Abstract: An optical detecting device includes a light source, an optical detecting component, a package structure and a light tight component. The light source outputs a sampling signal to project onto an external object. The optical detecting component is disposed by the light source and has an interval relative to the light source. The optical detecting component receives the sampling signal reflected from the external object. The package structure covers the optical detecting component and the light source, and includes an illuminating surface unit and an incident surface unit respectively corresponding to the light source and the optical detecting component, and further includes an isolation component disposed between the illuminating surface unit and the emerging surface unit. The light tight component is disposed on the isolation component to obstruct transmission path of the sampling signal from the illuminating surface unit to the incident surface without reflection by the external object.

Abstract: An optical lens is configured in front of an image-capturing lens of an image-capturing device. A light-emitting unit of the image-capturing device emits a light beam. The optical lens includes a pair of peripheral compensation portions and a central diverging portion. Each peripheral compensation portion has a first convex surface and a first concave surface arranged opposite to the first convex surface. The central diverging portion is arranged between the peripheral compensation portions, and has a second concave surface and an oppositely arranged light incident surface. The second concave surface is arranged between the first convex surfaces. The light incident surface is arranged between the first concave surfaces. The optical axis of the light beam sequentially aligns with the light incident surface and the second concave surface. The light rays of the light beam pass through the first concave surface and the first convex surface in sequence.
