Optics Expert Witnesses
What is an optics expert witness?
An optics expert witness typically has an advanced degree and extensive experience and expertise in optical engineering, electrical engineering, physics, and/or materials engineering. Photonics expert witnesses can opine on matters related to solid-state physics, fiber optics, or quantum mechanics. Most often the expert witness chosen is member of an industry organization such as the International Society for Optics and Photonics (SPIE), the Optical Society (OSA), and/or IEEE. An optics expert witness should have a deep understanding not only of the technology, but also of the optics market dynamics, market growth, and competitive landscape.
What types of cases require an optics expert witness?
Optics, a branch of physics, studies the behavior and properties of light. Whether the case involves display optics, lasers, red dot sight, fiber optic cables, optical systems, or photonics, an optics expert witness could provide expertise in intellectual property matters, such as a patent litigation in federal court or a trade secrets dispute. It could be a patent infringement case in the District Court, an Inter Partes Review (IPR) in the PTAB, or a patent case or proceeding in the International Trade Commission (ITC).
What litigation support work might an optics expert witness be expected to perform?
In a litigation scenario, a technical expert can expect courtroom testimony, as well as other expert witness services such as depositions, prior art searches, research and authoring expert reports, forensic analyses, and related consulting activities. In addition, clients may seek an optic industry expert for pre-litigation consulting work. An engineering expert witness needs to not only have technical expertise, but also possess the ability to explain technology to lay people. In high profile cases, or litigation involving a significant financial stake, previous expert witness testimony experience is often a requirement.

This expert has evaluated lasers, published in scientific journals on laser effects, conducted experiments on the use of laser dazzlers by the military, and participated in the review of laser injury cases for the Air Force.
Based on general exposure principles involving a brief, inadvertent sweep from a nominal 5 mW 532 nm green pointer, an immediate aversion response, and no sustained fixation, such exposure would be well below established thresholds for permanent retinal injury. Causation would be highly improbable absent evidence of significantly higher actual power or prolonged exposure.
