Planned laboratories

FUTURE LABORATORIES / PLANNED

More ways to explore.

We plan to expand MVLscope with labs for chemical mapping, internal 3D structure and atomic-scale surface imaging.

RAMAN MICROSCOPYNext planned lab

What is it made of?

Explore how Raman spectra identify materials and reveal where different chemical components occur across a specimen.

X-RAY MICRO-CTPlanned

What is hidden inside?

Learn how X-ray projections combine into a 3D volume to reveal internal structures, pores and defects without cutting the specimen open.

STMLonger-term plan

What does an atomic surface reveal?

Explore scanning tunnelling microscopy: how tunnelling current reveals atomic-scale detail and surface electronic structure on conducting and semiconducting materials.

These laboratories are planned and are not yet available. No release dates have been announced.

JANA / SCALE NOTES

A cellular perspective.

A cell contains a world of structures. Fluorescence helps distinguish selected features by the light they emit.

Explore light & fluorescence ↗

These are comparative illustrations, not a continuous microscope zoom or measurements from a specimen.

02 / Make a discovery

A little focus.
A different world.

Move through a fluorescent specimen. Separate its channels. Notice what appears—and what disappears.

JANA asks
When a feature disappears, has it gone—or are you looking at a different depth?

Each lesson gives you something to try.

START HERE / INTRODUCTORY EXPERIENCE

What Is Microscopy—and Why Use It?

Meet a world smaller than a strand of hair. Rotate 3D models, turn light into an image, and discover which microscope answers your question. JANA guides you from the very beginning.

Make your first discovery

No prior knowledge · Four interactive chapters · Printable discovery record

See the teaching example

SCALE → SIGNAL → DISCOVERY

Look closer.
Understand why.

Close a shutter and the detector goes dark. Bring a specimen into focus. Compare light, electrons and a scanning tip. Every interaction explains a principle.

EXPLORE / ONE SPECIMEN, DIFFERENT MICROSCOPES

One tiny shell. Four different discoveries.

Follow the same region of a diatom’s silica shell through light, scanning electron, atomic force and transmission electron microscopy. Watch light, electrons and a scanning tip reveal different evidence, then prepare a thin section to look through its wall.

Explore the diatom

Linked 3D and image views · Named signal paths · No account required

PATTERN / SURFACE / HEIGHT / SECTION

Same region.
A different question.

Move the SEM detector. Change the AFM tip. Discover why a brighter pixel is not a height measurement—and why specimen preparation matters.

LESSON 01

Magnification versus Resolution

Follow the light in 3D. Enlarge two fluorescent points, open the objective aperture, and discover what actually reveals detail.

Start lesson 01

8–10 minutes · Guided experiments · Assessment · Downloadable record

See the teaching example

SAME 300 nm PAIR / 520 nm EMISSION

NA means numerical aperture: a measure of the objective’s light-gathering angle and medium.

NA 0.40793 nmNA 1.20264 nm

A smaller Rayleigh reference distance means closer features can meet the criterion. Display zoom alone leaves it unchanged.

LESSON 02

Focus and Depth of Field

Move through a 3D fluorescent specimen. Find a sharp plane, trade depth for detail, and collect the layers a single image misses.

Start lesson 02

10–15 minutes · Linked 3D and detector views · Z-stacks · Assessment

See the teaching example

SAME SPECIMEN / AIR / 520 nm

NA 0.258.32 µmNA 0.800.81 µm

A wider numerical aperture makes the diffraction depth reference thinner. Explore which layers stay near focus, and which contribute blurred light.

LESSON 03

Calibration, Scale Bars & Measurement

Turn image pixels into specimen dimensions. Calibrate a 3D micrometer slide, measure a fibre, and correct the error caused by an objective change.

Start lesson 03

12–15 minutes · Draggable endpoints · Scale bars · Measurement record

See the teaching example

ONE 30 µm FIBRE / TWO CALIBRATIONS

Wrong scale60 µmMatched scale30 µm

The specimen did not grow. Discover why calibration must match the objective and camera setup before reporting a measurement.

LESSON 04

Illumination & Contrast

Follow excitation and emission in 3D. Compare exposure and spectral selection, reveal camera clipping, and adjust the settings to avoid clipping.

Start lesson 04

12–15 minutes · Photon statistics · Spectral contrast · Printable record

See the teaching example

SAME FOCUSED SPECIMEN / DIFFERENT COLLECTION

Broad0.39Selective0.64

Relative contrast S/(S+B) at 30% excitation and 300 ms in this teaching model. More exposure alone leaves the ratio unchanged.

LESSON 05 / NEW

Sampling & Digital Images

Discover when more pixels help. Follow the image onto a named 3D detector, expose aliasing, compare binning and test what digital enlargement can really reveal.

Start lesson 05

12–15 minutes · Sampling & binning · 3D light path · Printable record

See the teaching example

SAME 40× OBJECTIVE / 6.5 µm CAMERA PIXELS

4 × 4 binning0.650 µm/pxNative pixels0.1625 µm/px

At NA 0.75 and 520 nm, the ideal widefield sampling target is at most 0.1733 µm per specimen pixel. Screen enlargement leaves sampling unchanged.
