UV-LEDs Bring Standardized UV Dose Measurement

AquiSense Technologies launches low-cost, small footprint, UV-LED Collimated Beam Device

Collimated Beam Devices are an increasingly critical tool in providing a standardized unit of measurement for UV exposure.  Historically these devices have been expensive, cumbersome, and difficult to operate.  PearlBeam™ from AquiSense Technologies is a compact Collimated Beam Device which employs UV-LEDs emitting radiation in the germicidal range. Its small size and ease of use allows the realization of a table-top homogenized UV delivery system, which can be operated virtually anywhere in laboratory or even field locations.  Unlike mercury-lamp systems, the PearlBeam features a narrow band emission and is available in a suite of individually selectable wavelengths.

 “PearlBeam represents a significant upgrade from the old, bulky mercury-lamp units.  Because PearlBeam uses the latest UV-LEDs, it has a much smaller footprint, costs much less, and it very easy to use. It’s the best solution available,” says Chief Technical Officer, Dr. Jennifer Pagan. 

There are six standard configurations available, with single, double or triple wavelengths ranging from 255nm to 365nm.  They can also be fully customized to fit a specific need.

Each unit provides uniform and stable irradiation, thanks to a proprietary integrated heat management system. The temperature of each UV-LED is controlled with active feedback, preventing instant decay after turning on, which is typical of commercial 
UV-LED sources.  With UV-LED lifetimes up to 10,000 hours of constant wave operation, the PearlBeam requires no consumables.

Pricing for single wavelength units start below $2,000, and monthly rental options are 
available for users who have only have short term needs.

The PearlBeam is the first of several new standard products that will be launched by AquiSense Technologies in the coming months.
