Fundamental research & Applied research
This page introduces you to time-resolved spectroscopy which utilizes the high transmittance of near-infrared light through a living body to capture the spreading state of pulsed light irradiated within the tissue of a living organism at a specified wavelength. It also describes related products using this technology.
Delayed luminescence is a phenomenon in which the light emitted due to light stimulation slowly occurs in several seconds to a several dozen seconds compared to fluorescence. Measurement of this phenomenon is the focus of much recent attention since it is a useful way to evaluate effects of chemical substances on the environment.
The LCOS-SLM is a reflective type spatial light phase modulator for freely and precisely changing the phase of the light. This page introduces you to our optical phase modulation technology that is utilized in laser processing and measurement of high resolution fundus images by wavefront correction.
Hamamatsu Photonics has turned to MOEMS technology which combines elementary technology of opto-semiconductors and electron tube devices with MEMS technology to produce optical devices having yet higher performance and sophisticated functions. Here we introduce you to opto-semiconductor device technology and MEMS technology, as well as some applications of MOEMS technology.
Photomultiplier tubes made by Hamamatsu Photonics boast a top market share even in countries across the world. Producing a high degree of vacuum is an essential part of their manufacturing process. Here we give a brief introduction to technology for generating a vacuum state which provides vital support for photomultiplier tube manufacturing.
Photomultiplier tubes, which are our major products, are used to detect low level light and convert it into electrical signals. Here you can get a brief look at the technology and principle of photocathodes that convert light into electrons, as well as photomultiplier tubes using different properties of photocathodes.
Vacuum vessels or tubes used for high sensitivity photomultiplier tubes and light source lamps require glass with excellent air-tightness and light transmittance, etc. This page introduces you to glass processing technology developed by Hamamatsu Photonics through long years of experience to produce photomultiplier tubes and light source lamps.
Microfocus X-ray sources from Hamamatsu Photonics have a very small focal point that helps produce sharp, enlarged X-ray images with no blur. On this page, we introduce X-ray source technology used for a large number of applications including inspection of electronic circuit boards, industrial products such as aluminum die cast parts, and medical products.
Hamamatsu Photonics produces light sources that emit light at different wavelengths by artificial plasma created by electrical discharge. In this page we introduce you to discharge technology that helps generate the “non-flickering light” required in many applications such as the environmental, medical, and semiconductor manufacturing fields.
Based on the cutting edge spectroscopy and related technology, Hamamatsu Photonics is constantly at work developing a variety of high-accuracy film thickness measurement devices to match diverse customer needs. This page introduces you to spectroscopic and interferometric technology that supports a wide range of thickness measurements ranging from thin films to substrate thicknesses.
Stealth dicing technology is a “completely new wafer dicing technology” utilizing a laser specially developed by Hamamatsu Photonics. There is almost no kerf loss and chipping during dicing, so this high-quality cutting technology is now in wide use for semiconductor wafer dicing. Here we introduce you to the theory and special features of stealth technology along with its developmental roadmap we have planned.
