High energy collisions of protons often result in production of collimated spray of particles, collected in what is termed as jets, from decay of ordinary quarks or gluons.

The failure of the paraxial and marginal rays passing through the same point on reflection at a spherical mirror or refraction through a lens is known as:A.

Gaussian to Flat-Top Transformation: The primary function of the Powell lens is to transform a collimated Gaussian beam into a flat-top beam profile, thereby facilitating uniform intensity distribution for more efficient processing and illumination. Customizable Divergence Angles: Available in a range of divergence angles, including 30°, 45°, 60°, and 75°, the Powell lens can be tailored to meet specific application requirements. This versatility allows users to optimize beam performance according to their unique needs. Enhanced Uniformity: With a non-uniformity of less than 30% within an 80% symmetrical range of the laser line, the Powell lens ensures minimal central hotspot and edge fading characteristics compared to traditional cylindrical lenses. Robust Design Options: Powell lenses can be engineered with varying dimensions and surface profiles, maximizing optical efficiency and performance across different wavelengths, including common laser outputs such as 633 nm.

Powell Lens: The Powell lens is designed to transform Gaussian beams into uniform flat-top beams, providing an even light distribution ideal for applications like laser cutting and illumination. It typically maintains a non-uniformity of less than 30% within an 80% symmetrical range, which helps minimize hotspots. In contrast, Cylindrical Lens: The cylindrical lens focuses or collimates light in one direction, creating a line focus or rectangular beam profile that may not be uniform across its width. This lens is commonly used in applications like barcode scanners and projectors but may exhibit significant hotspots and non-uniformity, especially with Gaussian input beams. In summary, the Powell lens is excellent for precise beam shaping and uniform light distribution, while the cylindrical lens is better suited for linear focusing tasks, with less concern for uniformity.
