Marktech adds 230nm and 265nm deep UV, 310nm UVB and 340nm UVA LEDs
Marktech Optoelectronics Inc of Latham, NY, USA has announced an expanded portfolio of high-power UV LED light sources with new UV emitters spanning 230nm to 400nm. These devices strengthen the firm’s offerings across the ultraviolet light spectrum — from deep-UV LED (DUV LED, far-UVC LED) sterilization wavelengths to longer UVB and UVA wavelengths for curing, phototherapy and forensics.
The next-generation emitters meet the growing demand for UV sanitizing light, germicidal UV light (UVGI light), UV curing light, LED light curing, deep UV sterilization, phototherapy (psoriasis, eczema, vitiligo and acne treatment), PUVA therapy (enhanced UVA phototherapy using psoralens light-sensitizing compound), fluorescence excitation, spectroscopy, 3D-printing resins, water quality monitoring, medical UV light, UV water disinfection, and precision sensing applications.
The updated UV product family adds new deep UV (230nm and 265nm), UVB (310nm) and UVA (340nm) parts while maintaining reliability and precision. The range of wavelengths in the expanded UV LED lineup now includes: 405nm (near UV), 400nm, 395nm, 385nm, 375nm, 370nm, 365nm, 355nm, 340nm, 325nm, 310nm, 295nm, 285nm, 275nm, 265nm, 235nm, and 255nm.
Each device is engineered for high output and narrow spectral bandwidths. Custom multi-chip configurations, matched emitter-detector pairs, and starboard versions are available.
The updated product family includes UV LED chips or UV LED dies in a variety of packages:
- metal-can UV LEDs (UVC LEDs, UVB LEDs, high-power UVA LEDs);
- SMD UV LEDs, including the proprietary hermetic ATLAS SMD package;
- chip-on-board (COB) UV LEDs;
- 5mm and 3mm molded through-hole UVA LEDs (>350nm);
- compact, low-profile transfer-molded UVA LEDs (>350nm), coming in 2026.
All wavelengths are available off-the-shelf in all package types, but custom packages can be developed to meet OEM design needs.
