Laser module group with controllable power

Abstract

The invention relates to a laser module group, particularly to a laser module with a controllable power. On the basis of the technical scheme, the laser module group is composed of an LD, an LD driver panel, a sensor, a bearing seat, an optical cement crystal, a semi-transparent and semi-transparent glass sheet, and a bracket. A light-transmitting hole is formed in the bottom of the bearing seat; and the LD is installed inside the bearing seat. The sensor is welded to the LED driver panel that is installed below the bearing seat; and the sensor corresponds to the light-transmitting hole. The optical cement crystal is installed on the LED; a notch corresponding to the light-transmitting hole is formed in the optical cement crystal; the bracket is installed on the optical cement crystal; and the semi-transparent and semi-transparent glass sheet is installed on the bracket. A certain angle is formed between the semi-transparent and semi-transparent glass sheet and a laser beam emitted by the LD, so that the laser beam reflected by the semi-transparent and semi-transparent glass sheet is emitted on the sensor through the notch and the light-transmitting hole. The laser module group has advantages of simple and compact structure, small size, and simple production process; and the batch production efficiency is effectively improved.

Description
