This work is an excellent summary of seventeenth-century optical instruments and their construction, and includes several devices, such as the binocular microscope and telescope, invented by Cherubin.Chérubin d'Orléans was the inventor of theater binoculars and, in this practical work on optics, he systematically describes lens grinding, telescope manufacture, and illustrates every aspect of a lens maker's workshop in detailed engraved plates. According to Albermt, La dioptrique oculaire is "the most comprehensive treatise on lens manufacture in the seventeenth century." Chérubin d'Orléans includes detailed accounts of the effects different lenses have on the eye and observations of the stars and moon made through telescopes of his own invention. The Antiporta is engraved Gerard Edelinck (1640-1707) on the drawing by Jean le Pautre (1618-1682).
