What is the company's layout in the laser field? Will it be a major source of income that the company values ​​in the future?

Ruichuang Micronano: Hello! In terms of laser, we focus on laser sensing technology and product development, and are committed to building the R&D and manufacturing capabilities of serialized laser ranging and lidar products, mastering core technologies such as solid-state lasers, TOF ranging technology, high damage threshold laser coating, and 3D laser imaging. The laser ranging product line layout includes erbium glass lasers, erbium glass ranging modules, semiconductor ranging modules, and ranging machines. It has the characteristics of human eye safety, small size, light weight, low power consumption, high precision, and good reliability. The maximum range covers 1~20km. The products are widely used in drones, outdoor handheld observations, optoelectronic turntables and other fields, and batch delivery has begun. The development and iteration of serialized lidar products have been carried out, mainly for applications such as vehicle-mounted automatic assisted driving, unmanned vehicles and robots. Product types include MEMS galvanometers and rotating mirror scanning hybrid solid-states. The laser wavelengths include 905nm and 1550nm, which can meet the needs of 3D laser imaging applications at various distances within 500m. The company has formed a new pattern of focusing on infrared business and gradually making breakthroughs in multi-dimensional sensing fields such as microwaves and lasers, which has strongly supported the company's sustained and rapid development. As one of the company's main businesses in the sensing field, the laser business is expected to become an important source of income for the company in the future. Thank you for your attention!
