Many microscopes have a rotating disk under the stage. This diaphragm has different sized holes and is used to vary the intensity and size of the cone of light that is projected upward into the slide. There is no set rule regarding which setting to use for a particular power. Rather, the setting is a function of the transparency of the specimen, the degree of contrast you desire and the particular objective lens in use.
The iris adjustment on a microscope controls the amount of light passing through the specimen. By adjusting the iris, you can increase or decrease the brightness of the image, which can help improve clarity and contrast when viewing the specimen.
Coarse wheel adjustment on a microscope refers to the large knob used to move the stage up and down rapidly to bring the specimen into approximate focus. It is used to make rough adjustments to the focus before using the fine adjustment knob for precise focusing.
The iris diaphragm is named after the iris, the colored part of the eye, because of its similar appearance and function. Just like the iris controls the amount of light entering the eye, the iris diaphragm in a camera lens controls the amount of light entering the camera.
The function of an iris diaphragm on a microscope is to adjust the size of the aperture, controlling the amount of light entering the lens system. By changing the diameter of the iris diaphragm, you can adjust the depth of field and improve image contrast and clarity.
Limits the amount of light and changes the depth of focus.

The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
To determine if the bicycle rear wheel bearings are loose and need adjustment or replacement, check for any play or wobbling in the wheel when it is spun. If there is noticeable movement, the bearings may need adjustment or replacement.

There will need to be an alignment done on the vehicle to straighten the steering wheel properly. The adjustment to make it straight is called a "toe Adjustment". If it pulls while driving causing the steering wheel not to be straight it will need a Caster or Camber adjustment or all of these may need adjustmnet.
The function of a rack end is to connect the steering rack to the tie rod in a vehicle's steering system. It helps to transfer the motion from the steering wheel to the wheels, enabling the vehicle to turn left or right. Rack ends also allow for the adjustment of the wheel alignment for proper steering control.

The radial and circular muscles of the iris.
Could be worn ball joints, worn steering linkages, worn/out of adjustment steering box and or worn/out of adjustment wheel bearings.
It is used to cut soft tissue.
The iris controls the size of the pupil. Which in turn, controls the amount of light entering the eye.
