Broadband UV Photodiode – SG01M-5Lens
Metal-Packaged Compact UV Detector with Integrated Lens for Enhanced Sensitivity, Precision, and Reliable Industrial Applications
The SG01M-5Lens is a compact Silicon Carbide (SiC) UV photodiode in a rugged metal housing, equipped with an integrated optical lens for improved light collection and higher responsivity. With a peak sensitivity of 0.13 A/W at 280 nm and a detection range between 221–358 nm, it ensures accurate and selective ultraviolet detection with outstanding visible blindness. The integrated lens focuses incident UV radiation onto the 0.03 mm² active area, enhancing sensitivity without compromising compactness. Ultra-low dark current of 0.1 fA and a capacitance of 7 pF provide noise-free measurements and fast response, supporting high signal-to-noise performance. Designed to withstand temperatures from −55 °C to +170 °C, the SG01M-5Lens is ideal for harsh industrial, aerospace, and outdoor environments. Applications include flame detection, UV curing, solar monitoring, ozone research, sterilisation monitoring, and photonics development. Its robust design and optical enhancement make it a trusted solution for high-precision UV sensing.
Understanding Broadband UV Photodiode - SG01M-5Lens
The SG01M-5Lens combines Silicon Carbide (SiC) UV detection technology with a metal package and an integrated optical lens, delivering enhanced responsivity and precision. The lens concentrates UV light onto the photodiode’s 0.03 mm² active area, maximising sensitivity in compact applications. With a responsivity peak of 0.13 A/W at 280 nm, low dark current of 0.1 fA, and fast response enabled by 7 pF capacitance, it provides reliable performance even in weak UV conditions. Its rugged design and wide operating temperature range (−55 °C to +170 °C) make it well-suited for aerospace, industrial monitoring, flame detection, and long-term UV research.
