From loading to a saved TEM image
About 15–20 minutes · synthetic cross-grating specimen. Load and check vacuum → navigate → illuminate → magnify → focus and correct astigmatism → acquire, review and download → blank the beam.
The explanation and video use other example specimens. This course changes to a synthetic cross-grating for phase-contrast practice. Its −66 nm focus target belongs to this teaching model, not every TEM image.
Independent brief: load the grid, find X 0.5 µm / Y 0 at 1,000×, centre illumination, use brightness 0.32 and spot 3, increase to 20,000×, focus at −66 nm, correct both stigmators to zero, then acquire at 0.5 s, review, download and blank. These targets belong to this teaching model.

What changes when you increase magnification around a centred feature?
Load a synthetic grating → pump and insert → focus → acquire an image. About 4–5 minutes.
When enabled, the control panel scrolls to each control and shows the trainer’s click or value change. The pointer stays inside this simulator and does not move your laptop’s mouse.
This lets the trainer run the displayed sequence on the simulated microscope. Current settings will change. Lesson completion is not awarded. Stop demo returns control to you.
Connect voice training for AI narration and questions. The visible demonstration also runs without a voice connection.

Adjust the controls on the right and watch the live detector. Only the controls scroll; the image stays in view. Use Maximise workspace for a larger image.
