Optical sensing device and optical lens

Abstract

An optical sensing device includes a circuit board and an optical lens. The optical lens includes a substrate, electrical contacts, a support, a first lens barrel, a second lens barrel, an optical module, and a processing module. The substrate includes a base and a protrusion disposed on the base. The electrical contacts are disposed on the substrate. The support is disposed on the side of the base opposite to the protrusion. The support has a first opening and a second opening. The first lens barrel is connected to the first opening, and the second lens barrel is connected to the second opening. The optical module is disposed on the side of the base opposite to the protrusion and is used to generate a light-sensing signal. The processing module is disposed on the side of the base opposite to the optical module and is electrically connected to the optical module to drive the optical module to transmit the light-sensing signal via the electrical contacts. The circuit board is electrically connected to an electrical connection portion to receive the light-sensing signal through the electrical contacts.
