66 -- CCD CAMERA FOR HATACHI H-500H ELECTRON MICROSCOPE SOL RFQ2-36371(SLS) DUE 102595 POC Contact Sharon L. Sinnott, Telephone (15)604-6927, e-mail address to Sharon_Sinnott@qmgate.arc.nasa.gov NASA-Ames Research Center intends to procure a slow scan CCD camera and electron microscope interface which will attach to the second projector lens housing of an Hatachi H-500H Analytical Electron Microscope. The microscope interface is to include a removable beam stop for diffraction experiments. The image phosphor shall be at least 24 X 36mm. The shutter and aperture system for the camera is to be external to the microscope so that microscope conditions need not be changed during image collection. The camera system shall be compatible with an existing Apple Quadra 950 computer running IPLab Spectrum software. The data rate from the camera to the computer shall be no less than 1MHz. The camera system shall be of the cooled, low noise variety with a grade 1 CCD detector. It shall collect images which are at least 12 bits deep and at least 1500 X 1000 pixels in size, but images are to be binnable to provide for smaller image files and more rapid image collection. Pixel size of the camera shall be at least 9X 9 micrometers. At full resolution, images shall be collected in not more than 1.5 seconds. At less than full resolution, images are to be collected at at rate of several frames per second, such that real-time electron diffraction patterns can be collected in serial fashion. This solicitation is 100% set-aside for small business concerns. All responsible sources may submit a quotation which shall be considered by the Agency. All requests for copies of solicitation RFQ2-36371(SLS) should be in writing and directed to Sharon L. Sinnott. Telephone requests will not be accepted.
