Abstract: A biological detection chip includes a base, multiple microstructures, a conducting layer, and a nano metal layer, wherein the base is provided with a surface; the multiple microstructures are arranged on the surface; and each of the microstructures protrudes out of the surface, and is provided with a first inclined plane and a second inclined plane inclining towards each other. The conducting layer covers the surface and the multiple microstructures, and the nano metal layer covers the conducting layer. The biological detection chip may increase the number of antibodies attached to the nano metal layer, so that the detection efficiency is improved.

Abstract: A zoom lens module includes a lens barrel, a piezoelectric actuator, and at least two lens modules. The piezoelectric actuator is disposed within the lens barrel. The piezoelectric actuator includes a piezoelectric ceramic component and a sliding member. At least one of the lens modules is attached to the sliding member. The other lens module is fixed in the lens barrel. The piezoelectric ceramic component drives the sliding member to move in a selected direction along an optical axis of the zoom lens module, so that the at least one lens module is moved relative to the other lens module, thus changing the focus of the zoom lens module (e.g., zoom or widen).

Abstract: An image pickup assembly with a filter lens includes a barrel, a first lens and a second lens. In this case, the barrel has a container and a diaphragm. The first lens is accommodated in the container. The second lens is also accommodated in the container. Wherein, at least one of the first lens and the second lens is a filter lens.

Abstract: A camera lens includes a barrel, a first lens, a second lens and an optical filter module. The barrel includes a first container and a diaphragm. The first lens is disposed in the first container next to the diaphragm. The second lens is disposed in the first container with a distance from the first lens. The optical filter module is disposed in the first container between the first and the second lenses.
