R&D interviews

A close-up look at our products and technology along with confidential accounts
Here we give a brief interview type of introduction with development stories by the engineers who did the research and development of the products and technology. These accounts include talk about some surprising hardships and also perhaps some really interesting discussions about future developments. This is especially recommended for those who want to know more about our products.

Stealth Dicing® Technology - Tracing its development path

Stealth dicing is a recent, innovative technology for internally irradiating silicon and sapphire material with a laser beam to form a modification layer at an internal position and cleanly cut the material with an externally applied force. Here engineers tell about innovative products we have launched in the expanding markets, along with related episodes and where its development is headed from here.

2-watt xenon flash lamp module

The world’s smallest new “face” has appeared in our lineup of xenon flash lamps that consist of a glass envelope filled with high-pressure xenon gas. This is a module type 2-watt xenon flashlamp that has an unusual cuboid shape and operates on battery power. Here we listened to the members talk about product development episodes where they made every effort to meet market needs.

DIGITAL CAMERA ORCA-Flash4.0 V2 

ORCA-Flash4.0

The development project of the ORCA-Flash4.0 spanned more than one and a half years. Since the start of the preliminary specification stage, Hamamatsu worked closely with researchers from around the Globe including Japan, Europe, North America and China to identify their application needs and demands for a scientific camera. The feedback from the researchers was given to our development team and the versatile ORCA-Flash4.0 V2 was the result.

LD Heating Light Source / LD Irradiation Light Source

New Methods of Plastic Welding and Soldering using Semiconductor Lasers

The combination of these two led in 2006 to the creation of the LD heating light source (LD-HEATER), which monitors temperature during laser processing. Now, in 2014, LD plastic welding and soldering is no longer a rare method. We spoke with five young members currently involved in the commercialization of monitoring equipment and LD light sources aimed at LD processing applications and mass production.

EX-mini compact excimer lamp light source

It’s handy! The EX-mini compact excimer lamp source comes in one space-saving package yet still delivers a stable high-output.

Hamamatsu provides excimer lamp light sources that are designed for production line use and incorporate special features not found in products of other manufacturers. We have also developed a compact excimer lamp light source named “EX-mini.” This is an easy-to-use one-package unit yet still delivers a stable high-output making the EX-mini a highly useful excimer lamp light source starting to take root in the market. The Ex-mini comes in a user-friendly design that allows you to start using it right away after purchase and so is opening up new applications of excimer lamps. We talked to 4 staff members who helped develop the EX-mini.

LIGHTNINGCURE® LC-L5G

Printers express and reproduce colors to an unbelievably real level to boost the basic product value. Among these, UV printers (printers using ultraviolet light to dry ink) are popular since they can print on almost any surface. The UV-LED light sources made by Hamamatsu Photonics are gaining a big name for themselves in the market of UV printers. Now, Hamamatsu offers the new linear irradiation type UV-LED unit ”LIGHTNINGCURE LC-L5G.” Compared to the conventional model LC-L5, the LC-L5G delivers drastically higher specs including 1.5 times the input power, 7 times the light output, and one-half the cost, yet its size is only one-third that of the LC-L5. We interviewed the development team members to find out how they succeeded in creating this new model that drew attention at home and abroad exhibitions.

Quantum cascade laser × (QCL) InAsSb (indium arsenide antimonide) photovoltaic detector

Optical measurement of gases, atoms, and molecules such as NOx (nitrogen oxide) and SOx (sulfur oxide) having absorption characteristics in the mid-infrared spectral range from 3 μm to 10 μm is the focus of a lot recent attention. Many equipment manufacturers are now designing products that focus on this mid-infrared spectral region. To meet the needs of these manufacturers, Hamamatsu Photonics is developing and producing in-house the light-sensing and light-emitting devices needed for making mid-infrared measurements. Hamamatsu Photonics offers these light-sensing and light-emitting devices in sets for particular applications. There are very few manufacturers in the world that can produce such devices. We talked to members in charge of developing those devices to ask about the sales and engineering strategies in the background.
