Title: Denwood F. Ross: Innovator in Ophthalmic Lens Technology

Introduction

Denwood F. Ross is a notable inventor based in Green Cove Springs, FL (US), recognized for his contributions to ophthalmic lens technology. With a total of 4 patents, Ross has developed innovative methods and apparatuses that enhance the production and measurement of contact lenses.

Latest Patents

One of Ross's latest patents is for a method titled "Scanning laser demolding of ophthalmic lenses." This invention involves an apparatus designed to remove molded ophthalmic lenses from their molds using intense electromagnetic radiation. The method employs galvanometer-driven mirrors to create a predetermined scanning pattern, which causes differential expansion of the mold materials. This process effectively breaks the adhesion between the polymerized lens and the mold, facilitating easier separation. The careful management of temperature gradients ensures minimal energy transfer to the lens, preventing thermal decomposition.

Another significant patent by Ross is focused on "Lens parameter measurement using optical sectioning." This arrangement allows for precise measurement of contact lens parameters by immersing the lens in a saline solution and using optical elements to generate a line of light. An imaging camera captures the scattered light, enabling the determination of critical parameters such as diameter, front and back radius of curvature, and center thickness. This innovative approach can also measure additional characteristics, enhancing the understanding of lens performance.
