Hamamatsu Photonics


Topics Overview

  • Showcases on our booth

    Over the past fifteen years, we’ve introduced many major technologies at Laser - World of Photonics, including Laser systems for plastic welding, MEMS devices, award-winning micro-spectrometers, and scientific CMOS cameras, to name but a few.

    We are continuing this tradition at Laser - World of Photonics 2022, so check this page to discover what new technologies and products we have been developing.

  • LCOS - Spatial Light Modulators

    Flexible Laser Beam Shaping in all its Excellence!
    High Laser Powers - FAST - Highly Precise - Highly Efficient


    Our LCOS-SLM (optical phase modulator) is a device that can freely control the phase of the laser beam electrically. The phase of the laser beam can be controlled in two dimensions by a structure in which liquid crystals are sandwiched between a CMOS chip and a transparent electrode deposited on a glass substrate. The digital images output from the PCs are converted to analog signals by a dedicated drive circuit, and voltage is applied to the pixel electrodes on CMOS chip. This voltage tilts the liquid crystal molecules and changes the refractive index of the liquid crystals, thereby controlling the phase of the light irradiated to each pixel.


    Spatial Light Modulators that can control the phase of light with high accuracy are used in a wide range of applications, from research applications such as the generation of optical vortices, atom-traps in quantum optics experiments to industrial applications such as aberration compensation in microscopic observations and laser material processing such as e.g. single shot QR-code marking by multipoint branching.


    In recent years, LCOS-SLMs have been drawing attention as a tool for creating new added value in laser applications by combining a laser beam with a dramatically improved power and repetition rate with a phase control technique that branches the focal point into multiple points and thus enables higher processing speeds.



  • LiDAR

    LiDAR (Light Detection and Ranging) is a remote sensing technology that measures distance by irradiating a laser light on objects and catching the light reflected back with a photosensor. In recent years, great progress has been made towards realizing fully autonomous automobiles.


    LiDAR has high azimuth resolution, making it possible to find the distance, shape, and relative positions of surrounding vehicles, pedestrians, buildings, and other objects with high accuracy. This technology has attracted attention for its potential in various applications, including ADAS (Advanced Driver-Assistance Systems) and AGV (Automatic Guided Vehicles).

    We offer a variety of devices for LiDAR, including pulsed laser diodes as light sources and Si APDs, InGaAs APDs, and MPPCs (SiPMs) as photosensors. We also offer custom support for these devices.


  • Semiconductor Laser for thermal processing

    The lower price due to higher output power of semiconductor lasers has expanded the application of laser processing. However, there is still anxiety about reliability and quality control, which block dissemination of laser processing.


    We believe that to understand the process for stable laser processing is essential to eliminate such anxiety and focuses on visual control of the processing. Hamamatsu Photonics offers various kinds of semiconductor laser applied products which can be used in wide range of application from R&D to production site.


  • IR Technologies

    Infrared detectors and emitters are widely used in diverse fields including optical measurement in the analytical, industrial, and medical applications, but also in the communication, agriphotonics, physical and chemical science etc.

    Based on long involving photonic technologies, Hamamatsu provides a wide variety of infrared detectors and emitters on different integration levels with brand-new technologies, on-going advancements or to bring traditional technologies to the next level in order to fulfill ideally the requirements from our customers. Further improvements are bringing new alternative technologies onto the market.


  • OCT

    OCT is a technology that uses the coherence of light to measure distance in the direction that light travels. Near-infrared light is shone on the sample, and the light scattered and reflected back by the sample is combined with reference light passing through a fixed light path inside the OCT device.


    By detecting the light interference signal generated in this manner, a one-dimensional signal in the depth direction is obtained. It is possible to obtain tomographic images by continuously scanning the position of light incidence on the sample.


  • Cameras

    Our cameras are designed to deliver beautiful and reliably quantitative images even in the most demanding of applications.


    We have a diverse lineup of cameras that support a wide range of wavelengths from X-rays to the near-infrared and support of variety of applications.


  • Energetiq

    The Laser-Driven Light Sources or LDLS is an innovative light source developed by Energetiq Technology inc. in the US, which is a subsidiary of Hamamatsu Photonics K.K. LDLS is the only light source in the world that utilizes a focused laser beam to generate and maintain plasma between the discharge electrodes in the xenon gas filled bulb.


    Energetiq manufactures advanced, next generation light sources with breakthrough, patented technologies, including our ultra-bright Laser-Driven Light Source (LDLS®) and Electrodeless Z-Pinch™ EUV source. Our light products generate high brightness across a broad spectral range, from soft x-ray to the deepest UV, through visible and into the NIR, and deliver efficient light collection in a reliable, compact package.


    Match Any Light Spectrum, or Design Your Own

    The Chromatiq Spectral Engine™ (CSE) is a sophisticated light source capable of matching real-world lighting conditions, emulating illuminant standards, and creating custom spectra.

    The CSE offers unparalleled spectrum match accuracy as well as repeatability and speed when switching between spectra to optimize optical testing and calibration procedures in the production environment.
    The CSE is built around the high radiance and stability of the Laser-Driven Light Source (LDLS™). The performance of the LDLS, combined with the innovative design of the CSE system, enables consistent high-fidelity spectrum matching, rapid switching between selected spectra, and stable color content at various intensities.


  • Spectrometer / Spectrum Sensors


    Mini-spectrometers are compact and low cost spectrometers (polychromators). We offer over 20 different types of mini-spectrometers covering the spectral range from UV to NIR. Suitable for applications such as environmental measurement, color measurement, quality control in production lines, and information devices.



    Our Raman spectroscopic modules include all the essential components needed to perform Raman measurements, such as excitation laser diode, polychromatic dispersion device, and optical and control circuit systems.


    FTIR Engine

    The Fourier transform infrared spectrometer (FTIR) engine is compact enough to carry in just one hand. A Michelson optical interferometer and control circuit are built into a palm-sized enclosure. Spectrum and absorbance can be measured by connecting a PC via USB. The FTIR engine will assist in creating portable handheld FTIR spectrophotometers for analytical applications including real-time monitoring of chemicals on production lines and ingredient analysis of agricultural products in the field.



    Ultra-compact sensors that house an InGaAs PIN photodiode and a Fabry-Perot Interferometer (MEMS-FPI) tunable filter that can vary its transmission wavelength depending on the applied voltage.
