My name is Adam Palmentieri, and I'm an applications engineer with Hamamatsu Corporation, which is a subsidiary of Hamamatsu Photonics in Japan. Hamamatsu is one of the leading manufacturers of photonics solutions worldwide and is constantly creating new technologies or developing existing technologies to meet future developments for applications including medical imaging, semiconductor manufacturing, industrial inspection, and many others.
Our line of ultra bialkali and super bialkali photocathodes, with quantum efficiencies up to 45% around 350 nanometers, are a perfect example of these new technologies. Using these photocathodes, we can create convenient photon counting units, like this one shown right here.
Another technological innovation is our micro-PMT, which combines PMT and MEMS technology to create an ultra-small unit for use in point-of-care systems. Our hybrid photodetector, which is very similar to a standard PMT, also combines two technologies, PMT and APD technology, to create a unit that has excellent timing resolution down to 50 picoseconds, near 100% collection efficiency and little-to-no after pulsing.
In an effort to keep up with an expanding number of applications that require hand sensitivities in the near-infrared and infrared regions, our factory can provide near-infrared enhanced silicon image sensors with quantum efficiencies up to 40% around 1,000 nanometers.
However, if one requires enhanced sensitivities further in the IR as well, we can also provide short-wavelength InGaAs image sensors that cover 500 to 1,700 nanometers and eliminates the need to use two individual sensors. When requiring increased sensitivities in the infrared only, we can also provide back-illuminated InGaAs image sensors that have quantum efficiencies up to 75% around 1,600 nanometers.
We also offer a high-speed line rate InGaAs image sensor that may be used in OCT and industrial imaging applications. Finally, we also offer driver circuits for most of these image sensors. Besides our components lineup, our factory also designs and manufactures complete solutions, like the Quantaurus quantum yield measurement system. This system reduces overall measurements by providing instant quantum yields without the use of a reference sample.
Using this system, we hope to further our understanding of our materials photoluminescence properties and enhance the research and development of photovoltaics, organic LEDs, LED phosphors, quantum dots, and many other new technologies. Thank you for taking the time to look over our products.
