L3D modules are specialized modules or systems that are typically used in detecting and analyzing extremely weak light signals in low-light conditions. These modules often incorporate incredibly sensitive photodetectors, such as avalanche photodiodes (APDs) or photomultiplier tubes (PMTs), with supporting electronics and signal processing capabilities to enable the detection and measurement of light signals that are way below the threshold of human perception. These capabilities are best utilized in applications like astronomy, flow cytometry, particle characterization, quantum cryptography, wind LiDAR.
Excelitas incorporates only the best in cutting-edge technology in order to develop advanced photonic solutions that provide industry-leading performance and reliability. Our L3D modules are available in compact, easy-to-use packages, described as follows:
- Single Photon Counting Modules (SPCMs) - this family of self-contained modules meet the low-light-detection demands of applications in specialized fields like confocal microscopy, luminescence, fluorescence, time-related single photon counting (TCSPC), particle sizing and quantum communications. Products within this family include the SPCM-AQ4C, SPCM-AQRH and SPCM-AQRH-TR and SPCM-NIR.
- Coherent InGaAs PIN Balanced Receiver Module (CIPRM) - this series of balanced optical receivers offers a practical solution for the detection of small changes above the interfering noise floor of incoming optical signals, canceling out the common optical noise. It features high-performance InGaAs photodiodes and a low noise, high gain transimpedance amplifier.
L3D Modules offer significant benefits well-suited for a wide range of applications across industries that require sensitive light detection capabilities in the most challenging lighting conditions. These include the following applications:
- Quantum communication
- Particle sizing
- Confocal microscopy
- Photon correlation spectroscopy
- Quantum cryptography
