STOMmini · Field imaging kit

A microscope-grade imaging kit that fits in a field bag.

A smartphone, a clip-on lens, a calibration slide and a rugged case — everything you need to capture protocol-compliant stomatal images on-site. Always loaned, never sold, and validated across 27 species.

WHAT'S IN THE CASE?

1

Smartphone

Runs the guided capture app that enforces the acquisition protocol.

2

Clip-on lens

Microscope-grade optics (Apexel) that clip over the phone camera.

3

Calibration slide

Sets the exact scale so measurements are comparable across sites.

4

Rugged case

Field-ready protection so the whole kit travels safely.

PREPARE. CAPTURE. CHECK. UPLOAD.

STOMmini owns the physical acquisition layer — from the first PoC images to full-scale project capture.

01

PROJECT & PROTOCOL

Train operators for reliable acquisition.

MIAtecs trains every user to apply the acquisition protocol and capture the best possible images from the very first session.

Across species

Stomata imaged across eight crops.

Stomatal density, size and aperture govern how a plant trades water loss for carbon gain — the core of drought tolerance. Because every species regulates its stomata differently, MIAtecs builds a dedicated detection model per crop rather than a one-size-fits-all algorithm.

Wheat stomata imaged with STOMmini

Wheat

Stomatal density tied to water-use efficiency — a key selection trait in water-limited regions.

Maize stomata imaged with STOMmini

Maize

Rapid stomatal closure under water deficit — a direct indicator of summer drought tolerance.

Rice stomata imaged with STOMmini

Rice

A major factor in rainfed rice, where stomatal regulation drives yield outside submerged conditions.

Apricot stomata imaged with STOMmini

Apricot

Sensitivity to summer water stress directly linked to leaf stomatal conductance.

Tomato stomata imaged with STOMmini

Tomato

Stomatal dynamics provide a direct view of water-stress response and recovery under controlled conditions.

Rapeseed stomata imaged with STOMmini

Rapeseed

A targeted trait for variety selection against combined autumn and spring water stress.

Grapevine stomata imaged with STOMmini

Grapevine

Isohydric/anisohydric stomatal regulation — a selection criterion for rootstock and variety in warm climates.

Coffee stomata imaged with STOMmini

Coffee

Stomatal density and size linked to resilience against lengthening dry seasons.

…and much more species.

Not on the list yet? Here's how we add a species:
  1. Phase 1 — Proof of concept: we validate detection on a small sample of your species.
  2. Model build: a dedicated AI model is trained and validated for that species.
  3. Full project: we roll out high-throughput phenotyping across your trials.
