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.
