What is the depth of field on a microscope?
Depth of field is the depth of the specimen clearly in focus and is greater at lower magnifications.
Why should you not use the fine focus to bring an object into view on a microscope?
Simply because the fine focus moves too quick to get the object focused. Chances are you will miss the focus point.
What is fine adjustment of the microscope?
You use the fine adjustment to focus in HIGH power with a compound microscpe.
Why do you have to be carefull when you are focusing the high power lens?
On a microscope, you have to make sure to use the fine focus instead of the coarse focus. If you are not careful and you do use the coarse focus, it will move the barrel down and the lens may crush your slide/slide cover. Which is very, very bad.
When do you use fine focus and the coarse focus knobs?
The fine focus knob is used to bring an object into fine focus, while the course focus knob is used to bring an object into approximate focus. The course focus knob should only be used on the low-power and scanning objectives of the light microscope. Using it on the high power microscope is okay, but you should be very careful. It is no recommended to use the course adjustment knob on the oil-emersion objective as it is so close to the stage and could lead to a potential break in the slide. Fine focus adjustment knob is useful to bring out the fine details in the specimen on your slide. Can be used on any of the objectives, but most receptive on the high-power and oil-emersion objectives.
