Today's electronic devices like cell phones, laptops, and medical devices present increasingly complex assembly verification challenges. These "hard" inspection problems push the limitantions of any visual inspection method—human or machine. Assembly verification requires inspection of multiple features simultaneously and at high speed. If not caught, subtle defects—such as misrouted cables, missing screws, or misaligned connectors—can escape and end up in customer hands causing latent failures. The cost of these failures can be severe in terms of returns and warranty claims, customer dissatisfaction, and damage to brand reputation. Learn how photometry-based methods offer new capabilities to solve the hard inspection challenges.

The most important part of any camera is the lens, which directs incoming light to capture an image that mirrors reality. Today's highly sophisticated lenses are the result of a long history of optical and scientific experiments stretching all the way back to ancient civilizations. In this blog post, we look back at a bit of that history, examine how modern compound lenses work, and preview some innovative lens technologies of the future.

Customers of today’s consumer electronics devices expect a flawless product out of the box. Scratched, dented, and otherwise imperfect products can result in costly returns and warranty claims. Worse, visible defects damage your brand’s reputation and future business. Device manufacturers have employed machine vision systems and human inspectors to protect the quality of their products. Now, Advanced Vision solutions allow you to apply photometry-based surface inspection techniques that match the precision and discernment of the human eye, at automation speeds.

Microdisplays—screens measuring less than two inches diagonally—have been used in applications such projection TVs, smart watches, and near-eye displays (NEDs). Offering very high resolution and brightness coupled with low energy use, they are poised to become more widespread as augmented reality devices, head-up displays (HUDs), and and head-mounted displays (HMDs) are gaining wider use in industries from consumer electronics, to medicine, to the military.

Luminance, illuminance, luminous flux, intensity, brightness...how do we describe the qualities and brightness of light? We explain and discuss the spectrum of electromagnetic waves, including both visible (light) and invisible (e.g., radio, microwave), and how to quantify them with photometric or radiometric measurements.
