- Description
- The Library of Congress intends to purchase through sole source from Hitech Instruments, Inc., 855 Sussex Boulevard, Broomall, PA 19008, a Carl Zeiss Discovery v8 Optical Stereoscopic Imaging System that will be used for examination, documentation and treatment of rare cultural, historical and artistic artifacts. This type of stereomicroscope imaging system is required to characterize the individual media and support of artifacts to clearly define the condition and material disposition of rare works and aid in conservation treatments. It is the Library?s understanding that the Carl Zeiss Discovery v8 Optical Stereoscopic Imaging System is the only one commercially available in the U.S. that is capable of meeting the Library?s critical performance requirement for an optical stereoscopic system that also meets the following requirements: The internal zoom lensing of the stereomicroscope must be apochromatically corrected, meaning that the lenses are perfectly color corrected for all wavelengths; the internal zoom lensing system must make it possible to integrate the multiple lens elements needed for an apochromat correction into a zoom stereo design; it must eliminate all color fringing seen at color boundaries that have been characteristic of stereo scopes so that the image is not occluded in that area; it must allow the quantification of color intensity, density and gradient without having inherent color errors in the optical system; it must have high transmission of UV light to detect and accurately document the autofluorescence from organic materials to characterize unknown materials or identify the presence or absence of a wide range of contaminants; it must have a Planapo 1X objective, with a measured numerical aperture of 0.022 to 0.116 with a depth of field of 1140 microns to 41 microns, and a Planapo 1.5X objective with a measured numerical aperture 0.033 to 0.174 with a depth of field of 510 microns to 18 microns; it must allow particles and structures to be detected and resolved at the 1-micron level; it must have constant resolving capabilities over the entire field of view with resolving capabilities at the edge of the image within 5% of the resolution at the center of the image; it must have an inherent design that eliminates 25-35% more stray light then any system without it to provide higher contrast images and reduce noise to an inconsequential level so that quantitation at lower light levels can be achieved; it must have a z-direction focus motor with a resolution of 35 nm to allow users to capture precise optical sections, use them to generate 3-dimensional data and images, and allow for precise and accurate height measurements of features less than 1 micron; it must include a fully integrated color CCD camera and frame grabber that is software controlled, with the camera sensor having an ICX282 interline transfer sensor with a pixel size of 3.4 microns by 3.4 microns with a 12-bit depth; the fully integrated color CCD camera must be peltier cooled to help reduce electronic noise when acquiring images, and the camera connection to the computer must be Firewire for fast data transfer; real-time subject viewing on the computer screen during analysis must be possible to enable easy targeting of sample micro-features, and the camera must utilize a format in saving images that allow the user to save critical data relating to the hardware used and various settings of the hardware so access to this data can be made for future reference; the camera software must be fully integrated and operable with a Windows XP computer and monitor; the instrument must be purchased from a local dealer convenient to the Library of Congress who can service the instrument on-site within 24 hours. Any other company that, at the time of application, (1) is either legally incorporated as a U.S. business entity or capable of demonstrating through its business plan its intention to be fully incorporated as a U.S. business, and (2) believes its Optical Stereoscopic Imaging System can meet all the above equipment performance requirements can apply to the Library for consideration. All responsible sources may submit a proposal which will be considered by the Library to Arneen Doizer via email at adoz@loc.gov. No phone call please.
