New York-based Marktech Optoelectronics introduces silicon carbide (SiC) photodiodes designed for deep UVC detection. These photodiodes exhibit visible light or solar blind characteristics, which is ideal for monitoring 235nm and 255nm far or deep UVC LEDs.
Marktech’s new SiC photodiodes engineered for high sensitivity in accurately detecting deep UVC wavelengths. These photodiodes have a wavelength sensitivity range from 220nm to 358nm, making them ideal for applications requiring stringent monitoring and control of UVC light sources. Their visible light or solar blind properties ensure they are unaffected by ambient light, allowing precise UVC measurements without interference.
The new UVC detectors are available in two hermetic package types: the TO-46 metal can (part number MT12-001) and the ATLAS hermetic surface mount (SMD) package (part number MTSM1057SMF2-046). The hermetic characteristics of the TO-can and the proprietary ATLAS package protect the compound semiconductor photodiode chip from moisture, oxygen, gases, and other vapors, ensuring consistent performance over a long lifetime.
Key features and benefits of the new SiC photodiodes include solar blind characteristics, ensuring accurate detection of UVC light in diverse environmental conditions, and high sensitivity and precision due to the SiC material, enhancing the effectiveness of UVC monitoring systems. These photodiodes are suitable for a broad range of applications, including air and surface sterilization, water purification, and analytical instrumentation. Designed for long-term use, Marktech’s SiC photodiodes offer robust performance with high resistance to environmental degradation, ensuring durability and reliability.
“These new SiC photodiodes represent a significant advancement in UVC detection technology,” said Vince Forte, Chief Technology Officer at Marktech Optoelectronics. “Their ability to accurately detect 235nm and 255nm UVC wavelengths without interference from visible light positions them as a crucial component in any UVC monitoring system.”
