Laser Optics - Focus Lenses

Laser optics are optical components and systems that are used in laser systems. These components and systems manipulate the laser beam to control its direction, intensity, focus, and other characteristics. One type of laser optic is a focus lens. A focus lens is a lens that is used to change the focal length of a laser beam. This allows the beam to be focused to a smaller spot size, which can increase its intensity and enable it to perform certain tasks, such as cutting or welding materials. Focus lenses are typically made from materials such as glass or synthetic sapphire, which have a high refractive index and are capable of transmitting laser light without significant loss or distortion. They may be coated with special coatings to enhance their performance and reduce the effects of thermal distortion or other factors. Focus lenses are an important part of many laser systems, and are used in a wide range of applications, including manufacturing, medicine, and scientific research.
