What is beam steerer?

A beam steerer is a device used to adjust the direction or trajectory of a beam of light, typically a laser beam. This can be done by using various types of mirrors, prisms, lenses, or other optical components that can deflect or refract the light in a controlled manner. Beam steerers are commonly used in laser cutting and welding, medical and scientific research, and industrial applications such as material processing and inspection. They can also be used in communication systems, such as optical fiber networks, to help direct the flow of data. Some types of beam steerers are designed to operate in real-time, allowing for precise and dynamic control of the beam direction, while others may be used for more static applications where accuracy and stability are key.
