Title: Innovations of Richard A Register
Introduction
Richard A Register is a notable inventor based in Princeton Junction, NJ (US). He holds a total of six patents, showcasing his contributions to the field of technology and medicine. His work primarily focuses on advanced laser applications and materials science.
Latest Patents
One of his latest patents involves cataract removal using ultra-short pulse lasers. This innovative system and method replace a lens to treat cataracts by ablating cataractous tissue through a multi-photon process using focused, ultra-short laser pulses. The process requires an energy intensity between 10 to 10 W/cm, achieved with femto-second duration pulses and 50 micro-Joules of energy. This allows for material disruption with minimal heating or shock. The ablated material is then removed through a micro-channel leading to the surface of the eye. After removal, a pre-polymer fluid is injected to fill the void, which polymerizes into a gel that matches the transparency and Young's modulus of a healthy lens.
Another significant patent pertains to short-wavelength polarizing elements and their manufacture and use. Traditional gold wire grids have been ineffective for shorter wavelengths due to their large period. However, Register's invention allows for the fabrication of grids with periods of a few tens of nanometers. These grids can polarize visible and ultraviolet light, leading to various applications in semiconductor fabrication and nanolithography.
