.: Vision Spectra Conference

Presentation: “Shrinking Pixels and Growing Sensors: Two Approaches for Increasing Resolution”
Presented by: Greg Hollows, Edmund Optics

The drive for continuous innovation in machine vision results in a constantly increasing demand for higher resolution. Sensor manufacturers can take two main approaches to meet demand: They can either shrink pixels, or increase sensor size. Both options come with tradeoffs, in terms of sensor performance, and with the imaging optics used with them. Because of fundamental limitations in the pixel size that can be successfully used with traditional imaging optics, the sizes of the sensor and mounting interface must increase to accommodate demands for higher resolution.

Greg Hollows, vice president of the Imaging Business Unit at Edmund Optics in Barrington, N.J., goes into the meaning of this trend for lenses; the challenges the trend introduces for builders of machine vision systems; and solutions for getting the most out of sensors and lenses.

The inaugural Vision Spectra Conference runs July 20 - 22. Registration is free for the event, which is offered exclusively online. For more information and registration, please visit www.photonics.com/vsc2021. Continued coverage of this inaugural event will also be available on vision-spectra.com and Photonics.com leading up to the conference.

Multi-Line Lasers or Laser Combiners: What Solution Is Best for Fluorescence Imaging?
Thu, Jun 17, 2021 10:00 AM - 11:00 AM EDT
Fluorescence based microscopy for high-resolution and high-throughput multi-fluorophore imaging typically relies on the use of several individual laser sources at different wavelengths, within the same instrument. Navigating the field of laser-based multi-color excitation options can be challenging. In this webinar Melissa Haahr and Helge Schmidt, Ph.D., of HÜBNER Photonics discuss the advantages of multi-line lasers and laser combiners with the aim to help identify the suitability of either solution for applications in fluorescence imaging. Presented by HÜBNER Photonics.

Laser-induced breakdown spectroscopy is the technology behind a newly developed forensic technique for tire chemical analysis. University of Central Florida’s Matthieu Baudelet, who introduced the method in a recent Applied Spectroscopy paper, explains the approach and how it is poised to enhance crime scene investigation. Pierre Türschmann, CEO of Interherence, talks about how the company is working to resolve the bottleneck of reproducibility in microscopy.
