Hitachi 8100 Transmission Electron Microscope
Hitachi H-8100 TEM is a research grade scanning/transmission electron microscope (STEM) with analytical and high resolution imaging capabilities. Systematic theoretical instruction combined with practical hands-on training is the best way to thoroughly understand the utility and capabilities of this complex and delicate instrument. These instructions are meant only as a guide to the basic, daily alignments and operations of the H-8100, i.e. general imaging and diffraction. It is by no means a comprehensive guide to all operations of the microscope including ultra-high resolution imaging, SEM, EDX, cryo, and the various diffraction techniques. These advanced, specialized techniques will be dealt with on an as-need basis after mastery of the basic operations has been demonstrated. [Product Link]

Leica EM FC6 UC6b Ultramicrotome
Leica Ultracut EM UC6 is an advanced ultramicrotome that features a Touch Screen Control Panel or a Keypad Control Panel. Both options enable fast and safer alignment of knife and specimen, and the programmable knife and cutting movements make trimming easy. With Leica's AutoTrim, you can automatically trim a specimen to a predetermined level in the block face, best for morphometric studies. Three dependent, built-in, brightness- controlled LED light sources provide outstanding illumination for top light, back light, and specimen transillumination. [Product Link]

Leica TCS SP2 Confocal Laser Scanning Microscope
Leica TCS SP2 is a spectral confocal laser scanning microscope with 405 UV laser 3CHDIC digital emission 400-800nm range designed to acquire high spatial resolution images of fluorescently labeled materials and for analysis of these images. The confocal principle utilizes a pinhole (confocal aperture) to eliminate out-of-focus light from fluorescently labeled specimens (i.e., provide â€œoptical sectioningâ€?). Lasers provide intense, point illumination that is scanned over the preparation and the fluorescence at each point is quantified and used to construct a representation of the object brightness (an image). This method provides high resolution for the x and y planes as well as vertically (z plane). The SP2 is an advanced confocal system with nine laser excitation lines spanning the spectrum from UV to near IR. The following laser lines are available: 405nm, 458, 476, 488, 496, 514, 543, 594, and 633, all fiber coupled and controlled by AOTFs. [Product Link]

MAI also houses two electron microscopes. These include:
1. Hitachi H-8100 lanthanum hexaboride (LaB6) Transmission Electron Microscope (TEM) is housed in room 1043E of the MAI. The Hitachi H8100 LaB6 TEM is equipped with an assortment of single and
double tilt, single-specimen, beryllium room temperature holders and can operate at 75 kV, 100 kV, 150kV, 175 kV, and 200 kV (75 to 200 kV), making it possible to observe biological and non-biological materials of a wide range of thickness. The Hitachi H8100 LaB6 TEM is also equipped with a Advanced Microscopy Techniques (AMT) BioSprint high speed 16 megapixel (MP) low-mount CCD camera which provides high resolution digital capture of publication-quality images. The AMT BioSprint 16 MP low-mount CCD camera is controlled by a DELL Optiplex 7070, 64 bit mini tower workstation with Intel Core i7-9700 (8 Cores/12MB/8T/up to 4.7GHz/65W), 32GB 2x16GB DDR4 2666MHz UDIMM Non-ECC, AMD Radeon R5 430, 2GB, FH, 1TB Solid State SD Hard Disk Drive, 3.5" 1TB 7200rpm SATA Hard Disk Drive, Samsung 28-Inch UE570 UHD monitor, DVD-ROM Drive, and 8x DVD+/-RW 9.5mm Optical Disk Drive, running Windows 10 Professional 64bit. The Hitachi H8100 LaB6 TEM uses hollow-cone beam illumination, a beam illumination method by which a cone shaped electron beam is produced to perform diffraction. In hollow-cone beam illumination, the beam is tilted to a certain angle against the optical axis by the first-stage deflection coils and is tilted back by the second-stage deflection coils to illuminate the same position on the specimen, then, the beam is rotated
with respect to the optical axis keeping the same illumination position. Hollow-cone beam illumination is used to eliminate diffraction contrast in bright- and dark-field images and to observe the symmetries produced only by higher-order Laue zone (HOLZ) intensity bands without strong intensity due to zeroth-order Laue zone (ZOLZ) intensity band interaction in the convergent beam electron diffraction
(CBED) pattern, composed of non-overlapping disks (Kossel-Möllenstedt [K-M] pattern) for small
convergence angles and over-lapping disks (Kossel [K] pattern) for large convergence angles.
