Technical Field

[0001] The utility model relates to the technical field of laser module focusing, in particular to a laser module focusing device. Background Art

[0002] The laser module focusing device is a device used to adjust the focus of the light beam. It is usually composed of a lens and a focusing mechanism. The lens is used to focus the laser beam, and the focusing mechanism is used to control the position of the lens. The main purpose of the focusing device is to make the focus of the laser beam reach the desired position to meet the requirements of different applications. The focusing device can change the position of the lens as needed, thereby changing the focal length and focal position of the laser beam. It usually uses an electric or manual mechanism to achieve focusing. The electric focusing device can be achieved by an electric drive or a stepper motor, and can accurately control the position of the focus. The manual focusing device requires a manual knob or button to control the focal length. The laser module focusing device is widely used in many fields. For example, in laser cutting and laser marking, the focusing device can be used to control the energy density and focal depth of the laser beam. In applications such as laser imaging and laser excitation fluorescence, the focusing device is used to adjust the size and clarity of the imaging or excitation area. However, in the use of traditional laser module focusing devices, traditional laser module focusing devices may make noise when focusing, especially when using the autofocus function, which may affect normal use when used in some environments that require relative quietness.
