Sensors & Detectors

Standard and custom photodetectors and high-quality VIS and IR LEDs. Our advanced performance sensors operate from the extreme ultraviolet (UV) to the mid-infrared (mid-IR). Photodetectors provide high-energy particle, electron, x-ray, and UV detection; plus excellent mid-IR sensitivity to discriminate gases, detect heat, sparks, and flames.
