Quartz lens is an important optical element, with high light transmission, thermal stability and mechanical strength, so it has a wide range of applications in the field of laser technology. The main applications of quartz lenses in laser technology are described below.

First, the quartz lens plays the role of optical reflection and transmission in the laser system. The laser system is composed of a laser, an optical isolator, an optical stabilizer, etc., in which the optical isolator and the laser generally use a high reflector and a half lens to achieve optical reflection and transmission. Because of its high transmittance, high reflectivity and high thermal stability, quartz lenses have become the primary materials for the manufacture of these optical components.

Second, quartz lenses play a key role in laser interferometers. Laser interferometer is a device for interference experiment through coherent light wave generated by laser, which is often used in length measurement, surface topography detection and other fields. As a reflection lens in the interferometer, the quartz lens can accurately reflect and refract the laser beam to ensure the stability and accuracy of the interferometer.

Quartz lenses have important applications in laser cutting and laser welding. Laser cutting is a technology that uses the high energy density of the laser beam to cut the material, and laser welding is a technology that uses the high energy density of the laser beam to weld the material. Quartz lenses are often used as laser output Windows or focus lenses, which can withstand the irradiation of high energy laser beams to ensure the stable transmission and focusing of laser beams.

Quartz lenses are also widely used in laser sensors. Laser sensor is a kind of sensor which can measure the property or shape of the measured object through the interaction between the laser beam and the measured object. The quartz lens can reflect and transmit the laser beam with high quality, which is used to control and adjust the optical path of the laser beam to ensure the reliability and accuracy of the laser sensor output.

Quartz lenses are also widely used in the field of laser marking and laser etching. Laser marking is a technology that uses the heat energy of the laser beam to permanently mark the material, and laser etching is to use the high energy density of the laser beam to etch off a layer of material on the surface of the material to achieve the purpose of marking or engraving. Because of its excellent thermal stability and high light transmission, quartz lenses can withstand the high energy density of the laser beam to ensure the focusing and accurate control of the laser beam.

Quartz lenses are also widely used in radar and liDAR systems. The radar system is used to detect the position, speed, orientation and other information of the target, among which LiDAR is a sensor that measures the distance and shape of the target through the laser beam.

Quartz lenses are used as optical reflective lenses and transmission lenses in radar and Lidar, which can ensure the quality and transmission effect of laser beam, improve the performance and measurement accuracy of radar and Lidar.

In summary, quartz lenses have important applications in laser technology. Whether it is in the optical reflection and transmission of laser systems, or in the fields of laser interferometer, laser cutting and welding, laser sensors, laser marking and lidar, quartz lenses play an important role, providing key support and guarantee for the development and application of laser technology.
