Broadband UV Photodiode – SG01L-5Lens
Compact Large-Area UV Photodiode with Integrated Lens for Enhanced Sensitivity in Industrial and Scientific Applications
The SG01L-5Lens is a Silicon Carbide (SiC) broadband UV photodiode designed with a compact footprint, 0.03 mm² active area, and an integrated optical lens to enhance ultraviolet light collection. With a responsivity peak of 0.13 A/W at 280 nm and a responsivity range from 221–358 nm, it ensures precise UV-only detection with complete visible blindness. The lens design focuses incoming UV radiation onto the active area, boosting responsivity without increasing the physical size of the diode. Featuring an ultra-low dark current of 0.1 fA and capacitance of 7 pF, the SG01L-5Lens delivers low-noise, high signal-to-noise performance with fast response times. Operating from −55 °C to +170 °C, it is highly reliable in industrial, aerospace, and outdoor environments. Applications include flame detection, UV curing control, sterilisation monitoring, ozone studies, photonics research, and defence-grade UV sensing. The SG01L-5Lens combines compactness, durability, and enhanced responsivity for mission-critical ultraviolet detection.
Understanding Broadband UV Photodiode - SG01L-5Lens
The SG01L-5Lens broadband UV photodiode combines Silicon Carbide detection technology with a built-in optical lens for improved sensitivity.
