Objective lenses
Objective Lens
The nosepiece of a microscope holds multiple objective lenses, each with different magnification levels that range from high to low power. Rotating the nosepiece allows you to switch between these objective lenses to adjust the magnification of your specimen.
The revolving nosepiece or turret rotates to change from the low power objective lens to the high power objective lens on a microscope. This component allows for easy switching between different objective lenses without the need to manually remove and insert them.
The revolving nosepiece of a microscope holds multiple objective lenses that can be rotated into position to magnify the specimen being viewed. This allows for quick and easy changing of magnification levels without having to manually switch lenses.
High powered microscopes have a light source and can magnify up to 1000 times.

Turning the nosepiece to the Low Power Objective (LPO) before putting the microscope away is important for several reasons. It helps protect the more delicate high-power objectives from damage by ensuring they are not in contact with the slide. Additionally, starting with the LPO makes it easier for the next user to locate and focus on the specimen quickly. This practice also maintains the longevity of the microscope and ensures it remains in optimal working condition.
The 15 parts of the microscope are the ocular, tube,arm,revolving nosepiece, clips,low power objector,medium power objector,high power objector, stage, coarse adjustment knob, diaphragm, light source, incline adjustment, base.
yes it has reverse and both high and low range gears . i can get it to run in both forward and reverse but only in low range . when i shift IT into high range it is still running in low range .
If you ask some elder staff of your class (if you are a student) they'll probably suggest you to move the body of the microscope a little higher. But according to my experience you can just turn it from low power to higher power with ease until you hear a click sound (so that the objective is locked).
The price range could be from $80-$400 from what I have read online to find out for you. I am not sure why the range is so high, probably advanced models with more features.
An electric range should use a heavy-duty power cord that is rated for high voltage and amperage, typically a 4-prong cord with a 240-volt rating.
