The 2k x 2k Veleta fits perfectly into our product line of sophisticated, side-mounted TEM cameras, reflecting current requirements in Life and Medical Sciences, as well as in Materials Sciences.
Our very versatile VELETA (Model S04F) is a lens-optically coupled camera for the side-entry port of almost any TEM, covering with its 4 mega pixel CCD sensor an extremely wide range of applications. Having the strengths of speed and sensitivity as well as a high pixel resolution and a large field of view is provides the perfect balance of the main requirements of a modern TEM camera system for both Life and Materials Sciences at a very good price-performance ratio.
The large 27 x 27 mm² active area of the scintillator results in a field of view comparable to the size of a photo plate and makes the Veleta the perfect camera for e.g. pathology applications where fast overview images with high quality are needed. The CCD sensor’s smart architecture guarantees high anti-blooming, making it perfectly suitable for acquiring clearly distinguishable diffraction patterns.
As with all EMSIS side entry TEM cameras the VELETA exhibits the patented single-flange design for the wide-angle port of almost any TEM. Being mounted on either port, it can be freely combined with any other TEM equipment installed on the opposite side port (e.g. STEM detectors).
The modern sensor ensures more than five frames per second in full resolution and above 19 frames per second using binning, achieved by single port read-out only, not having the risk of possible synchronization problems of multi-port readouts. This high frame rate is ideal for locating suitable sample segments directly on-screen. In combination with the RADIUS Fourier features it offers ideal assistance for setting various microscope parameters.
No matter which imaging mode you select, our VELETA with its high versatility offers excellent dynamic range and high sensitivity resulting in always great images.
16 MEGAPIXEL SIDE-MOUNTED TEM CAMERA
The 16 megapixel TEM CCD camera MORADA G3 is the reinvention of the first commercially available high megapixel TEM CCD camera.
It offers the best value solution for all TEM image acquisition applications which require an extremely large field of view combined with highest resolution, high frame rates and excellent contrast.
The MORADA G3 provides up to 4872 x 3248 pixels, resulting in the largest field of view currently available for the side mount (35mm) port. The well adapted pixel size ensures best resolution and hence perfectly resolved images in low and mid range magnifications. The MORADA G3 camera system with its high precision, rigid, patented mechanics uses a custom made lens, ensuring minimum distortion and extremely high light transmission efficiency. The scintillators used, optimized for the respective high tension of the specific TEM, deliver a perfect signal–to–noise ratio, resulting in an outstanding image with optimal resolution and high sensitivity.
The smart and newly designed electronics of the MORADA G3 provide a large range of exposure times. Its low power consumption renders additional water cooling redundant.
This combination of advanced CCD technology and sophisticated electronics enables high speed performance. A fast viewing (high speed) mode allows the user to find specimen areas of interest quickly and efficiently, and to simultaneously zoom into interesting details without any delay. Thanks to these high frame rates, operations such as microscopy alignments and focusing are performed with high precision using the camera display instead of the TEM viewing screen. The MORADA G3 is a high speed digital imaging solution delivering outstanding quality and leaving absolutely no questions open for the demanding Life Sciences TEM user.
5.3 megapixel bottom-mounted TEM camera
Tengra is EMSIS’ 5.3 Megapixel TEM CCD bottom mounted on axis camera. This state of the art camera offers a great value solution for all standard TEM image acquisition applications with a strong focus on materials sciences. Tengra combines a large, sensitive CCD chip with attractively high readout speed, tapered ﬁber optics and a perfectly matched phosphor scintillator, to meet the highest quality demands.
The Tengra camera system provides extraordinary resolution with its 2:1 ﬁber optic taper, which increases the effective pixel size to 18 µm x 18 µm; hence ideally matching scintillator thickness and pixel size and ensuring that the maximum number of photons are detected. This highly efﬁcient conversion of primary electrons in the scintillator combined with optimized electronic design delivers a near perfect signal-to-noise ratio, resulting in an outstanding image with optimal resolution and high sensitivity.
A Peltier cooling, supported by a self contained water cooling system, minimizes the CCD dark current of the Tengra camera system and stabilizes the system temperature. A well capacity of over 60,000 electrons results in an efﬁcient 14-bit dynamic range and a perfect signal—to—noise ratio, ensuring data precision for any imaging task. The interline CCD chip provides up to 2304 x 2304 pixel resolution resulting in a large ﬁeld of view of 41 mm x 41 mm, which enables the camera to offer a ﬁeld of view corresponding approximately to half the size of a conventional photo plate.
The Tengra is a high speed digital imaging solution supporting several binning modes as well as partial read out. Using the binning mode increases frame rates and sensitivity. Capturing and streaming digital video directly from live images to observe dynamic events has been a basic element of our imaging platform already for years. The Tengra is an ideal solution for recording high resolution electron diffraction patterns. The high anti blooming performance of the CCD sensor and advanced CCD electronic design make the recording of electron diffraction patterns without artifacts an easy and routine task. It guarantees optimum sensitivity and resolution for diffraction imaging.
11 megapixel bottom-mounted TEM camera
The Quemesa provides everything expected of a high end TEM CCD camera today: the extremely high resolution, very high sensitivity, superior contrast, high frame rates, and a large ﬁeld of view. These superior properties make the Quemesa the ideal choice both for biomedical and materials science applications. The most satisfying aspect of this CCD TEM camera is that the TEM itself is now the only limiting factor with regard to resolution and sensitivity for most current TEM applications — no longer the camera.
High sensitivity and contrast at optimal resolution are the requisite ultimate goals for any TEM camera system. Every single photon generated in the scintillator per incident electron is of importance. The camera scintillator needs to be optimized to achieve the maximum signal from the pear shaped interaction volume. This is done by matching the effective pixel size through optimization of scintillator thickness. The Quemesa camera system does this perfectly. Bringing scintillator thickness and pixel size into ideal correlation with one another ensures the maximum number of photons is detected. This guarantees an outstanding image.
The 2:1 ﬁber optical taper provides the highest quality. This increases the effective pixel size to 18 µm x 18 µm. In combination with the optimized scintillator thickness, this ensures optimal resolution and sensitivity. The taper provides a further beneﬁt — an extremely large ﬁeld of view for a bottom mounted TEM CCD camera. Its dimensions are almost comparable to the photo plate size of most current TEMs.
The Quemesas fast single port read out supports high frame rates of more than 12 fps, making it much more convenient to scan and focus on the PC monitor. The use of single port readout ensures a homogeneous CCD response over the whole readout area. Even when in the highest quality mode (full resolution) the camera provides more than 2 fps. This camera provides superb dynamic range and sensitivity no matter which resolution mode is employed. Due to highly efﬁcient conversion of primary electrons in the scintillator and optimized electronics design, the Quemesa system gains a near perfect signal—to—noise ratio, resulting in very high sensitivity. This enables you to view your samples on your monitor at beam intensities so low it would normally prevent seeing an image on the TEM viewing screen. The ﬁnest detail is still shown perfectly in the camera image.
