Alluxa Educational Webinar Series

COVID-19 Prevention and Testing

Solutions from Optics and Imaging

This webcast was originally broadcast on July 23, 2020 and is now available for on demand viewing.

The rise of the novel coronavirus, and the spread of the COVID-19 sickness, are central challenges facing the world today. Preventing the spread of and testing for COVID-19 are the focus of a massive worldwide research, development, and deployment effort -- and some of the first, and subsequently most widely, used approaches have been based on prevention and testing using optical imaging. This webcast consists of short presentations by three leading precision optics and imaging companies: specialists from Ophir, FLIR, and Alluxa will provide an overview of how optical technology is being used to help contain, and to hopefully help diminish, the COVID-19 pandemic. You will leave this webcast with an increased understanding of how our industry is providing solutions to this crisis.

Cost: Register to attend.
Presented by: Dr. Rance Fortenberry, Director of Technology, Alluxa and others

Recent Advances in Thin Film Filters for Lidar Applications

An Invited Talk with Dr. Rance Fortenberry

In this talk given at the Society of Vacuum Coaters TechCon 2019, Dr. Fortenberry discusses the optical filter characteristics that are essential to the performance of a variety of Lidar systems and applications.

Improvements in cost, performance, and availability of key components have driven the diversification of Lidar systems in fields such as autonomous vehicles, atmospheric science, terrain mapping, and oceanography. Optical filters, which are critical components of many Lidar systems, are used either at the receiver to isolate the signal from background light or at the transmitter to clean up the spectral characteristics of the laser. The latest developments in thin-film optical filter technology pertaining to temperature dependence, acceptance angle, bandwidth, spectral squareness, transmission, attenuation, and spectral uniformity are outlined in order to illustrate the effects of each of these properties on Lidar system performance.

A Guide to Tolerancing of Optical Coatings

A Webinar With Dr. Angus MacLeod, President and CEO, Thin Film Center.

In this webcast on tolerancing of optical coatings, Angus Macleod of the Thin Film Center attempts to answer the primary question, "Can this coating be successfully manufactured?" Macleod discusses the range of tolerancing techniques and their development over time, including the concept of sensitivity; the advent of Monte Carlo methods; and, supplementing the Monte Carlo models and replacing the idea of sensitivity, the concept of performance envelopes that represent the full range of performance variation that can be caused by layer thickness errors of any magnitude. He discusses how the idea of tolerances cannot be separated from the process of monitoring during coating deposition, and talks about how process simulation using Monte Carlo principles is the ultimate technique, sometimes called computational manufacture, and how performance can be perturbed by other errors in manufacture such as departures from uniformity.

Alluxa designs and manufactures next generation, hard coated optical filters using a proprietary plasma deposition process in Santa Rosa, CA. Alluxa’s unique, purpose-built deposition platform and control systems were designed, developed, and built by our team in Santa Rosa, CA to address the demanding requirements of the next generation of systems and instruments.
