Beam Profiling: What Is Your Laser Not Telling You?
Beam Profiling: What Is Your Laser Not Telling You?
While it may seem intuitive that turning up the power on a laser will produce faster results in a materials processing operation, beam measurement tools often reveal that this only distributes the laser’s energy over a larger area, resulting in a lower irradiance (energy per unit area) on target. Today’s beam profiling instrumentation allows end users to tune their laser processes to achieve a precise irradiance that is intense enough for the task, but not so intense that a weld, for example, overheats and renders less optimal results.

The Food Industry’s Appetite for Hyperspectral Imaging Grows
If the old maxim “you are what you eat” has any truth to it, then it becomes critically important to ensure that the food you consume is safe and of suitable quality. To this end, the U.S. Department of Agriculture spent $1.1 billion in 2019 to support food safety and inspection operations, while state governments and industrial producers funded additional food safety and quality assurance efforts. Despite this, the Centers for Disease Control and Prevention estimates that 48 million Americans get sick every year from food-borne pathogens, foreign objects found in food, or poor-quality product. As a result, industry and researchers continue to seek new ways to improve the reliability, speed, and cost of food inspection.

Camera Selection for Low-Light Imaging
Camera Selection for Low-Light Imaging
Fluorescence microscopy is a broadly used term, with applications ranging from basic life science, such as time-lapse cell viability assays, to sophisticated techniques in which a very few photons or single molecules are detected and localized by specific high-end hardware and software. It further extends to even more sensitive biochemistry detection methods that leverage, for example, chemiluminescence and bioluminescence. Low-light imaging technology is instrumental to all of these microscopy applications, and often finds use in macroscopic optical systems. Although fluorescence microscopy technology is quite mature, camera selection for specific applications remains challenging. It can be complex to design a cost-effective optical imaging system that is optimized for a particular task, and end users can benefit from an overview of the major technical aspects that should be considered when choosing imaging components.

Shrinking Pixels and Growing Sensors: Two Approaches for Increasing Resolution 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.

Nitride-Based MicroLED Emits Pure Red Light
Nitride-Based MicroLED Emits Pure Red Light
MicroLEDs are a favored technology for next-generation displays, given their (small) size and energy efficiency. However, each LED is only able to emit light over a narrow range of colors. Devices can be created that combine many different LEDs that each emit a different color. Full-color displays can be created by combining red, green, and blue microLEDs. The problem, however is that an LED’s emission color is determined by the material properties of the semiconductor. A microLED developed at KAUST is able to efficiently emit pure red light and could help in the quest to develop full-color displays based on a single semiconductor.

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.
