Gallium Phosphide (GaP) Photodetector – TOCON_GAP6
TOCON_GAP6GAP – Gallium Phosphide Photodetector for Precision Blue and Near-UV Light Detection and Calibration
The TOCON_GAP6GAP from SGLUX GmbH is a high-performance Gallium Phosphide (GaP) photodetector optimised for blue and near-ultraviolet (UV-A) light measurement in laboratory and industrial applications.
It integrates a GaP solar-blind photodiode with a low-noise transimpedance amplifier, producing a 0–5 V analog output proportional to irradiance.
With a spectral sensitivity range from 150 nm to 550 nm and peak response near 440 nm, it delivers outstanding accuracy for LED characterisation, optical calibration, fluorescence measurement, and curing-process monitoring.
Its infrared blindness ensures pure UV and blue-light detection without unwanted interference.
Each sensor is factory-calibrated and traceable to NIST / PTB standards, providing long-term stability, repeatability, and high signal-to-noise performance.
Compact, rugged, and maintenance-free, the TOCON_GAP6GAP is the preferred choice for precision blue-light and UV measurement systems.
Understanding Galliumphosphide (GaP) Photodetector - TOCON_GAP6GAP
The TOCON_GAP6GAP is a visible and near-UV photodetector that accurately measures radiation in the 150–550 nm range.
Its GaP photodiode provides high sensitivity in the blue/UV-A region and complete immunity to infrared and red wavelengths, ensuring unmatched spectral selectivity.
The integrated low-noise amplifier delivers a stable 0–5 V linear signal, simplifying connection with data loggers, PLCs, and SGLUX SENSOR MONITOR 5.0 systems.
Factory-calibrated to NIST / PTB standards, the TOCON_GAP6GAP ensures traceable precision and repeatability for optical calibration, LED testing, and fluorescence measurement, making it an essential sensor for blue and near-UV metrology.
