X-y mechanical stage knobs

Definition

X-Y mechanical stage knobs are controls on a microscope that allow precise movement of the slide in horizontal (X-axis) and vertical (Y-axis) directions. They enable the user to navigate and position the specimen accurately under the objective lens.

5 Must Know Facts For Your Next Test

1. They provide fine control for moving slides, ensuring accurate positioning of specimens.
2. X-Y mechanical stage knobs help in scanning large areas of a specimen systematically.
3. The X knob moves the slide left and right, while the Y knob moves it forward and backward.
4. These knobs are essential for high magnification observations where precise adjustments are necessary.
5. Proper use of X-Y knobs can prevent damage to slides and objective lenses by avoiding sudden movements.
