GaP Blue Light Photodetector – TOCON_BLUE7
Precision Gallium Phosphide Sensor for Blue and Near-UV Light Detection in Optical and Industrial Applications
The TOCON_BLUE7 from SGLUX GmbH is a precision Gallium Phosphide (GaP) photodetector engineered for accurate detection of blue-visible and near-UV radiation.
It features a solar-blind GaP photodiode combined with a low-noise transimpedance amplifier, providing a stable 0–5 V DC output proportional to light intensity.
With a spectral range of 350 – 480 nm and peak sensitivity near 465 nm, it is ideal for blue-LED testing, fluorescence measurement, and optical calibration applications requiring high spectral purity.
Each sensor undergoes factory calibration traceable to NIST / PTB, ensuring reproducibility, long-term stability, and internationally recognised precision.
Compact, rugged, and ready for plug-and-play operation, the TOCON_BLUE7 is perfectly suited for laboratory, industrial, and field use where reliable blue-light measurement is essential.
Understanding GaP Blue Light Photodetector - TOCON_BLUE7
The TOCON_BLUE7 employs a GaP photodiode optimised for visible-blue wavelength detection and inherently immune to infrared and red light.
Its integrated transimpedance amplifier ensures a linear 0 – 5 V DC output, enabling direct connection to SGLUX SENSOR MONITOR 5.0, VOLTCON, or other data-acquisition systems.
With < 1 s response time, low signal noise, and high measurement stability, it delivers accurate and repeatable results even under continuous illumination.
Factory calibration traceable to NIST/PTB standards guarantees reliability for LED characterisation, photometric analysis, and industrial quality control applications.
