In a sign of growing commercialisation of technologies using UV-C LEDs, a new compact collimated beam device for testing microbes has been introduced by AquiSense Technologies, a leader in the field of UV-C LEDs.

Collimated beam devices control delivery of light and can allow standardised exposure to UV light. Bacteria, viruses and spores each have a unique sensitivity to different UV wavelengths and exposure times. The PearlBeam device can be used to determine these sensitivities for different organisms.

The PearlBeam consists of a UVinaire LED module, a controller, and a collimating tube. It produces a testing area of 45.6 cm2 with homogeneous intensity distribution that is key for accurate dosimetry testing.

The benefits of the use of LEDs in this application include the fact that they do not require a warmup time, can endure an infinite number of on/off cycles, and reach full intensity in less than 10ns, according AquiSense.

Introduction of PearlBeam builds on the release by AquiSense Technologies of its PearlAqua system, the world’s first UV-C LED product designed for water disinfection.
