Hamamatsu Photonics

5th Technology Days


  • Welcome to Hamamatsu Photonics' 5th Technology Day 'Fresh from the lab' in Milan!


    29th November 2019.





    Palazzo delle Stelline

    corso Magenta , 61

    20123 Milan – Italy


    Technology Day (29th November 2019) from 9:30 -17:00


    With this year’s theme, “Fresh from the lab” Hamamatsu will introduce a range of technologies we have been closely working on in the following application areas; Analytics and NDT, MPPC/SiPM & 3D Imaging and VCSEL and Beam Steering.

    The day will offer a number of networking opportunities and we hope that the topics covered on the agenda will spark interest and debate amongst attendees. There will also be a range of demonstrations taking place highlighting a range of Hamamatsu’s technologies.

    At Hamamatsu we pride ourselves on meeting our customers’ needs and we hope Technology Days will offer a forum for discussion and an opportunity for us to learn more about the applications and products you are using in your given field.

    Dr. Tommaso Cervi

    Mega System


    Born on 5 July 1990, I had always a passion for research. I began my academic career at the University of Pavia, graduating in Nuclear and Subnuclear Physics with a thesis entitled: "Characterization of a SiPM at cryogenic temperature, in view of a development of a scintillation light detector into liquid noble gas TPC ". Then I obtained my PhD in Physics in Pavia on 18 January 2019, with a thesis entitled " Development of an innovative photodetector for liquid argon applications: the SiPMs Single Channel Array ". It is one year I am working as a researcher at Mega System srl, a company located in Bareggio (MI) which manufactures equipment for the analysis and sampling of polluting substances produced by factories.


    MPPC array to measure nitrogen oxides in pollution gases



    To measure the Nitrogen Oxides (NOx) emitted into the atmosphere by ducts or chimneys, the European Standard specifies as Standard Reference Method (SRM) the Chemiluminescence technique. This method consists on the reaction between the sample gas containing Nitrogen Monoxide (NO) and the Ozone produced by an Ozone generator, which produces a light emission (chemiluminescence) proportionally to the NO concentration.

    Because of the Nitrogen Oxides are, generally, composed by about 90% of NO and 10% of Nitrogen Dioxide (NO2), the European Standard includes also the method to measure the concentration of NO2. In this case the sample gas should pass through a NO2 to NO converter which consist on a heated chamber which contains a catalyst material able to reach a conversion efficiency of at least 95%.

    The NO chemiluminescence emission spectrum is peaked around 1200 nm with a lower cut-off around 600 nm. To avoid the detection of light produced by other reactions of other gases with the Ozone which emit, usually, into the visible wavelength range, an optical filter at 600 nm is used.

    Nowadays because of the emission range of interest, almost all the instruments use a Photomultiplier Tube (PMT) to detect the produced light.

    Due to the recent developing of the semiconductor technology specially regarding the light detection, in our application we are developing a system based on an MPPC array to replace the PMT. The reason of this choice is based on the possible advantages that an MPPC gives, such as the smaller size, the versatility of the possible configurations and the higher resistance to mechanical stresses. All these features are very useful to apply this technology into portable multi-gas analysers.


    Dr. Cristian Previtali



    Cristian Previtali, born in August 1978, has a Master's degree in Electronic Engineering – "Microelectronics and Instrumentation" specialization – obtained “cum laude” in 2003 with a thesis focused on the physical characterization of Flash memories. He has been working in Cefriel since 2004 and its main activities concern the ideation, development and design of smart products for various market sectors, from automotive to biomedical, from white goods to lighting.


    Smart Solutions Enabling Digital Innovation



    Cefriel is a digital innovation center that creates products, services and processes, participates in international research programs and develops digital culture and skills.​ Exploiting the link with universities and selected technology providers, Cefriel is the company’s best partner when the focus is on the application of know-how and technologies to address challenges, opportunities, and expectations in digital innovation.   
    Some examples of innovative solutions developed in recent years by Cefriel have been based on the use of spectrometry to recognize materials in order to enable new possible business scenarios. The first experience of this kind was made for a European manufacturer operating in the household appliance sector, who wanted to offer his customers a low-cost portable device in order to recognize the fabrics present in the laundry and choose the most appropriate washing machine cycle. Exploiting the skills offered by the Chemistry Department of the Politecnico di Milano and the technology offered by Hamamatsu Photonics – in particular the MEMS FPI spectrum sensors operating in the Near Infra-Red region – it was possible to develop a low-cost portable device that could recognize the different types of fabrics in the laundry. From this first experience Cefriel has carried out new internal initiatives, always based on Hamamatsu Photonics technology, aimed at materials recognition - from the discrimination of plastics in a waste disposal center to the detection of the deterioration level of food - in order to enable new services for potential new customers.
