Fast Scan CCD camera (2k, 14 µm, 14 bit, optional 2:1 taper)
FastScan-F214 is a 2k x 2k pixel, bottom mounted, on-axis camera with an image area of 28 x 28 mm². It is the perfect solution for demanding applications in materials science and life sciences. With its integrated mechanical shutter, the full frame CCD can be operated in a 2k x 1k pixel frame transfer mode to facilitate a frame rate of up to 8 fps. Using the optional 2:1 tapered fiber optics, FastScan-F214T offers an outstanding image area of 60 x 60 mm². A high quality 14 bit analog-to-digital converter makes this camera an excellent solution for all types of applications, requiring high dynamic range. Download product info (PDF, 2,5 MB)

			CCD cooling						Fiber optical coupling

			For optimum performance, the Peltier-cooled CCD chip (regulated at -10°C) is located in a vacuum housing separated from the microscope vacuum. The scintillator surface is kept close to room temperature. This design avoids contamination and allows venting the camera chamber without turning off the CCD camera.						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 60.2 x 60.2 mm² and increases the resolution.

			Optimized scintillators						Camera rotation

			TVIPS optimizes the scintillator for individual demands. Resolution and sensitivity can be customized for high tensions up to 400 kV. Two standard types are available: optimized for high resolution or for high sensitivity.						The camera can be freely rotated in order to align it to the specimen feature or the tilt axis of the goniometer.
