Endoscopic (laser) imaging is commonly used for applications with limited optical access in gas turbines, IC-engines and industrial furnaces. LaVision provides a variety of endoscopes for visible and UV light applications, such as PIV, LIF and high speed flame visualization. Cameras endoscopes are available for all types of cameras and intensified cameras. Illumination endoscopes are available for lasers and other light sources.

Endoscopic imaging solutions or upgrades can be provided for practically any (laser) imaging system. As part of the solutions LaVision offers pressure sealing inserts as well as customized mounting and installations.
