Abstract
A light focusing device for detachably coupling to a camera with a built-in flash. The device comprises a mount for detachably coupling to the camera; a housing coupled with the mount, the housing configured to enclose the built-in flash when the built-hi flash is an enabled position and comprising an alignment verification window; and a lens coupled with the housing such that light generated by the built-in flash is focused by the lens such that intensity of the light is increased farther away than what the built-in flash is able to do on its own. One or more spacers are included to adjust the height of the housing with respect to the flash for proper alignment.
