Abstract: An optical film includes at least one light-absorbing film layer and at least one anti-reflection film layer formed on the at least one light-absorbing film layer. A material of the at least one light-absorbing film layer is a mixed powder of chromium metal and SixOy. The x and the y are respectively greater than 0 and positive integers. The disclosure further relates to an optical lens and a lens module. The optical film can reduce the effect of stray light on the imaging quality.

Abstract: A sputtering apparatus includes a support assembly and posts. The support assembly includes an upper base, a lower base, seat members, and connection posts interconnected between the upper base and the lower base. The upper base defines cutouts. The seat members are rotatably mounted on the lower base and aligned with the cutouts. Each seat member includes a hollow receiving post, a support post moveably received in the receiving post, a lever bar pivotably connected to the receiving post, and a drive post, the drive post and the support post are coupled to opposite ends of the lever bar. Each seat member is rotatable about a longitudinal axis of the receiving post. The posts fix workpieces in place. Each post includes a rod body portion having a first end and an opposite second end, an engagement portion at the first end, and a protrusion extending from the second end.
