Low-noise photodiode detectors for laboratories and industry
Fast and accurate measurement results for research and industry
Photodiode power detectors are the ideal solution for the precise measurement of low optical powers in the visible (VIS) and near-infrared (NIR) spectral range. Thanks to their high sensitivity and fast response time, they are ideal for applications in research, development, and industrial laser monitoring.
The strong wavelength dependence of photodiodes can be both an advantage and a limitation. Their spectral sensitivity acts as a natural filter, reducing noise from unwanted light sources, but different detectors may be required for different wavelengths.
Compared to thermopiles, photodiodes offer faster response times, lower noise, and greater immunity to temperature fluctuations. However, their high sensitivity also makes them more susceptible to ambient light interference, which often necessitates the use of optical bandpass filters to achieve reliable measurements.
Compact and efficient
With fast rise times of around 0.2 seconds, photodiode power detectors enable fast and precise signal responses. Depending on the model, they are optimized for different wavelengths in the range between 210 and 1650 nm and are particularly suitable for measuring low power levels. Variants with ND filters are also available on an optional basis, allowing the maximum compatible power to be increased slightly. Due to the sensitive electronics, you will achieve the best measurement results after a short warm-up phase.
