UVA Photodetector – TOCON_A5UVA
TOCON_A5UVA – High-Sensitivity UVA Photodetector for Low-Intensity Radiation Measurement and Photobiological Applications
The TOCON_A5UVA from SGLUX GmbH is a high-sensitivity UVA photodetector designed for low-intensity ultraviolet radiation measurement across industrial, environmental, and scientific fields.
It integrates a solar-blind Silicon Carbide (SiC) photodiode with a precision low-noise transimpedance amplifier, offering a 0–5 V DC linear output proportional to irradiance.
Covering a spectral range of 320–400 nm and peaking around 350 nm, it ensures highly accurate measurement of weak UVA signals, ideal for photobiological research, exposure monitoring, and laboratory testing.
Each unit is factory-calibrated to NIST / PTB standards, ensuring international traceability and repeatable performance.
Compact, rugged, and resistant to visible and infrared interference, the TOCON_A5UVA guarantees stable and precise readings in controlled or outdoor environments requiring reliable UVA monitoring.
Understanding UVA Photodetector - TOCON_A5UVA
The TOCON_A5UVA is a solar-blind UVA photodetector specifically optimised for low-level UVA measurement from 320 nm to 400 nm, with maximum sensitivity near 350 nm.
It features an integrated transimpedance amplifier, delivering a stable 0–5 V DC signal that directly corresponds to the measured irradiance.
By rejecting all visible and IR light, the sensor ensures pure UVA detection under diverse lighting conditions.
Factory-calibrated to NIST/PTB standards, the TOCON_A5UVA provides traceable, precise readings for UVA safety assessment, photobiological exposure control, and optical research applications where accuracy and stability are essential.
