Title: David M Heffelfinger: Innovator in Optical Technologies

Introduction

David M Heffelfinger is a notable inventor based in Oakland, CA, with a focus on advancements in optical technologies. He holds a total of four patents that showcase his innovative contributions to the field. His work primarily revolves around systems designed for high throughput analysis and optical interrogation of samples.

Latest Patents

One of Heffelfinger's latest patents is the Photon Efficient Scanner. This system is designed for optical interrogation of a sample, adaptable for multiple wavelength illumination and multiple wavelength fluorescent or luminescent light collection. The system utilizes coherent light from lasers to excite fluorescent or luminescent light from a target layer on a sample. The emitted light is collected from a selected depth by a reflective light collector, which transmits the collected light to detection optics. This innovative design allows for the separation of collected emitted light from illumination light, enhancing the efficiency of the scanning process.

Another significant patent is the System for High Throughput Analysis. This apparatus and method enable illumination light and collected emitted light to share a pathway before being physically separated. The optical configuration is designed to ensure that at the point of separation, the illumination light has a smaller cross-sectional area than the collected light. This adaptability allows for high throughput optical analysis of samples across a broad wavelength spectrum.
