Slida

A slide is decided before it is cut. Slida is the bench where you compose a mount on purpose and read what that recipe will actually look like down the tube. COMPOSE THE MOUNT Specimen, fixative, section thickness in micrometres, an ordered stain schedule with a time on every step, clearing agent and mounting medium, coverglass number, and the objective you will view it through. READ THE FIGURES The resolution limit, the depth of field, the penalty your coverglass thickness costs that objective, and a contrast index - all recomputing as you change the section thickness or the schedule, with the predicted field drawn beside them. THE ARTEFACT RANKING A ranked list of the faults this particular mount is likely to produce, each naming the step that corrects it. MEASURE A FINISHED SLIDE Photograph the field afocally through the eyepiece, tap two graduations of a stage micrometer and enter their spacing. Micrometres per pixel are fixed from that, so the caliper measures real features in micrometres - and the result is set against the figure the bench predicted, inside a tolerance band. THE ARTEFACT CLINIC Nine described faults: match what you are seeing, read the conditions that produce it, then apply the correction. The named field of the recipe is altered and the app states exactly what it changed. THE TRAY Every computed mount kept as a labelled slide card, filtered by stage, objective or open risk, sorted by date or risk score, under your own bench name. ON THE DEVICE Nothing is live and nothing leaves the device: Slida works before the slide exists and after it is finished.
