Introduction to Photon Counters and Detectors
Photon counters are cutting-edge devices designed to detect and measure individual photons, the fundamental particles of light. These instruments are essential in applications requiring extreme sensitivity and precision, making them invaluable in fields such as quantum computing, medical imaging, spectroscopy, and environmental monitoring.
Photon counters operate by capturing single photons and converting them into electrical signals, enabling the detection of light at incredibly low intensities. This technology allows scientists and engineers to explore and analyze phenomena that are invisible to conventional light detection methods.
Typical applications of photon detectors
Typical applications include devices for detecting and measuring materials such as environmental toxins, proteins, particles in emulsions and solutions, as well as in research and development of modern drugs, cancer studies, genetic research, and clinical laboratory diagnostics. Additionally, SPCM modules are useful in super-resolution microscopy, fluorescence studies, particle sizing, 3D LiDAR photon imaging, and nanotechnology.
