What is Powell Lens? Powell lens is a prism with a rounded roof which used to transform a laser beam into a straight, uniform line. It's not a standard lens that focuses on light, but rather one that creates a highly precise line of light. How Does Powell Lens Work It takes a single point of light from a laser and spreads it out into a straight line. Creating the line: As the laser beam passes through the lens's apex, the surface geometry splits the beam and spreads the light...

What is an Axicon and what does it do? An axicon is an optical element with a conical surface that transforms a collimated laser beam into a focal line and a non-diffracting ring-shaped beam. Creates a Focal Line: Unlike a normal lens that focuses light to a single point, an axicon refracts light to create a focal line or a series of points along the optical axis.This is achieved through the interference of light waves refracted by the conical surface. Converts a Collimated Beam into a Ring: When the light...
