Luna Optoelectronics' Multi-Element Silicon Photodiodes consist of a number of photosensitive areas imaged on a single substrate, forming a one-dimensional array with a common cathode substrate. They feature low crosstalk among adjacent elements and high uniformity in response. These devices provide a cost effective alternative in applications requiring several photodiodes. In addition, optical filtering can be applied for tuning to particular wavelengths or, in the case of x-ray scanning applications, scintillation crystals that interact with the x-ray energy for provide imaging.
