Marktech Optoelectronics Launches Advanced 235nm and 255nm UVC LEDs: The Future of Germicidal UV Solutions

Dec. 4, 2023

November 14, 2023 - Marktech Optoelectronics, a leader in innovative light emission and detection solutions, proudly announces the release of cutting-edge 235nm and 255nm UVC LEDs from Silanna housed in flat and dome lens SMD and TO-cans packages (e.g., MTE2350F-UV and MTE2350D-UV). This release heralds a new era in germicidal UV applications, offering superior benefits over traditional UV lamps. The Silanna Safe™ 235nm emitting chips inside these UVC LEDs provide outstanding power efficiency without the skin cancer risks associated with higher wavelength UVC LEDs.

Designed for diverse applications, these UVC LEDs are set to revolutionize germicidal UV solutions and chemical sensing. Marktech can also provide the new 235nm and 255nm LEDs in custom packaging. In 2024, we will be releasing these groundbreaking UVC LED chips in a variety of packages including our award-winning hermetic metal-ceramic ATLAS package.

Applications include:

  1. Germicidal UV Solutions: Efficiently serving water purification, air disinfection, and surface sanitization needs.
  2. Chemical and Material Sensing: Enhancing UV-vis spectroscopy, nitrate sensors, ozone monitors, gas analyzers, and HPLC instruments.

A standout feature of Marktech's UVC LEDs is their safety profile. Unlike UVB and UVA LEDs, unintentional overexposure to Marktech 235nm UVC results in only short-term redness and eye irritation, eliminating the risk of skin cancer and cataracts.

Key Advantages of Marktech's UVC LEDs

  1. Compact and Efficient: With superior size, weight, power, and cost (SWaP-C) characteristics, these UVC LEDs are lightweight and consume minimal power. This compactness is especially beneficial for portable and transport applications, including water purification in boats, caravans, RVs, and remote systems for forest firefighters and military personnel.
  2. Exceptional Durability: These LEDs outlast conventional UV lamps with lifetimes expected to exceed 9,000hrs for 235nm LEDs and 18,000hrs for 255nm LEDs.
  3. No Infrared or Convection Heat Emission: Essential for disinfecting heat-sensitive materials, wounds, and infections without causing damage.
  4. Instantaneous Operation: The LEDs feature an instant start-up and can pulse on/off rapidly, eliminating the warm-up periods associated with mercury vapor UV lamps.
  5. Eco-friendly Design: These LEDs are a green solution, devoid of mercury, and do not produce ozone.
  6. Safety First: Operating at lower voltages ensures safer usage than traditional mercury vapor lamps. The Silanna Safe™ 235nm LED has minimal impact on human skin and eye tissue.

"Marktech's commitment to advancing UV lighting technology is evident in these 235nm and 255nm UVC LEDs from Silianna. We're not just offering a product; we're offering a safer, more efficient, and environmentally friendly solution for many applications," stated Vince Forte, Chief Technology Officer (CTO) at Marktech Optoelectronics.

Marktech encourages design engineers to develop products for water purification, air disinfection, gas sensing, and chemical analysis to explore the unmatched benefits of these revolutionary UVC LEDs.
