Photodiodes and Arrays

Excelitas utilizes Silicon and InGaAs materials for our photodiodes to provide detection from 220 nm to 1700 nm. These devices are offered in a variety of sizes to meet customer sensitivity and speed requirements.  Many different types of photodiodes are available to serve various unique applications.

Our photodiode arrays are used to generate an X-ray image by scanning an object line by line. The X-rays are converted into light through the attached scintillator crystal. The light intensity is then measured by the photodiodes. The boards are employing chip-on-board technology with optically-adapted scintillator crystals.
