Laser lenses, as an important optical component, have a wide range of applications in multiple fields. The following is a detailed summary of the application of laser lenses:

1. Laser cutting:

   1. Principle: Using the high energy density after laser focusing, the material to be cut is heated to instantly melt or vaporize.

   2. Function of laser lens: During laser cutting, the laser lens plays a focusing role, focusing the laser beam on the cutting point to increase energy density and achieve efficient cutting.

2. Laser welding:

   1. Principle: Using a laser lens to focus the laser beam onto the welding joint, the joint material is instantly melted and solidified under high energy density, achieving welding.

   2. Characteristics: Fast welding speed, precise weld seam, widely used in the automotive industry, electronics industry and other fields.

3. Laser marking:

   1. Principle: Use a laser lens to focus the laser beam onto the surface of the marked object, and leave permanent marks on the surface through the thermal effect of the laser beam.

   2. Characteristics: Non contact, high-precision, high-efficiency, widely used in industries such as electronic products and medical equipment.

4. Laser excitation:

   1. Application scenarios: In some scientific experiments and optical instruments, laser lenses are commonly used to adjust the propagation direction and focus of laser beams to meet experimental requirements.

5. PCB mass production:

   1. New laser lenses: such as Silverline F-theta lenses, designed specifically for high-power and short pulse laser applications, with high precision and no reverse reflection, can be used for PCB board splitting, copper and brass metal material processing.

   2. Performance parameters: focal length of 163mm, minimum spot size of 13 μ m, capable of processing workpieces in a maximum scanning field of 65x65mm.

6. LED lighting:

   1. LED laser lens: used to focus the light emitted by LED, making the light more concentrated and improving the utilization rate of light.

   2. Structure: Typically composed of a series of lenses, such as spherical, plano convex, biconvex, or concave lenses.

7. Laser direct writing super lens:

   1. Principle: Using laser direct writing technology to manufacture superlenses, the design pattern is first converted into a digital signal, and then the laser beam is controlled by a computer to engrave on the substrate.

   2. Application areas: optics, microelectronics, biomedical and other fields, such as manufacturing high-resolution optical microscopes, optical sensors, micro nano optical components, biochips, etc.

In summary, laser lenses play an important role in multiple fields, and through their unique functions such as focusing and beam expansion, they have achieved a wide range of applications from laser cutting, welding, marking to lighting, scientific research, and more. With the continuous advancement of technology, the performance and application fields of laser lenses will continue to expand.
