If you have an eyepiece magnification of 10x and an objective magnification of 4x, what is the total magnification? If you have an eyepiece magnification of 10x and an objective magnification of 10x, what is the total magnification?

What is the diameter of the field of view (ie. Diameter2) when the total magnification is 100X? Report your answer in µm

What is the proper method of cleaning the microscope? Select an answer. a. Change the magnification to the lowest power, clean the objective lens and ocular lens with lens paper b. Change the magnification to the highest power, clean the objective lens and ocular lens with lens paper c. Change the magnification to the lowest power, clean the objective lens and ocular lens with a paper towel

The compound (bright-field) microscope is parfocal. It means that:   Question 4 options:   objective lenses are built into revolving nosepiece   its lenses effectively decrease focal lenght   can achieve maximum resolution lower than 0.2 μm   image should remain in focus when objective lens is changed

Ocular Lens: 10x Ocular Lens: 10x Objective Lens: 4x Objective Lens: 100x А B

Why do you use immersion oil with 100X objective lens?

Why is it not irecommended to start with high dry or oil immersion lenses

Adjusting the objective aperture is an important step to obtain phase contrast in TEM. Compare the differences in objective aperture operation between diffraction contrast and phase contrast.
