    heliCamTM C3 - Fast Lock-In Camera

    The lock-in camera was originally developed for low coherence interferometry, but the heliSenseTMS3sensor and the camera board have found new life with a variety of applications other than OCT, for example, pump-probe spectroscopy. For ease of integration, the Heliotis' core technology is now available as a rigid camera, capable of capturing and processing more than 1 million 2D-images per second.
