No.
No, it is best to clean the oil from the 100x objective lens using lens paper or a clean cloth specifically made for cleaning lenses before putting the microscope away. Leaving oil on the lens can attract dust and debris, leading to a blurry image and potentially damaging the lens.
40x , 100x , 400x
The most satisfactory way to study bacterial morphology 40x objective.
Because the objective touches the lens.
yes it is.
the compound microscope generally have three tye of objectives power lens as 10X, 45X, & 100X.
It would depend on the microscope, however, there are usually 3 different powered objective lenses on a light microscope, the lowest being of 10x magnification, the middle being of 40/45x magnification, and the highest being of 100x magnification.
In microbiology, the most commonly used objective on a microscope is 100x. This is because this is the closest yet detailed magnification where you can see a specimen. Higher magnifications lead to a closer look but less detail.
The oil immersion lens @100x
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000
Using a 10X eyepiece, a student would need to use a 10X objective to have a final 100X magnification. 10 X 10 = 100X
...LPO is the 100x power...
Used in conjunction with the eyepiece lens, the objective lens is what gives an optical microscope its ability to produce magnified images. There are normally three to four objective lenses on microscopes, ranging from 4X to 100X magnification, where the stronger lenses are larger. When coupled with the eyepiece lens, the magnification of a microscope ranges from 40X-1000X, though special conditions are required to achieve a sharp image at 1000X magnification.
