of biological microscopes with original objective lenses of 185 and 195.
