UVB Photodetector – TOCON_B4UVB+UVC
TOCON_B4UVB+UVC – Precision UVB Photodetector for Combined UVB and UVC Radiation Monitoring Applications
The TOCON_B4UVB+UVC from SGLUX GmbH is a precision-calibrated UVB photodetector engineered for combined UVB and UVC radiation measurement in sterilisation, environmental, and research applications.
It integrates a solar-blind Silicon Carbide (SiC) photodiode with a built-in low-noise transimpedance amplifier, providing a 0–5 V DC analog output directly proportional to irradiance.
With a spectral sensitivity range from 220 nm to 320 nm, and peak response near 290 nm, it accurately measures UVB and overlapping UVC wavelengths for process validation and lamp calibration.
Each unit is factory-calibrated and traceable to NIST / PTB standards, ensuring reproducible and traceable performance.
Compact, durable, and immune to visible and IR radiation, the TOCON_B4UVB+UVC is ideal for UV-curing systems, disinfection process monitoring, solar UV studies, and photobiological safety evaluations.
Understanding UVB Photodetector - TOCON_B4UVB+UVC
The TOCON_B4UVB+UVC uses a solar-blind SiC photodiode specifically designed to detect UVB and UVC radiation while rejecting visible and infrared light.
Operating between 220 nm and 320 nm, it delivers a stable, linear 0–5 V analog output through its internal low-noise amplifier, simplifying direct connection to monitoring systems or SGLUX SENSOR MONITOR 5.0.
Each sensor is factory-calibrated (NIST/PTB traceable), ensuring precision in UV disinfection validation, phototherapy calibration, and solar UVB studies.
The TOCON_B4UVB+UVC guarantees long-term stability, fast response, and high spectral selectivity, making it the benchmark detector for accurate UVB and UVC monitoring applications.
