Ultra Narrow Beam UV LEDs for High Intensity and Collimation Applications

Ultra Narrow Beam UV LEDs for High Intensity and Collimation Applications

Violumas, provider of high-power UV LED solutions and inventor of 3-PAD LED technology, has launched an ultra narrow beam UV LED product suitable for collimation, focused illumination, long distance, and fiber coupling applications. With an integrated 10° fused silica optic, the VioBeam-1X1 achieves high intensities at extended distances, allowing for the reduction of LEDs in high-dosage systems. The LED is available in 255nm, 265nm, 275nm, 295nm, and 310nm wavelengths and ready for direct integration.

Violumas aims to provide the best variety of high-performance UVA, UVB, and UVC LEDs, encapsulated with the highest quality fused silica optics. The wide selection of beam angles (30°, 60°, 90°, 120°, and 135°) allows Violumas to provide unique solutions specifically tailored to any UV LED application. The newest addition to the product line, the VioBeam-1X1 series, offers an unprecedented ultra narrow 10° beam combined with a high-power UV LED, opening opportunities for new developments in ultraviolet applications.

The VioBeam-1X1 series is available in 255nm, 265nm, 275nm, 295nm, and 310nm wavelengths and delivers up to 0.1W optical output. The integrated 10° optic maximizes UV light in a small target area and is ideal for long-distance transmission with high intensity requirements. Compared to a typical 135° flat window, the VioBeam-1X1 can emit up to 55x higher intensity in a small spot size of 10x10mm at 50mm distance, thereby achieving high dosage targets with less LEDs.

With 5 UVB/UVC wavelength options, the LED’s impressive far-field intensity and focused spot illumination can be utilized for applications in life sciences, water disinfection, curing, spectroscopy, environmental monitoring, air purification, research, and more.

For fiber coupling applications, the VioBeam-1X1 can be coupled directly to an optical fiber or integrated with a secondary optic to achieve a collimated UV light source with minimal optical losses and costs. The VioBeam-1X1 can also be utilized as a standalone device for applications requiring high intensities at extended distances, such as water disinfection and air purification, which often require light to travel through long distances to meet minimum dosage requirements.

The powerful, integrated VioBeam-1X1 can be directly mounted into systems as a solder-free LED or provided with a heatsink as a compact, plug-and-play module. With the addition of the VioBeam-1X1 as a standard product, Violumas aims to provide a ready-made solution to high dosage applications such as disinfection, spectroscopy, and curing.  

This work was performed at University of British Columbia to develop a modular, energy-efficient, and spectrally tunable lighting system for photochemical experiments for simulating stratospheric, tropospheric and indoor light conditions.
