Abstract
The invention discloses an electric lens diaphragm unit comprising a lens tube and a motor. The lens tube is connected with a motor case. The motor is arranged within the motor case. The motor is connected with the lens tube through a focusing nut. The focusing nut is in fit connection with a focusing board. A focusing positioning screw is arranged between the focusing board and the focusing nut. In this way, the electric lens diaphragm unit with a sapphire high-temperature-resistant lens is free of a high-temperature-resistant coating on the surface, high in high temperature resistance and high in stability; with the motor, the electric lens diaphragm unit allows aperture size to be remotely and electrically controlled.
Description
