Hamamatsu Photonics is excited to be exhibiting at WWEM and AQE this September. As the global leader in photonics technology, Hamamatsu is committed to advancing environmental sustainability through light.
Founded in 1953, Hamamatsu Photonics has spent decades pioneering optical technologies that power scientific discovery, industrial innovation, and meaningful environmental change. The technologies are designed to contribute to a sustainable global environment where the Earth, people, and all life coexist in harmony.
Clean water and air are essential for life, making the monitoring of their quality critical for human health, environmental conservation, and regulatory compliance. Hamamatsu’s optical sensors and light sources are used globally in assessing key water quality indicators such as nitrogen compounds, total organic carbon (TOC), chemical oxygen demand (COD), and chlorophyll a. Additionally, their cutting-edge optical technologies enable high-precision gas analysis through optical absorption using infrared (IR) or ultraviolet (UV) light, helping to detect environmental gases that pose significant risks to health and safety. These solutions are increasingly chosen for their sensitivity, selectivity, and compatibility with compact, field-deployable systems.
At WWEM and AQE, Hamamatsu will be showcasing a range of cutting-edge solutions including advanced optical components and systems that support environmental monitoring and analysis.
The S12742-254 Si photodiode is a high-precision UV sensor specifically designed for monochromatic light detection at 254 nm. With an ultra-narrow spectral response width of just 10 nm (FWHM), it delivers highly accurate photometric measurements with minimal stray light interference making it ideal for UV-based water monitoring systems.
In addition, the C16767MA micro-spectrometer is a compact, fingertip-sized device (20.1 × 12.5 × 10.1 mm) offering UV sensitivity from 190 to 440 nm. Equipped with a UV-hardened CMOS sensor, integrated stray light suppression, and advanced nano-imprinted concave grating, it enables real-time absorption spectrophotometry in both water and gas applications. Whether you’re developing portable water analysers for nitrites or compact gas monitors for ozone and NOx, these sensors provide powerful, scalable solutions.
For extended spectral coverage, Hamamatsu’s InAsSb and InGaAs detectors offer high sensitivity in the mid- and near-infrared ranges, enabling the detection of gases with absorption bands beyond the UV spectrum, including CO, CO₂, and hydrocarbons. This combination of advanced light sources and infrared detection expands the precision of gas monitoring systems in even the most challenging environments.
On display will be the world’s smallest excimer lamp, the EX-PEN. The lightweight, mercury-free excimer lamp is designed for seamless integration into environmental monitoring equipment, supporting miniaturization without compromising on power or reliability. Its eco-friendly design and high performance make it a standout solution for applications requiring UV light sources, such as sterilization and advanced oxidation processes. Also, Xenon flash lamps, which provide stable, high-intensity light pulses ideal for ultraviolet light absorption measurement and fluorescence excitation, can be paired with our compact, high-sensitivity photodetectors. These systems provide dependable, real-time gas sensing for environmental, industrial, and research use.
Whether you’re developing next-generation analytical instruments or seeking reliable components for regulatory compliance, Hamamatsu provides the expertise and technologies for applications from water monitoring to gas analysis, empowering researchers, engineers, and academics with the tools they need to make informed decisions.
