AuSn Thin-Film Technology and AuSn Pre-deposited Substrates for Optoelectronics
Wed, Aug 25, 2021 10:00 AM - 11:00 AM EDT
AuSn thin film is a critical technology to enable an optoelectronic device to ensure durability, anti-oxidation ability and reliability compared with Indium, SnPb, SnBi, and others. In this webinar, Allen Liu of Focuslight Technologies Inc. explains the design, key processes, and application data of high-power laser diode devices. Presented by FocusLight Technologies Inc.

Freeform Optics for Imaging: Mid-Spatial Frequency Errors
Thu, Aug 26, 2021 1:00 PM - 2:00 PM EDT
Residual mid-spatial frequency (MSF) surface errors are common byproducts of the computer-controlled sub-aperture manufacturing techniques needed for fabrication of freeform optics. In this presentation, Thomas Suleski, Ph.D., provides an overview of MSF surface error signatures, specification methods, and performance impacts. Part 3 of the 2021 Freeform Optics Series.
