A method for assembling a lens module with an image sensor, includes providing a holder having first and second receiving spaces, disposing the image sensor in the second receiving space, locating lens barrel at a first position in the first receiving space, casting a light beam on the lens module to allow the lens module to converge the light beam into a light spot on the image sensor, determining if the light spot is at its smallest to determine if a distance between the lens module at the first position and the image sensor is equal to a focal length of the lens module, moving the lens module to a second position in the first receiving space to achieve a predetermined distance from the first position, and positioning the lens module at the second position.

An apparatus (20) for making nanopowder includes a reaction chamber (22), a first sprayer (25, 27), a second sprayer (26, 28) and a centrifuge (24). The reaction chamber includes a top portion (224); a bottom portion (227) opposite to the top portion; a peripheral sidewall (220, 223) interconnecting the top portion and the bottom portion; an inlet (222) formed in the top portion configured for introducing a solvent; and an outlet (229) formed in the bottom portion. The first sprayer is formed on the peripheral sidewall of the reaction chamber configured for spraying a first reactant into the reaction chamber. The second sprayer is formed in at least one of the top and bottom portions of the reaction chamber configured for spraying a second reactant into the reaction chamber. The centrifuge is connected with the outlet of the reaction chamber.

A solar cell assembly includes a first solar cell panel, a second solar cell panel, and at least one first light diverging lens. The first solar cell panel has at least one first through hole defined therein. The at least one first light diverging lens is embedded in the at least one first through hole of the first solar cell panel. The at least one first light diverging lens is configured for diverging sunlight incident thereupon and forming a first diverged light output. The second solar cell panel is spaced apart from the first solar cell panel and facing towards the at least one first light diverging lens. The second solar cell panel is configured for receiving and converting the first diverged light output into electric power.

A device for measuring adhesion strength between a first optical element and a second optical element includes a force gauge, a first magnet, and a second magnet. The second magnet is fixed to the force gauge. The first magnet and the second magnet are configured for magnetically attaching to opposite sides of the first optical element. An attractive force between the first magnet and the second magnet is greater than the adhesion strength between the first optical element and the second optical element.
