1. Interactive 3D Microscope Controls
Rotate the 3D model with left-click drag. Scroll mouse wheel to zoom in/out. Observe the physical stage moving up/down when coarse/fine focus knobs turn, and watch the nosepiece turret rotate when changing objectives (4x, 10x, 15x).
2. Z-Stack Focal Depth Slicing
Biological tissue slides are 3D structures with real depth. Moving the Fine Focus Knob changes the optical focal slice height. Cells at shallow depth levels come into focus first, followed by deeper cellular layers!
3. Staining Chemistry Specificity
Methylene Blue (C16H18ClN3S): Cationic basic dye binding negatively charged nucleic acids in nuclear heterochromatin.
Iodine Solution (I2KI): Highlights cellulose plant cell walls and starch granules in rich mahogany amber hues.
