FastScan-F114 represents a new generation of CCD cameras combining the superior quality of a slow scan CCD camera with the fast frame rate of a video camera. Various mechanical designs make it suitable to almost all TEMs, even when using various accessories, e.g., PEELS, post-column filters, STEM detectors or wide-angle cameras. The frame transfer CCD chip allows the FastScan to operate without beam shutter. Download product info (PDF, 3.2 MB)

			Tiling						Live image functions

			Tiling extends the field-of-view of your camera. Automatic acquisition and pixelaccurate assembly with compensation of intensity variations generate a large seamless image from a set of single exposures.						The FastScan-F114 Live Mode software not only provides basic features such as real-time flatfielding, histogram and power spectrum calculation, but also rolling average and a unique recorder for storing video sequences as movie or single frames enabling high-end video microscopy also in TEM.

			Fiber optical coupling						Optimized scintillators

			Fiber optical coupling of the electronsensitive layer (scintillator) with the CCD sensor increases the amount of light collected in comparison with lens-optical coupling and, as a result, the sensitivity of the camera.						TVIPS optimizes the scintillator for individual demands. Resolution and sensitivity can be customized for high tensions from 100 to 400 kV.

			Optional fiber optical coupling with a 2:1 tapered fiber optics (FastScan-F114T)

			Fiber optical coupling of the electron-sensitive layer (scintillator) with the CCD sensor increases the amount of light collected in comparison with lens-optical coupling and the sensitivity of the camera as a result. The tapered fiber optics enlarges the field of view to 29mm x 29mm and increases the resolution.
