What objective focuses closest to the slides?
The oil immersion lens @100x
What is the magnification of objects observed through a 100X oil immersion objective with a 7.5X eyepiece?
750 X times
The total magnification achieved when using a 100x oil immersion lens with a 10x binocular eyepiece is?
1000X magnification
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
Maximum resolution can be achieved when using the oil immersion lens by implementing what procedures?
1. Focus very carefully with the 40x objective. 2. Rotate turret half way. 3. Apply a small drop of oil. 4. Rotate 100x objective into the immersion.
What objective focuses closest to the slides?
The oil immersion lens @100x
What mirror is used for oil immersion?
100x lens is used with oil immersion
Which objectives focuses closest to the slide?
oil immersion
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 maximum magnification of the dark-field microscope?
Most go up to 1000x as it is light field microscopy. The ocular lens (the one that you look into) is 10x, but there are different objectives to focus on the specimen that you rotate to chose. The lowest is usually 4x, then 10x, 40x, and then 100x. Multiply ocular lens (10x) X objective lens you are using (ex: 40x) = Total 400x Oil immersion drop is used ONLY on the 100x objective.
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 is the magnification of objects observed through a 100X oil immersion objective with a 7.5X eyepiece?
750 X times
The total magnification achieved when using a 100x oil immersion lens with a 10x binocular eyepiece is?
1000X magnification
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.
What is the function of the oil used with the oil immersion lens?
So that you do not scratch the lens because at 100x magnification it is very very close to the slide.
