Optical Fabrication and Testing of Dental Loupes


Wed. 20 Mar. 2024 at 7 pm, Zoom Meeting (open 6:45 to 8:15 CST) 


Speaker John Taylor has been in optical fabrication for over 45 years. Currently working for Quality Aspirators in Duncanville Tx. Quality Aspirators produces Medical and Dental loupes for dentists and doctors and dental hygienists. These are made under Q-Optics a subsidiary of Quality Aspirator. John will be giving a talk on the different type of loupes they fabricate along with a video tour of the optical fabrication shop.

Title: How Optics Enable Artificial Intelligence

Description: Recently, the release of DALLE-2 and ChatGPT has captured the imagination of the wider public of what AI can do. This has led to discussions on how AI will change the nature of education and work. Many people don’t realize that fiber optics are a key enabling technology for AI. In this talk I’ll show how high speed fiber optic links are used to connect clusters of GPUs together to build AI factories.


Presenter Bio: Dr. Earl Parsons is the Director of Data Center Architecture Evolution at CommScope. He joined CommScope in 2014 as a Principal Optical Engineer. Prior to joining CommScope Earl received an MS and Ph.D. in optical sciences from the University of Arizona and was a Senior Member of Technical Staff at TE SubCom, formerly known as Tyco Telecommunications. Dr. Parsons also served as an editor of the IEEE 802.3db-2022 standard. His interests include multimode and single mode fiber optic systems to enable artificial intelligence data centers.

A New Pediatric-Suitable Retina Camera, Presented by Mike Jones

A team of four pediatric PhD ophthalmology specialists and Mike Jones (retired optical designer for Lockheed Martin and Raytheon) is working to produce a new retina camera designed specifically for infants and premature babies having eye globe diameters on the order of 16-20mm, much smaller than adult eyes.  The camera covers a 60º portion of the retina centered on the fovea, and maximizes detection and diagnosis of abnormal arterial and venous blood vessel development.  Early detection of blood vessel abnormalities enables medical treatment that will help to restore normal blood flow to the retina and minimize the chances of permanent blindness.  The camera is primarily intended to be fielded in medically disadvantaged third-world countries.  Its cost will be roughly 10-15% that of existing retinal cameras, and the camera, control computer and software will be designed to facilitate medical staff training in these regions.
