Institutionum opticarum partes quatuor conscriptae in usum tironum
Institutionum opticarum partes quatuor is an 1775 optics textbook by Karl Scherffer, printed in Vienna by Johann Thomas von Trattnern for students learning the subject. Its plates are dense geometric diagrams of rays, lenses, spheres and construction lines drawn in fine black engraved line on pale paper, offering a designer clean technical linework, labelled figure keys and a precise schematic vocabulary for diagram-based graphics.
