66 -- CONFOCAL MICROSCOPE SYSTEM SOL 263-96-P(PO)-0028 DUE 092796 POC Mr. Greg Holliday, Contract Specialist, 6120 Executive Boulevard, EPS/803 Rockville, Maryland 20892. The Government intends to negotiate with Carl Zeiss, Inc. on a sole source basis under the authority of 41.U.S.C. 253(c) (1) for a Confocal Microscope System. The system shall have an adjustable confocal aperture for each fluorescens detector; Shall be equipped with 4 detectors (3 fluorescene and 1 transmitted) and shall be able to record from any three simultaneously. The system shall be able to simultaneously process three channel data. The system shall display true R,G,B, for any of the three channels, (up to 1024 x 1024 pixels per channel. The systems shall scan up to 512 x 512 in 500 msec and 1400 lines per second. The system shall include dual galvano scanning mirrors allowing for full rotation of the scan to a tenth of a degree through 360 degrees. The system shall have interpretive macro language with graphical user interface built into the LSM application software. The system shall provide for full range of focus of the axiovert (9.9 mm) in increments to 50 nm. The system shall include water immersion lenses designed for confocal. These lenses shall have long working distance, adjustable cover slip correction, high transmission in the near UV through IR wavelenghts, specifically, the 40X C-APO 1.2 NA with 220 micron working distance and adjustable cover slip correction from.14 to .18 mm. The lens shall provide depth of field of 1 rayleigh unit = um at 546 nm. The correction collar shall carry 2 divisions going beyond the minimal range from .13 to 19 mm. The lens shall offer correction for temperature of varied samples at either 23 or 37 degrees Celsius. It is the Government's belief that these requirements can be met by Carl Zeiss, Inc.. This is not a formal solicitation. However, concerns that respond to this notice must furnish concise responses directed specifically to the requirements mentioned above. Sources demonstrating the capability to accomplish the above shall supply pertinent information in sufficient detail to demonstrate that ability to perform. Information furnished shall include enough material to perform a proper evaluation. Respondents will not be notified of the evaluation results. Closing date will approximately 45 calendar days publication of this notice. See Numbered Note 22. (0191)
