Navigating the MIR market

Mid-infrared measurements have recently become a hot topic in the photonics industry and for good reason: so much valuable information lies within interactions with longer wavelengths. Capability, cost, and complexity make selecting the proper components a tough balancing act - this presentation aims to give some insight into navigating this space.

Introduction to infrared detectors

A great deal of information about the physical world, from cosmos to DNA, comes to us in the form of infrared radiation (IR). In addition, man-made systems, such as automotive LiDAR, thermal-vision cameras, or communication networks, rely on IR for successful and optimal operation.

Do dim things - why low light imaging capabilities enable advances in research and medicine

The past decade of camera development ushered in a new era of low light imaging that was previously unfathomable. EMCCDs enabled the first precision localization super resolution experiments.

Challenge of circuitry to a successful image sensor implementation

It is only a starting point to the success of acquiring high quality images from an image sensor when you selected an image sensor from a reliable supplier, even though the sensor specifications can meet all of the requirements in your mind.

Advances in testing and calibration of modern optical sensors

Electronics used in home and professional settings are increasingly able to sense and respond to their operating environments to assist and delight the user. Optical sensors are one great example of this. Modern electronic devices use sophisticated optical sensors and algorithms to perfect the images on displays, in pictures, and in videos.

Extreme ultraviolet light sources supporting next-generation lithography

Moore’s Law continues to drive semiconductor integrated circuit shrinks down to 3 nm and below and an increased feature density without passing the cost to the consumer.

See beyond visible: short wavelength infrared introduction and applications

Are we seeing what we see? We've been relying on visible light to differentiate objects and identify items, but the surface and its color sometimes could confuse us. Beyond the visible spectrum, many components are transparent in SWIR light that are opaque in visible light. SWIR brings out details beneath the surface you would otherwise miss.

Introduction to image sensors

Capturing and recording an image is a fundamental process of data taking in nearly all branches of science and medicine. It has evolved from hand sketching of the scene through imaging based on photo-chemistry of silver compounds to the present-day electronic imaging. Electronic image capture, manipulation of images, and image transmission have become efficient and inexpensive allowing a wide adoption of the techniques outside of science; in areas such as entertainment, communication, education, or retail electronics – the cell phone. CCD and CMOS are the two most commonly used image sensors and they will be the focus of this webinar.

X-Ray technology for NDT applications

X-ray technology advancements have steadily increased since they were discovered over 100 years ago. Recent improvements in both x-ray source tubes and detectors are ushering in newfound applicability of this technology as a critical-to-quality tool for non-destructive testing in growing markets such as: 3D metal printing, food inspection, electronic components, and industrial CT.

An encounter with light generating devices

Light-generating devices use many different technologies to generate light over a broad spectrum range and with varying characteristics.

Understanding spectrometer signal-to-noise ratio

Learn why one of the most important parameters when selecting, and implementing a spectrometer is the signal-to-noise ratio (SNR). While the definition of SNR varies greatly within the photonics industry, this course defines a commonly used methodology and gives practical examples of the same.

General image sensors and spectrometers

There are many spectrometers on the market for various spectroscopy applications. In this presentation, you can learn what’s unique about Hamamatsu’s spectrometers. We are not just a run-of-the-mill supplier; we are uniquely positioned to provide every aspect of spectrometer technology. Hamamatsu is well-known as a quality sensor (CCD, CMOS) provider, and now also for MEMS/MOEMS solutions including transmission gratings and nano-imprinted surface-enhanced substrates (SERS) and micro-spectrometers. We combine these unique technologies to manufacture portable Raman and other optical modules. To cover the NIR, many are turning towards MEMS-FPI tunable filters, the MEMS-FTIR engine, or compact InGaAs-based thin flat spectrometers, forming low-cost handheld spectroscopy solutions.

Photodetection in flow cytometry

In flow cytometry, the light scattered off an interrogated cell contains information about the cell. The role of a photodetector is to transform this information from light signal to electrical signal. This task makes a photodetector an indispensable component of a functioning flow cytometer. Transformation of information from one domain to another is never lossless. A photodetector, together with the front-end electronics, will always introduce some degree of noise and signal distortion, which impacts ubiquitous-to-flow-cytometry scattered plots. Absent of a perfect photodetector, a practitioner can choose between devices such as a photodiode, avalanche photodiode, photomultiplier tube, or silicon photomultiplier. However, each of these has unique opto-electronic and performance characteristics; therefore, the optimal performance - the smallest impact on the scatter plot – should be the guiding principle in the selection process of the photodetector.

Solid state automotive LiDAR: physics principles, design challenges, and new developments

The automotive industry and academia are actively engaged in applied research developing systems needed to make cars fully autonomous. One such system is LiDAR: it is needed to provide high-definition 3D information of the car’s surroundings at the video rate and up to a distance of about 200 meters. A complete design of a functional LiDAR is proving to be elusive, with beam steering and photodetection presenting the greatest engineering challenge.

Introduction to photodetectors part 2

Photodetectors are essential components in a vast array of modern scientific and commercial instruments and devices; technological progress will make them even more ubiquitous. Understanding their opto-electronic properties, regimes of operation, circuit requirements, and noise characteristics is essential to a practitioner to make a proper photodetector selection for a given application.
