In this paper we continue the investigation of further properties of secantoptics introduced and considered by Skrzypiec (Beiträge Algebra Geom. 49(1):205–215, 2008) and by Mozgawa and Skrzypiec (Bull. Belg. Math. Soc. Simon Stevin 16(3):435–445, 2009). We describe properties of secantoptics of ovals of constant width, prove a theorem on tangents to secantoptic and give the converse of the sine theorem for secantoptics.
