Marktech launches 235nm and 255nm UVC LEDs
Marktech Optoelectronics Inc of Latham, NY, USA, a designer and manufacturer of optoelectronics components and assemblies — including UV, visible, near-infrared (NIR) and short-wave infrared (SWIR) emitters, detectors, indium phosphide (InP) epiwafers and other compound semiconductors — has released 235nm and 255nm UVC LEDs made by Silanna UV of Brisbane, Australia, housed in flat and dome lens SMD and TO-can packages (e.g. MTE2350F-UV and MTE2350D-UV).

For germicidal UV applications, the Silanna Safe 235nm-emitting chips inside the UVC LEDs are said to provide outstanding power efficiency without the skin cancer risks associated with higher-wavelength UVC LEDs.
Designed for diverse germicidal UV and chemical sensing applications, Marktech can also provide the new 235nm and 255nm LEDs in custom packaging. In 2024, the firm will be releasing these UVC LED chips in a variety of packages including its hermetic metal-ceramic ATLAS package.
Applications include:
- Germicidal UV solutions: Efficiently serving water purification, air disinfection and surface sanitization needs.
- Chemical and material sensing: Enhancing UV-visible spectroscopy, nitrate sensors, ozone monitors, gas analyzers, and HPLC instruments.
Marktech says that a feature of their 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.
“Marktech’s commitment to advancing UV lighting technology is evident in these 235nm and 255nm UVC LEDs from Silanna,” says Marktech Optoelectronics’ chief technology officer Vince Forte. “We’re not just offering a product; we’re offering a safer, more efficient and environmentally friendly solution for many applications.”
