The 'object lens' in a compound microscope is closest to the object being examined.
That is called the "objective lens." You can remember it because it is closest to the object you are looking at.
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.

On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
Arm = supports top part of microscope Base = the part the microscope stands on Lens turret= a rotating support for the objective lenses objective lens or lenses are those closest to the object being viewed. Their degree of magnification is usually marked on the side of the lens, eg. 100x magnifies the object 100 times. The longer the lens, the greater its magnifying power. Eyepiece (or ocular lens) = This is the lens closest to the eye and its magnifying power is generally marked on the side. To determine the total magnifying power of a compound microscope, multiply the power of the ocular lens with the power of the objective lens. For example, a 10x ocular with a 100x objective would give a total magnification of 1000. A microscope may also have a binocular eyepiece with a lens for each eye. Stage Clip= holds the glass slide which contains a specimen to be viewed. Stage- holds the specimen. Coarse adjustment knob- makes large adjustments to the focus of the lenses. Fine adustment knob- makes small adjustments to the focus of the lenses Below the stage is located either a mirror or an electric light which directs light through the specimen on the stage.
The objective lens
The main parts of a microscope include the eyepiece, objective lens, stage, light source, and focusing knobs. The eyepiece magnifies the image, the objective lens provides additional magnification, and the stage holds the specimen. The light source illuminates the specimen, while the focusing knobs adjust the focus of the image.

That is called the "objective lens." You can remember it because it is closest to the object you are looking at.
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
An objective lens gathers light passing through the specimen on the microscope and projects the image into the body of the microscope. Objective lens are closest to the specimen.
The objective lens is found on the nosepiece of a microscope that ranges from high to low power. It is the lens closest to the object being examined.
It's called an "OCULAR" according to a microscope supplier site.
Under the objective lens there is a stage to put the specimen ( the thing you want to look at ).

I think it's the microscope lens or the objective lens. Hope this helps!
