AquiSense Technologies has agreed to collaborate with International Light Technologies (ILT). Through the collaboration, the AquiSense PearlBeam™, a bench-scale UV device for research applications, will come with ILT sensors.
According to AquiSense, recent advancements in UV-C LEDs have resulted in the development of collimated beam devices that allow researchers to select multiple discrete UV-C wavelengths. The multiple UVC wavelengths give researchers greater precision that enhances their understanding of the response of microorganisms to UV light applications. More advanced sensors are required to track emission data as the precision of the wavelength emission increases. Under the terms of the agreement, ILT provides the required sensor technology with a handheld light meter.
“AquiSense recognized that an entirely new tool was required to advance UV science to take advantage of the many benefits of UV-C LEDs,” said AquiSense director of business development, Jim Cosman. “The PearlBeam was the first step in this process and now the incorporation of International Light Technologies advanced sensors is the next step in our quest to rapidly convert many disinfection applications from mercury-containing UV lamps to more environmentally sound UV-C LEDs.”
￼AquiSense points out that Collimated Beam Devices increasingly serve as a critical tool for providing a standardized unit of measurement for UV exposure. Historically these devices, which employ mercury lamps, have been difficult to operate, expensive, and cumbersome. AquiSense says that the PearlBeam is the world’s first UV-C LED collimating beam device that takes advantage of solid-state technology. This device, which can be used in the lab and the field, is small, light-weight, and does not contain fragile glass. Using UV-C LEDs enables instant on/off with immediate full intensity. The instant on/off enables exact exposure times. The LEDs also provide up to three UV-C wavelength options with an activation switch for each wavelength.
International Light Technologies boasts some of the most accurate light meters on the market. The sensor used with the PearlBeam will allow testing in the 255-300 nm wavelength range. This single sensor that can test in the 255-300 nm range prevents the need for several sensors to test a variety of wavelengths. ILT’s hand-held unit can provide data, trends, and averages in a portable setting making the combination of the PearlBeam and ILT sensors field-ready.
