Latest Patents

Among his latest patents, the "Asperic Surface Test Fixture" stands out. This optical surface apparatus is designed to handle aspheric surfaces by utilizing direct measurement of the blur circle created by the test surface. The device employs a collimated light beam that includes the test surface in its optical path, directing it to an ultimate focal point. An apertured screen with varying diameters is positioned at this focal point, allowing a light detector to measure light intensity based on aperture size. The design incorporates a folding mirror to maintain a compact structure, and it can accommodate different wavelengths of test energy with appropriate adjustments.

Another significant patent is the "Immersed Reticle," which features a low reflectance reticle immersed in optical cement between transparent substrates. A copper reticle is vacuum deposited on one substrate and treated to enhance its anti-reflectance properties. This reticle is then cemented to a second substrate, providing superior anti-reflection capabilities while protecting it from mechanical damage. The immersed reticle can also be integrated between elements of a compound lens.
