Presenter Description: 

Matthias Sachsenhauser holds a degree in experimental physics, with a focus on semiconductors and bio-nanotechnology. After obtaining his PhD at the Technical University of Munich, he started working as a technical sales engineer at Hamamatsu Photonics Deutschland GmbH in 2016. While his main expertise lies on optoelectronic components for industrial applications, a particular focus of his work is also dedicated to growing sales of laser-driven light sources in Europe by identifying new target applications and markets.

Laser-driven light sources: Advanced illumination for optical sensor characterization and imaging applications

Today’s cutting-edge research and manufacturing applications in materials sciences require light sources capable of delivering bright and highly stable light over long lifetimes.

The laser-driven light source (LDLS) technology is able to provide ultra-high brightness over a broad wavelength band (ranging from DUV to IR) making it a powerful and extremely long-lifetime alternative to conventional deuterium, short-arc xenon or tungsten-halogen lamps in advanced applications, such as semiconductor metrology and inspection, thin film monitoring or hyperspectral imaging. This presentation provides a fundamental introduction into the LDLS technology itself, along with a brief product overview and selected application examples.

In addition, the latest system-level light source developments harvesting the LDLS technology will be discussed, with a particular focus on the laser-driven tunable light source (LDTLS) and the Chromatiq Spectral Engine (CSE). While the monochromator-based LDTLS allows to generate wavelength tunable light with unrivaled scanning speed and accuracy, the novel CSE can emulate real-world lighting conditions by precisely controlling the spectral content of emitted light. Among other applications, these unique light sources enable efficient testing and calibration of optical sensors in high-volume production environments.

Benchmarking of photon counting and number resolving techniques in cameras

Most imaging applications using quantum illumination are enabled through single photon counting detectors. Detectors capable of spatially detecting single photons – i.e. cameras – have been used for more than 4 decades. The output of those cameras is binary in nature, since their structure allows for the reliable discrimination between 0 and 1 photons in each pixel, but not between other numbers.

Since the first commercial camera providing photon number resolving capability was recently released, some of the key performance differences between single photon counting and photon number resolving cameras will be presented – both in a fundamental discussion as well as in specific implementations.

Beyond pico-seconds – Hamamatsu Photonics new Universal Streak Camera

Hamamatsu Photonics as a big player in the market of optoelectronic sensors, light sources and components offers various spectroscopic techniques and instruments. One of the most outstanding instruments are the streak cameras designed as best direct measurement method for ultra-fast light phenomena.

Streak camera systems are perfect instruments for simultaneous time and wavelength resolved measurements and therefore beating the traditional TCSPC method in many fields. No other direct spectroscopic technique offers such a flexible measurement range (ms down to ps) with ultrafast (<600 fs) time resolution. Various models cover a wide spectral range from UV to NIR and all come with single photon sensitivity, a large dynamic range and high repetition rate complying with even the most demanding applications. Additional function expanding units adding a second time axis and blanking possibilities even broaden the possible applications further.

These can range from typical time resolved fluorescence measurements, raman spectroscopy even to transient absorption and therefore applying perfect for mechanistic studies in physics as well as in chemistry. The streak camera is capable of single shot experiments as they are typical in discharge and high energy physics, up to several hundreds of MHz in repetition rate as they are typical for linear accelerator and synchrotron facilities. Other typical application fields are LIDAR, photon correlation, nuclear fusion, optical communication as well as investigating quantum devices.

Image sensors from visible to near infrared spectrum

With the continuous increase in volume and quality, it is becoming more and more important to use instruments for vision systems in production lines. In this presentation you will learn more about the key technical features and Hamamatsu Photonics` latest CCD and CMOS products, covering the UV and visible spectrum to the new frontiers of sensors with near and mid-infrared detectors for industrial applications.

Presenter Description: 

Luigi Ghezzi is Technical Marketing Engineering at Hamamatsu Photonics Europe, where he focuses on detectors ranging from ultraviolet, visible to near and short infrared.

After graduating in physics at Federico II of Naples in 2010, specializing in solid-state physics, optics and optoelectronics, Ghezzi began his career in the automotive sector, where he expanded his optical skills in industrial processes and the use of silicon-based sensors in the automotive and industrial sectors. At Hamamatsu Photonics Europe Ghezzi is focused on the Si and InGaAs PD&APD and image sensor product families.

Spectroscopy at ultra-high dynamic range, high sensitivity and high spectral resolution

Spectrometers typically rely on the comparisons of signals. But the intensities mustn’t differ too much, to fit into the instrument’s dynamic range. Otherwise, filters or sequential measurements become necessary. Hence, samples with high densities or processes with simultaneous excitation and emission such as plasma monitoring or photoluminescence are difficult to access for spectroscopy.

Our innovative OPAL-Luxe spectrometer now offers a solution as it enhances the dynamic range from a few tens of thousands to an unprecedented range of 2.5 million to 1.
