A practical optical workflow

Move from target requirement to a lens decision you can defend

Lensdatum keeps sensor geometry, production constraints, lens candidates, tolerance assumptions, field checks, and evidence in one local project.

Define the field

Enter the active sensor, resolution, target envelope, smallest feature, clearance, edge reserve, working distance, aperture, exposure, and motion.

Solve the window

Find focal limits that satisfy target fit and pixel sampling, then review standard focal choices and a balanced starting point.

Stress candidates

Rank supplier lenses by their worst focal, distance, and active-area tolerance corner, with distortion and minimum focus included.

Validate the field

Measure a known span, compare it with the predicted width, recover effective focal length, and retain each field check.

Margins before procurement

See where a nominal answer stops being enough

Focal sensitivity, diffraction, motion blur, depth of field, distortion reserve, minimum focus, and tolerance corners stay visible beside the requirement they affect.

Bounded by design

First-order planning, with the limits left visible

Lensdatum does not certify a lens or replace supplier data, optical simulation, measured commissioning, or qualified engineering review. Real systems can vary with principal-plane location, distortion, focus breathing, image circle, MTF, mount, wavelength, lighting, and production tolerance.

The included project is labeled as a synthetic demonstration. Replace its values with measured project data and applicable supplier information.
