レンズ図鑑

Lenses from published patents, drawn and shelved

An atlas of lens data from published patents, drawn out as figures. Specifications, layout diagrams and aberration plots, compiled mechanically in a fixed format. No verdicts — just a shelf for looking at what is inside a lens.

Ground rules for this atlas

  • What is shown here is embodiment data written in published patents, which anyone can read.
  • All figures and values are calculated values, recomputed in a personal environment. They are not product measurements.
  • The correspondence between a patent and any product has not been verified (no guesses are made).
  • No verdicts on what is better or worse. Entries are compiled mechanically in a fixed format.

Being prepared

Lens data from published patents will be added here one sheet at a time, in a fixed format: specifications, layout diagram and aberration plots.
