Galliumphosphide (GaP) Photodetector – TOCON_GAP7GAP
TOCON_GAP7GAP – Gallium Phosphide Photodetector for Accurate Blue and Near-UV Light Measurement and Calibration Applications
The TOCON_GAP7GAP from SGLUX GmbH is a factory-calibrated Gallium Phosphide (GaP) photodetector designed for accurate blue and near-UV light measurement in industrial and scientific applications.
It integrates a solar-blind GaP photodiode with a low-noise transimpedance amplifier, providing a linear 0–5 V DC output directly proportional to irradiance.
Sensitive in the 150 – 550 nm range with a peak response around 440 nm, the sensor is ideal for UV-A and blue-light sources while remaining completely blind to infrared radiation.
Each device is factory-calibrated and traceable to NIST / PTB standards, ensuring repeatable accuracy and long-term stability.
The TOCON_GAP7GAP is commonly used for LED testing, fluorescence analysis, optical instrument calibration, and process monitoring, offering robust performance for both laboratory and production environments.
Understanding Galliumphosphide (GaP) Photodetector - TOCON_GAP7GAP
The TOCON_GAP7GAP utilises a Gallium Phosphide (GaP) photodiode that offers selective sensitivity to blue and near-UV light while rejecting visible red and IR radiation.
This property ensures precise spectral measurement in the UV-A and blue regions, ideal for LED calibration, fluorescence monitoring, and photometric validation.
The built-in amplifier provides a ready-to-use 0–5 V output, simplifying integration with controllers and data loggers such as the SGLUX SENSOR MONITOR 5.0.
Calibrated to NIST / PTB standards, it delivers traceable and repeatable results for industrial, scientific, and optical applications requiring high spectral purity and measurement precision.
