Why must the distance from slide to objective lens increase rather than decrease when coarse focusing with the scannin and low power objectives?

According to my neurons that the distance from slide to objective lens should be increase rather than decrease when coarse focusing with the scanner and LPO to obtain a clearer and more focus structure of a certain specimen.. U must ensure that the coarse adjustment knob is at it's extent and then turn on the fine adjustment knob clockwise for the easier visibility of the specimen =)) - VALERIC ACID ...sPCUTE ..=)

When you get close to the chair, you look closer to make sure no one else is sitting in it or to see nothing is resting on the cushion. You use distance vision to find the chair. Then you examine it closely when you are close. Finally you check it to make it will support your weight. Then you sit down. Then you sit down. You start with the lens with the lowest magnification to locate the specimen. You move the specimen into the center of view. etc.


Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?

It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.


Why should you use the scanning objective to find objects first?

Try it any other way and you'll see. The scanning objective has the largest field of view, the greatest depth of field, and the greatest working distance. It is the most forgiving objective. It is the easiest to find the specimen and focus on it.
