What is the function of draw tube in microscope?

What is the function of draw tube in microscope?

The drawtube (if present) carries the ocular, it can be adjusted to control tube length and so effect corrections for the objective lens. The drawtube may also be convenient in calibrating an eyepiece-micrometre by allowing a minor magnification change to simplify the conversion factor.

Where is the body tube of a microscope?

Above the stage and attached to the arm of the microscope is the body tube. This structure houses the lens system that magnifies the specimen. The upper end of the tube contains the ocular or eyepiece lens. The lower portion consists of a movable nosepiece containing the objective lenses.

What is the function of tube lens in microscope?

Modern microscopes combine the objective with a second lens hidden in the microscope body, the tube lens. This tube lens allows for advanced light manipulation techniques, such as infinity-corrected imaging, as seen in Fig. 5. The sample or object is placed at the focal plane in front of the objective.
