Available in multiple designs...
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 such as PEELS, post-column energy filters, STEM detectors or wide-angle cameras. The frame transfer CCD chip allows the FastScan-F114 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 pixel accurate assembly with compensation of intensity variations generate a large seamless image from a set of single exposures.						The video recorder option of EM-Menu 4 provides real-time (up to 27 fps) displaying of images and power spectra, and storing video sequences as movie or single frames, enabling high-end video microscopy for in situ applications.

			Fiber optical coupling						Optimized scintillators

			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, as a result, the sensitivity of the camera. The tapered fiber optics enlarges the field of view to 29 x 29 mm² and increases the resolution.						TVIPS optimizes the scintillator for individual demands. Resolution and sensitivity can be customized for high tensions up to 400 kV.

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

			Optional fiber optical coupling with a 2:1 tapered fiber optics (FastScan-F114T). The tapered fiber optics enlarges the field of view to 29 x 29 mm² and increases the resolution.
