Organic Displays Sputter to Life

The visible range, spanning around 380 to 700 nm, has longstanding use in photonics. Many materials have specific absorption, reflection, and transmission characteristics in this band, which are...

According to data from the National Highway Traffic Safety Administration (NHTSA), more than 75% of automotive-related pedestrian fatalities in the U.S. in 2021 occurred at night. This value is...

Here is something David Goldman, vice president of marketing for Lumus, never expected to come into the field of view of waveguides: Wine growers using augmented reality (AR) glasses to teach...

In 2017, Clay Bavor, then vice president of Google’s AR/VR division, spoke for all AR/VR device makers when he said, “We need pixels. Way, way more pixels.”1 The display industry...

The OG0TC from OMNIVISION is a backside illuminated (BSI) global shutter image sensor for eye and face tracking in AR, VR, and mixed reality consumer headsets and glasses. The 2.2-µm sensor is...

The OS05L10 from OMNIVISION is a 5-MP image sensor for industrial and consumer security surveillance cameras. Using the company’s OmniPixel®3-HS technology, the 2.0-µm pixel frontside...

Marktech Optoelectronics’ line of point source LEDs has expanded to include high sharpness green LEDs and additional red LEDs for reflex sights, riflescopes, sports optics, camera viewfinders,...

The LUXEON HL4X from Lumileds is a high output LED for outdoor and industrial applications such as stadium lights, streetlights, high bay luminaires, torches, and rugged portable devices. The LED has...

There is a growing market for imaging systems that provides an immediate, slow-motion view of a process that allows one to see events that happen too quickly for the human eye to perceive or...

Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...

Controlling and minimizing heat output is desirable in most lighting applications. For example, conventional incandescent light sources are very inefficient with only a small portion of the...

An integrating sphere’s function is to spatially integrate radiant flux (light). However, before one can optimize a sphere design for a particular application, it is important to understand how...

VCSELs have increasingly become a fixture in smartphone and consumer electronic applications such as proximity sensing or face recognition, and recent advancements have only made these compact lasers...

Microdisplays are essential for wearable AR/VR/MR devices, such as smart glasses. Emissive microdisplays, such as OLEDs or micro-LEDs, provide significant advantages in terms of form factor and power...

High-volume manufacturing of products such as smartphones, medical devices, and semiconductors all require laser processing during the manufacturing process. Industry and consumer demand for smaller,...

Flexible displays are here and are being exploited by companies like Samsung, Motorola (Lenovo), Xiaomi, LG, and (by Q4 2017) Apple. These displays, which are lightweight, thin, curved at the edges...

Laser texturing is a manufacturing process that involves using a laser beam to selectively modify the surface of a material, creating textures, patterns, or microstructures. This technique is...

Micro-LED (micro-light-emitting diode) refers to a technology that involves the use of very small light-emitting diodes to create displays and lighting systems. These LEDs are miniature versions of...

An optical filter is a device that selectively transmits or blocks specific wavelengths, or colors, of light. Optical filters are used to control the spectral content of light in various...

Computational imaging refers to the use of computational techniques, algorithms, and hardware to enhance or enable imaging capabilities beyond what traditional optical systems can achieve. It...

The new VirtualLab Fusion 2023 thrills with a firework of new features. In this webinar we give an overview of the new features and put them into context with the development strategy and technical...

In this month's Light Matters Extra, we give you an in-depth look at the relationship between researchers and scientists at the University of California Davis, and surgeons and clinicians at nearby...

In this month's Light Matters Extra, we take you to the grand opening of the Price Chopper Market 32 Capital Holiday Lights in the Park in downtown Albany, New York. We'll introduce you to the...

On this month's episode of Light Matters, we take you on a brief tour of the Higgins Laboratories at Worcester Polytechnic Institute (WPI). Quinsigamond Community College and WPI received a $4M grant...
