Marktech launches 235nm and 255nm UVC LEDs on starboards
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, and indium phosphide (InP) epiwafers — has launched its new 235nm and 255nm UVC LEDs mounted on starboards, an innovation designed to accelerate the development and prototyping of sensors, instruments, and sanitizers. The UVC LEDs on starboards relieve optical and electrical design engineers from the intricacies of PCB design and assembly, and allow them to swiftly evaluate the performance of 235nm or 255nm UVC LEDs in their projects.
The Silanna UVC LEDs are packaged in Marktech’s proprietary ATLAS hermetic SMD package, which provides environmental protection for UVC chips in a highly compact footprint. The new Silanna UVC LEDs on starboards are available in flat lens and dome lens versions. The flat lens provides a wider viewing angle of 120 degrees and the dome lens reduces the viewing angle to 60 degrees.

Advantages of Marktech’s UVC LEDs on starboards are listed as:
- Rapid prototyping: Engineers can skip the initial PCB design and assembly phases, speeding up the development cycle.
- High efficiency and safety: Featuring Silanna Safe 235nm-emitting chips, the UVC LEDs provide what is claimed to be outstanding power efficiency with reduced health risks. They ensure only minimal skin irritation without the long-term dangers of skin cancer and cataracts associated with higher-wavelength UVC LEDs.
- Durability and eco-friendliness: The UVC LEDs are designed for longevity, exceeding 9000 hours for 235nm and 18,000 hours for 255nm models, and are mercury-free, making them an environmentally responsible choice.
- Versatile applications: It is suitable for a diverse range of uses, from medical equipment to consumer appliances, promoting safer, more efficient sterilization, disinfection, and optical sensing.
“This launch marks a significant milestone in germicidal UV applications," claims Vince Forte chief technology officer. “By providing these advanced UVC LEDs on starboards, we are not only delivering a superior product but also empowering designers to bring safer, more efficient solutions to market quicker than ever.”
