GENERAL HISTOLOGY

Detailed explanation-1: -Objective Lens or Numerical Aperture This part of a compound microscope is the lens closest to the specimen. Ocular Lens In a compound light microscope, this is the lens closest to the viewer.

Detailed explanation-2: -Answer and Explanation: The 100x objective focuses closest to the slide when it is in focus. The distance between the specimen and the objective lens is called the working distance.

Detailed explanation-3: -There are two sets of lenses in both the compound microscope and the dissecting microscope (also called the stereo microscope). Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through.

Detailed explanation-4: -The objective lens is closer to the sample or specimen under observation, while the ocular lens is farther to the sample and closer to the observer. The objective lens function by magnifying the specimen while the ocular lens magnifies the magnified image of the specimen for better resolution.

Detailed explanation-5: -Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above).
