Which objective would be better to use when using a scanning slide?

Might add extra, but i really hope this helps!
scanning objective - for locating the specimen on the slide (= low power objective)
high power objective - magnifies the specimen to provide a detailed image
coarse adjustment - used to focus the image when using low power
diaphragm - used to adjust the amount of light passing through the specimen
revolving nosepiece - holds the three objective lenses - it can be rotated to change the objective in use
arm - holds the stage and the lens system - can be used to tilt the microscope (but not advised)
substaGe lamp - provides a uniform illumination (more reliable than daylight !!)

Wiki User
∙ 15y agoa high power objective would be better, because it has a high magnification power.
Wiki User
∙ 12y agoIt is usually best to use low-power to initially locate the specimen - then go to higher-power (if needed).

What must NEVER be used when using the medium or high power objectives?
The coarse adjustment because it moves the objective much farther than the fine adjustment knob, and you could hit the slide with the objective and damage the lens and/or the slide.
When using the oil immersion lens you should raise the objective lenses for easy application of an oil droplet to the slide is this true or false?
False
Initial focusing of any slide is done under the?
When using a microscope, the initial focusing of any slide is done under either the 4x or 10x objective. Once you have your subject in focus, you may make further adjustments.
Why is it important to only use the fine adjustment knob when using the highest power objective lens?
When using high power, the lens is very close to the sample - and so you risk damaging the slide and/or lens if they touch - therefore you only want to move the platform a little bit at a time. It is very similar with an oil immersion - you don't want to damage the lens by allowing the sample to touch it.
When using the high power objective which focus knob do you use?
The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.
What are some of the best slide scanning services available?
While it is possible to purchase a slide scanner and do it yourself, some may prefer the convenience of using a slide scanning service. Some of the better ones include Scan Cafe, Go Photo, Dig My Pics, Scan Digital and Scan My Photos.

What are the change involved when view the prepared slide under microscope using different objective lens?
it has to do with the resolution of the image of the slide obtained...the larger the objective lens value is the greater the resolution it will provide, greater the resolution higher the details.
Why do you use on or slide to be examined with the oil immersion objective?
If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
A student is observing a slide of blood cells by using the low-power objective of a light microscope The cells are too small to examineso the student switches to the high-power objective The cells?
magnification.
When using the oil immersion lens you should raise the objective lenses for easy application of an oil droplet to the slide is this true or false?
False
Why should you always move the objective lens away from the slide when you're focusing a microscope?
If you move closer while looking thru the lens, there is a danger of cracking the slide, especially using coarse adjustment.
What is a sentence using scanning?
I can give you several sentences.A scanning electron microscope can see an atom.He is scanning the prices with a laser.We are scanning the room for our friends.

How does the procedure for using the microscope differ under high power as opposed to low power?
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
