 JEOL 1200EX STEM Click Picture for more info |
JEOL 1200EX STEM: A versatile analytical research instrument, this scanning/transmission electron microscope is able to operate in either transmission or scanning modes. The JEOL 1200EX has a magnification range of 600X to 500,000X and is capable of obtaining resolutions of 0.45 nm (in TEM mode) and 3.0 nm (in SEM mode). |
 TVIPS F224 Digital Camera |
TVIPS F224 Digital Camera The JEOL 1200EX is equipped with a high resolution digital camera, a Tietz Video and Image Processing Systems (TVIPS) model TemCam-F224. This is a bottom mounted slow scan CCD camera with a 2,048 x 2,048 pixel format. The CCD pixel size is 24 x 24 µm and the chip has a 49.2 x 49.2 mm recording area. These features enable image acquisition at very high resolution and extremely low beam intensity. This digital imaging capability enables the immediate observation and evaluation of labile, single use specimens such as frozen thin films. |
 ZEISS EM-900 TEM |
ZEISS EM-900 TEM: A basic transmission electron microscope that is easy to use and produces exceptionally high contrast images. The Zeiss EM-900 has a resolution of 0.5 nm and a magnification range of 150X to 250,000X. This microscope is equipped with a turbo-molecular pump system that produces an ultra-clean high vacuum and specimen observation condition. |
 ZEISS LSM 5 PASCAL Confocal Imaging System |
ZEISS LSM 5 PASCAL Confocal Imaging System The LSM 5 laser scanning module is a component of the Zeiss AxioPlan 2 light microscope and imaging system. This enhanced imaging capability provides true confocal or laser scanning technology for the examination of cells and tissues that are labeled with one or more fluorescent probes. Confocal imaging permits greater resolution of thick specimens and localization of organelles and gene expression labeled by very specific fluorescent probes. The Pascal is equipped with Ar (458, 488, & 514 nm excitation) and He/Ne (543 nm excitation) lasers. |
 LSM 5 PASCAL |
The scan module utilizes two independent galvo scanning mirrors to obtain large scan fields and high resolution images up to 2,048 x 2,048 pixels. This module also has two confocal channels and one transmitted light channel, all with highly sensitive photomultiplier detectors. All moving components of the scan module, such as emission filter wheels, main and secondary dichroic beam splitters, the pinhole and mechanical attenuators for each laser line, are computer controlled. Other features include flexible scan strategies for 3D and time series imaging, continuously adjustable pinhole for optimum Z resolution, precisely controllable laser intensities to protect specimens, and multifluorescence imaging without cross talk between channels. |

ZEISS AxioPlan 2 Imaging System: A research quality light microscope equipped for brightfield, phase contrast, Nomarski differential-interference contrast, and epifluorescence observation with UV, FITC, and Rhodamine filter sets. Image acquisition can be achieved with either an Olympus OM-4Ti SLR camera with 35 mm film or with the ZEISS AxioCam color digital camera with resolution levels up to 3900 x 3090 pixels. |
