20mm Collimating Lens 20*3 for Fiber Laser Cutting Machine
What is Fiber Laser Lens?
Fiber laser lenses are special optical components used in fiber laser systems, they are mainly used to control, focus, reflect or transmit the laser beam. These lenses are typically made of high-purity, low-absorption optical materials, such as fused quartz, calcium fluoride, or other special crystal materials, to ensure that the laser beam can maintain a high energy density and low loss as it passes through.
Fiber laser lenses are indispensable components in fiber lasers, they provide strong technical support for laser processing, communication, medical and scientific research and other fields by accurately controlling the transmission and reflection of the laser beam.

High transmittance and reflectivity:
Fiber laser lenses are made of high purity glass or crystal materials, with extremely high transmittance and reflectivity, which can effectively control the energy distribution and direction of the laser beam. The specific values of transmittance and reflectivity depend on the design of the lens and the choice of materials, and can usually meet the needs of fiber lasers for high-precision laser beam control.
High stability and durability:
Fiber laser lenses can work stably in harsh environments such as high temperature, high humidity and high pressure, and are not susceptible to optical distortion caused by environmental factors. Its material has good corrosion resistance and wear resistance, and can maintain the stability of optical properties for a long time.
Versatility:
The retaining cap essentially holds all of the consumable parts of the torch together. As temperatures at this end of the machine are extremely high, it's not just the parts creating and focussing the arc that are worn down; the component holding them together also degrades over time.
At our company, we offer a wide range of laser lenses, including protective mirrors, focusing lenses, and collimating lenses. Our lenses are crafted with high-quality materials and precision manufacturing techniques to ensure optimal performance and durability. Experience enhanced laser performance and accuracy with our top-of-the-line laser lenses.

Fiber laser lenses are used in this process to control the direction and energy distribution of the laser beam, ensuring the accuracy of the print quality.
3.Laser measurement:
In the field of laser measurement, fiber laser lenses are used to control the direction and energy distribution of the laser beam to achieve accurate measurement of parameters such as distance, speed and shape of the object.
4.Optical communication:
In the field of optical communication, optical fiber transmission and laser modulation technology are used to achieve high-speed data transmission. Optical fiber laser lenses are used in optical fiber communication systems to control the direction and energy distribution of the laser beam to ensure the efficient transmission and reception of optical signals.
