LEDs White Papers
Photoluminescence and Electroluminescence Confocal Imaging of an OLED
The optoelectronic properties of an OLED device are mapped using an RMS1000 Confocal Raman Microscope in spectral and time-resolved photoluminescence and electroluminescence imaging modes. These techniques enable the characterization of the OLED in...
Measuring and Correcting MicroLED Display Uniformity
MicroLEDs unlock next-level display performance, but inherent variability between LEDs can result in visual quality issues that impede production volumes needed for commercialization. Imaging systems have been proven for microLED test and...
Light Changes Matter – with Optics, Lasers and Sensors
Jenoptik is a global OEM supplier of solutions and products based on photonics technologies with more than 25 years experience in the fields of optics, laser technology, digital imaging, opto-electronics and sensors. Our customers work in areas such...
Health and Sanitization through UV Lighting
With increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it. Determining the amount of UV energy the light source emits onto the...
Light-Emitting Diodes: A Primer
This article will provide an overview of the LED operation and a brief look at the industry. Various types of LEDs, the corresponding wavelengths, materials used in their composition, and some applications for the specific lamps will also be...
A Short Introduction to Shortwave Infrared (SWIR) Imaging
SWIR imaging significantly extends the possibilities for industrial machine vision applications beyond the visible range. But while broadband light sources are adequate to illuminate some SWIR applications, narrow-band SWIR LEDs now deliver high...
Tolerance Analysis Tools Take the Guesswork out of a Colorful Illumination Design Problem
Tolerance analysis has largely been out of reach for illumination designers because of the time needed to perform the thousands of simulations required to get a meaningful statistical tolerance result, and because of a lack of built-in tolerance...
LED/OLED Design Using Mixed-Level Simulation
There has been extensive research to improve the design of light-emitting diodes (LEDs) and organic LEDs (OLEDs) to enhance light extraction efficiency, improve beam shaping, and allow color tuning. Due to the range and scales of geometric...
Time-Lapse Imaging with Lamp and LED – Stability vs Repeatability
Advancements in LED technology today enable LEDs to provide a compelling alternative to lamps for fluorescence microscopy illumination and have become increasingly popular. This article discusses the differences in stability between Lamps and LEDs,...
Use of White Light Fluorescence LED in long-term Live Cell Imaging Applications
Lamps have long been used in microscopy facilities to conduct time-lapse imaging experiments. Light uniformity, stability and sample exposure are key in generating reliable data. In this study, we evaluate an LED system (X-Cite 120LED) for our...
