66 -- RESEARCH GRADE SCANNING ELECTRON MICROSCOPE SOL N00173-00-R-AT01 POC Evangelina R. Toledo, Contract Specialist, Code 3220.AT, (202) 767-2021, Wayne Carrington, Contracting Officer E-MAIL: Click here, TOLEDO@CONTRACTS.NRL.NAVY.MIL. This modification is issued to answer technical questions regarding the combined synopsis/solicitation N00173-00-R-AT01 for Research Grade Scanning Electron Microscope that was issued on 04 February 2000. Question No. 1: Regarding item 10, should it read "The system shall have probe current adjustment" instead of "The system shall have prove current adjustment?" Answer: Item 10 should read "The system shall have probe current adjustment." Question No. 2: Regarding item 16 "The system shall have 5 axis motorized stage with touch alarm." There is no mention of, or specification for the amount of stage traverse or the chamber size. This would be critical in determining the size of the End-user's samples and how much of mentioned samples could be viewed (imaged). Answer: The specimen chamber shall be at least 300mm in length, 260mm in width or greater and 190mm deep, and shall contain accessory ports for the adaptation of other equipment should the need arise. In order to accommodate larger specimen sizes that are sometimes used, it is necessary to have a Z clearance greater than 70mm. The 5 axis motorized stage shall have a travel range as follows: 1) X= 100 mm or greater; 2) Y= 125 mm or greater; 3) Z>30mm; 4) Tilt 0-90 degrees; and 5) Rotation 360 degrees. This size is necessary to view the entire area of a 4 to 5" silicon wafer at high tilt angles. The Z clearance is necessary to view large objects, which sometimes arise when examining samples for end users. It is also desirable to have a multi-sample holder to speed examination. Offerors are advised to include with their offer a completed copy of the following provisions: FAR 52.212-3, Offeror Representations and Certifications-Commercial Items (Web site: http://heron.nrl.navy.mil/contracts/reps&certs.htm) and DFARS 252.225-7000, Buy American Act-Balance of Payments Program Certificate.
