What objective focuses closest to the slides?
The oil immersion lens @100x
Which objective focuses closest to the slide when it is in focus?
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
What mirror is used for oil immersion?
100x lens is used with oil immersion
Which objectives focuses closest to the slide?
oil immersion
Why don't microscope makers use 100x ocular lenses?
Why don't micorscope makers use 100x ocular lenses?
What microscope objective is best to study bacteria?
The most satisfactory way to study bacterial morphology 40x objective.
What micrscope objective is best to study bacteria?
100x with oil immersion
What objective focuses closest to slide?
The oil immersion lens @100x
What is the magnification of a high power objective?
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
How many platelets would be seen per 100x oil immersion field?
20 paltelets
What is the objective power if a 10X eyepiece produces a total magnification of 100X?
Using a 10X eyepiece, a student would need to use a 10X objective to have a final 100X magnification. 10 X 10 = 100X
Why is 100x microscope lens called oil immersion lens?
Because that lens (it does not HAVE to be a 100x lens - other lens magnifications are also available in oil immersion constructions) is made to be in contact with a drop of special oil which covers the specimen. The oil has the same index of refraction as the front lens glass and that way a different optical construction can be used.
