What types of photonic detectors do you offer?
Excelitas proudly offers a wide selection of gamma and x-ray machinery, among others, to support different applications across various industries. Our diverse portfolio of photonic equipment consists of the following product categories:  
  • Avalanche Photodiodes (APDs) are used for extreme low-level light detection and photon counting, providing excellent coverage within 400 nm to 1100 nm and 950 nm to 1550 nm for both Silicon (Si) and InGaAs, respectively.
  • Defense and Aerospace Photodiodes offered by Excelitas provide a wide range of photonic equipment designed to support a wide range of military and precision applications, including target acquisition, laser guidance, and warning systems.
  • Low-Light-Level Detection Modules (L3D) enable the detection of photons from 400nm to 1.7µm with industry-leading precision and performance.
  • Photodiodes and Arrays provide detection from 220 nm to 1700 nm offered in various sizes to meet customer specifications.
  • Phototransistors are designed to overcome unity gain, the major limitation among photodiodes, by integrating amplifiers and photodiodes inside a single chip for higher output.
What are the applications of photonic detectors?
Excelitas photonic detectors are designed and manufactured using the highest quality standards to create efficient products that suit a wide variety of applications. Here are a few:  
  • Avalanche Photodiodes (APDs): can be used in optical fiber receivers for communication, LiDAR and range finding, high-speed laser scanners, laser microscopy, imaging, and optical-time domain reflectometers.
  • Defense and Aerospace Photodiodes: military applications include detection systems, laser guidance systems, fire sensing and control, gyro systems for guidance, satellite positioning, position sensing, and nuclear radiation sensors.
  • Low-Light-Level Detection Modules (L3D): used to detect extremely low optical signals in specimens such as environmental toxins, proteins, emulsions, and particulate matter as well as drug, cancer, and genetic research and clinical diagnostics.
  • Photodiodes and Arrays: typically used in positioning sensing in shorter distances, optical coherence tomography, and the detection of gamma and x-ray machinery signals in industrial settings.
  • Phototransistors: used in settings where a higher responsivity rate is expected, which include security systems, encoders, IR detectors, circuitry in computer logic, punch-card readers, lightning control systems, and relays.
