E-MAIL: Glynda H. Meeks, glynda.meeks@msfc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Item 1: QTY 1 EA -- Vibration Insensitive Phase Shifting Interferometer per the statement of work/specifications below. Item 2: QTY 1 JOB -- Setup Interferometer Item 3: QTY 1 JOB -- Five days of on-site training at MSFC SPECIFICATIONS/STATEMENT OF WORK 1. Scope Since large telescope primary mirrors have radius of curvature greater than 10 meters, it is often impossible to make repeatable wavefront measurements using a commercial phase shifting interferometer without taking extreme measures in vibration isolation of the test setup. With advances in larger array and faster CCDs available today, it is possible to simultaneously capture and analyze four phase shifted interferograms using these and other optical components without taking extreme measures in the test setup. The primary mission for this interferometer will be testing lightweight mirror technology at cryogenic temperature inside a large vacuum test chamber at the Marshall Space Flight Center. The mirrors will be tested for its optical wavefront in ambient pressure, and temperature to ultra high vacuum and cryogenic temperature near 25 degrees Kelvin. The first set of mirrors will be spherical mirrors with diameter ranging from 0.6 to 2.0 meters, and radius of curvature of 15-20 meters. The second set of mirrors will be off-axis parabola with radius of curvature of 10 meters, and 1.2 to 1.5 meters in diameter. The interferometer will be stationed inside a 5.5 feet diameter guide tube with ambient temperature and pressure to allow operator manually adjusts the interferometer. A remote control unit and monitor separate from the interferometer mainframe in order to isolate thermal and vibration introduced by the operator during the measurement. 2. System overview The system shall consist of the following units: -- Interferometer enclosure -- Remote control unit -- Control computer, electronics, and monitors -- Software, operating manual and training 2.1 Interferometer enclosure The interferometer mainframe shall consist of an interferometer with the following features: -- > 400 x 400 spatial resolution of the 4 phase shifted interferograms simultaneously. -- Exposure time shall be set to very small value (faster than 1/3000 second.). Thus rapid fringe motions due to vibrations shall be essentially frozen and sufficient contrast maintained for a large range of vibrations. The exposure time or camera shutter speed shall be user defined. -- The optical components inside the mainframe shall be mounted robustly without much operator realignment. -- The mainframe shall be enclosed to prevent contamination to the optical components. -- The reflectivity of the reference mirror shall be optimized for best fringe contrast for coated and bare glass test surfaces. -- Using the remote control, a beam block shall be movable into the reference beam thus allowing to view the test beam only. This greatly facilitates the accurate definition of fiducials on the data maps. -- Frequency and intensity stabilized laser operating at 632.8nm to provide a long coherent beam. 2.2 Remote control unit The remote control unit shall be connected to the interferometer mainframe. The cable length between the remote control unit and the interferometer mainframe shall be at least 10 meters. 2.3 Control Computer with electronics The computer system shall be at least a Pentium-based system with 17" or larger SVGA-monitor (projected is a Pentium III at faster than 500MHz), running Windows 98 or NT. It shall also house the frame grabber board, as well as additional interface electronics to the interferometer. The internal hard disk drive shall be greater than 18 gigabyte capacity. The CD-Rom drive shall be a re-writeable CD-Rom version. It shall have a tape drive for archival purpose. 2.4 Software Software shall provide data analysis, data manipulation, and graphics features. Additional features shall include: -- data shall include wrapped and unwrapped phasemaps, 3D representation of phase -- real-time display of the 4 high-resolution video images -- user selectable data acquisition time intervals to allow operator to select the time between measurements, and number of measurements during the duration of optical measurements in days from ambient temperature and pressure to vacuum, cryogenic conditions and several cycles. -- average multiple phase maps -- difference phase maps -- fit and remove Zernikes 3.
