The condenser knob on the microscope is one of the most important parts of the microscope and is located under the eyepiece. It is responsible for delivering electricity to the power source, so the microscope can run. It has a series of wires, and the wire that connects to the microscope’s power source is the wick. The wick will be connected to the main light source and in some cases, a magnifier lens as well, such as when you are taking pictures using a microscope camera.
What happens with the condenser knob is that the wick will get caught in the ring-shaped slot on the side of the condenser. This ring will hold the coil of wire that runs through the condenser and will have the condenser coil sitting in the middle. This part of the condenser is the power source. The ring on the side of the condenser keeps the wire free from the slot, allowing it to be twisted around and to turn on the power supply for the microscope. When the condenser ring has been twisted around, it will turn the wick into the proper place and this will make the coil spin around and start running.
If you were to look inside a microscope, you would notice that the condenser knob is usually found on the right hand side of the microscope, but it may be on either side depending on which type of microscope you have. It may not even be found if you are holding the microscope up to your eye, because it is placed in the eyepiece. There are some microscopes that do not have the condenser knob, so you will have to find it if you want to use a condenser on your microscope. It is a very simple and convenient part of the microscope.
