nosepiece
This is called the nosepiece.
Some microscopes have zoom, so you just turn a knob. With others, you rotate in a different lens.
I have always had the longest objective in position (pointing down), then lowered the lens to what I thought would be close to a good focus. This way, you can rotate the turret to the shorter lenses, and be assured that the lens body will not strike the stage or slide.
Rotating the body tube allows you access to other parts of the microscope that may need cleaning/repairing.

Rotate the revolving nosepiece to the appropriate objective (10x, 50x, etc.), then use the adjustment knob to sharpen the image and get rid of any blur.

is where the arm of the microscope connects to the base of the microscope

because you didn't refocus the microscope.
An inclination joint of a microscope is where the arm of the microscope connects to the base of the microscope. Many microscopes have a pin to hold these to objects together. If the microscope is equipped with the pin you can place one hand on the base and with the other hand you can grab the arm and rotate it back and forth. The inclination joint allows the microscope to tilt back for more comfortable viewing. Please note, there is no way to contain liquid specimens if you tilt your microscope back the liquid will spill to the ground or all over.midfielder_francis@yahoo.com
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.

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.
Always carry a microscope with two hands. Place one hand under the base of the microscope and hold the arm with the other hand. Do not allow the microscope to drop or bump into anything while carrying it. This could damage the microscope or cause small pieces to break off that could cause a tripping hazard. Touching the microscope lens can smudge or damage it. Always use lens paper or a soft cloth with a small amount of isopropyl alcohol to clean a dirty microscope lens. Remove slides and cover slips from the stage before storing the microscope, and rotate the nose piece so that the smallest power objective is facing the stage. Place a dust cover over the microscope when storing it to prevent dust and dirt from damaging the machine. Read more about Microscope Saftey Procedures in the related link.
