What is a Powell Lens?

Introduction to the Powell Lens

A laser is a common optical device, widely used in laser communication, medical equipment, lighting, laser printing and other fields. In practical applications, it is sometimes necessary to adjust the laser, such as changing the shape of the laser or adjusting the light intensity distribution. This operation is called laser shaping. The Powell prism is a common laser shaping optical element, designed to convert a circular light spot into a linear light spot and change the light intensity distribution. This process transforms the Gaussian distribution of light into a uniform energy beam, also known as flat-top light.
