Kurzer Bericht von den Resultaten neuerer Versuche über die Gesetze des Lichtes, und die Theorie derselben.
(Leipzig, Barth), 1823.. (20 x 12 cm). SS. (337)-378. Broschur der Zeit. (Sonderdruck aus: Annalen der Physik).. Seltene erste Ausgabe. "In the paper prepared in 1823, Fraunhofer revealed his continued investigation of diffraction gratings... He continued his study of the effect of oblique rays, developed formulations based on a wave conception, and calculated a revised set of wavelengths for the major spectral lines. Thus, his earlier observations of the dark lines in the solar spectrum enabled him to make the highly precise measurements of dispersion: then his use of the wave theory of light allowed him to derive, with suitable simplifications, the general formulation of the grating equation still in use today" (DSB). - Leicht gebräunt und bestoßen, sonst gut erhalten. - DSB 5, 142
