EXPLORE THE SLIDE

Start with a little light.

Switch on, move across the slide and choose a shape that catches your eye.

TAKE YOUR TIME

Follow your curiosity.

  1. Light on, 4×. Move across the slide. There is more beyond the first view. Any shell can be a discovery.
  2. Choose a shape. Tap inside a shell to centre it. Or drag it towards the cross using the image or arrow buttons.
  3. Look closer. Try 10×, then 40×. Each objective keeps the same centre and focus, but shows a smaller area.
  4. Explore focus. Use coarse steps to get closer, then fine steps to see the pore pattern or fine lines sharpen.

If the shape disappears, return to 4×. “Return to the starting area” restores the first field without changing focus.

Guidance is always welcome. Nothing is scored.

Nature builds in glass.

A round valve

Preparing the 3D illustration…

Explore one generic valve, one half of a diatom's two-valve shell. This illustration represents the discovered shape; it does not identify a species or reproduce your exact specimen. Each illustration is sized to fit this view, so their displayed sizes cannot be compared.

Diatoms are microscopic algae. Their intricate cell walls contain silica — the main ingredient of glass. Those walls can remain after the living cell is gone.

This slide models prepared shells, so nothing swims away. The round valve has rows of tiny openings; the long valves show a different form. The patterns here are illustrative and do not identify a species.

82 µm

The round shell in this model is just 0.082 millimetres across.

What changed when you looked closer?

The objective narrowed your field of view. Its higher numerical aperture also let you resolve finer detail. Turning focus aligned the shell with the sharpest plane. Enlarging a blur alone would not reveal more structure.

BEHIND THE DISCOVERY

A model with honest limits.

The microscope is interactive 3D. The brightfield view is a generated teaching image of stationary, prepared diatom shells, not a microscope photograph. Colours and shell geometry are illustrative.

A fixed camera field is scaled by the 4×, 10× and 40× objectives. Their numerical apertures are 0.10, 0.25 and 0.65. Resolution and defocus affect the whole image continuously using an approximate Gaussian blur at 550 nm; this is not a full wave-optical calculation.

Image brightness is kept comparable between objectives. The camera view is displayed upright for navigation. Fine stage motion is exaggerated on the 3D stand. Objective changes retain the same field centre and focal plane. Real instruments may need additional alignment and careful handling.

The optional 3D illustration shows a generic single valve, one half of a diatom's two-valve shell. Thickness and pores are simplified. It is not a reconstruction, a measurement, or a species identification. Its enlarged shape is separate from the prepared-slide image and does not change the optical model or kept comparisons.

MODELLED · PREPARED SLIDE

The optical information is unchanged.

What is in this view?

The same controls work with keyboard arrows, touch or a mouse. The focus control accepts arrow keys; the camera view accepts arrow keys to pan.

Each set compares the same shell at the position and focus you found. Only the objective changes. These views stay unchanged while you explore.

At 10× you may see a hint of rows. At 40×, the higher numerical aperture and careful focus separate the finer structure.
