235 nm and 255 nm UVC LEDs for Sanitization, Sensing, and Medical Applications

Marktech Optoelectronics' cutting-edge UVC LEDs utilize Silanna UV chips and are designed to operate at peak wavelengths of 235 nm and 255 nm. These ultraviolet light emitters are integral to various applications requiring sterilization, sensing, and medical instrumentation. Their robust design ensures reliable performance in critical medical, pharma, analytical, sanitization, and biotech applications.

Unlike mercury vapor lamps, UVB LEDs, and UVA LEDs, radiation from 235 nm LEDs poses a minimal cancer risk. Deep ultraviolet (DUV) light, characterized by wavelengths shorter than 240 nanometers, cannot penetrate the skin's outermost stratum corneum layer. Consequently, this DUV light fails to reach or damage the living cells beneath the surface layer or further within the epidermis. In contrast, UVB radiation can reach the dermis, and UVA radiation can penetrate through the dermis to the subcutaneous layer beneath it. These features make Silanna Safe™ 235 nm UVC LEDs a more human-safe light source for sanitizers and sensors.

Engineered with meticulous attention to detail, these 235 nm and 255 nm ultraviolet germicidal irradiation (UVGI) LEDs offer a mercury-free and ozone-free sanitization solution for surfaces, water, and upper air, making them safer and environmentally friendly alternatives to traditional methods.

Precision-crafted 235 nm UVC LEDs are ideal for gas analysis, water quality, and medical diagnosis. These deep ultraviolet radiation sources can identify and quantify biomarkers such as creatine and urea in blood and other chemical compounds based on UV absorbance. With their slightly longer wavelength, the 255 nm shortwave UVC LEDs excel in water quality sensing, mercury vapor monitoring, upper air disinfection, and water purification. The 235 nm and 255 nm UVGI LEDs successfully eradicate viral and bacterial pathogens.

Marktech Optoelectronics' UVC LEDs are available in dome and flat lens package types, including its proprietary hermetic ATLAS SMD package, hermetically sealed metal cans (TO-39), and surface-mount devices (SMD) packaging. Shortwave UVC LEDs with multiple chips in a single package are available for higher power output applications.

Marktech's UVC LEDs offer inherent durability and longevity for excellent disinfection and sensing solutions. Incorporating these LEDs in medical and sensing devices advances the pursuit of health safety and analytical precision.
