L3D modules are specialized modules or systems that are typically used in detecting and analyzing extremely weak light signals in low-light conditions. From single photons to mW, from 400nm to 1. 7µm, the Excelitas family of Low-Light-Level Detection (L3D) Modules offers industry-leading performance in compact, easy-to-use packages operating from a single 5V DC power supply. This SVDC power coherent receiver module integrates a high-speed, low-noise analog optoelectronic balanced detector and a high-quality fiber coupler. Our EL tester provides high-resolution imaging of solar cells, helping identify potential electrical issues that might affect module performance over. 4K Multi-Interface C-Mount CMOS Camera, supports HDMI2.
