TemCam CMOS Camera (4k, 16µm, 16bit)
Introducing a new generation of TEM cameras, TVIPS launches TemCam-F416, the latest 16 MegaPixel camera, covering an image area of 64 x 64 mm². Custom designed CMOS architecture resulting in a large fill factor, high sensitivity and superior resolution combines the advantages of classical slow scan 4k CCD cameras with an exceptional acquisition speed. The CMOS sensor, showing absolutely no blooming or smearing on intensive illumination and the high quality 16 bit analog-to-digital converter, makes this camera an excellent choice for all types of applications requiring high dynamic range, such as acquisition of diffraction patterns.

			Large field of view						Rotatable

			Image area of 64 x 64 mm².						Depending on the specific flange, the camera can be freely rotated.

			Rolling Shutter Mode						Fast readout

			For even faster readout the sensor can be operated in the rolling shutter (RS) mode whereby no beam shutter is needed. Frame rates of up to 7.5 fps for a 1k x 1k subarea can be achieved. This mode is well suited for searching the object of interest.						Four readout ports, each sampling with 10 MPixel/sec, digitize the image information at full resolution within 1 sec. For a subarea of 4k x 1k, frame rates of 2.5 fps can be achieved.

			Fiber-optical coupling						Optimized scintillators

			Fiber-optical coupling of the electron-sensitive layer (scintillator) with the 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. For each high tension up to 400 kV, two standard types are available: optimized for high resolution (HR) or for high sensitivity (HS). On customer request individual scintillators can be manufactured.

			Near-axis flange

			TVIPS has designed a special flange which combines TemCam-F416 with FastScan-F114NX, a high-quality fiber-optically coupled CCD camera operating at video rate. Due to disadvantages of side-mounted cameras, the FastScan camera in the near axis position is an interesting option to monitor the TEM image and its power spectrum in real-time, for the main purpose of alignment or low dose search.
