Tender Details

Description

The National Institute of Standards and Technology (NIST) Acquisition Management Division intends to negotiate with Starna Cells, Inc., located in Atascadero, CA, on a sole source basis under the authority of FAR Subpart 13.106-1(b), soliciting from a single source, for SRM 2241a Glass Units.



Specific Requirements are as follows:



The Contractor shall deliver two hundred (200) glass substrates that meet the following minimum specifications:



Glass making specifications

The glass must have the following composition: The glass must be made at a high temperature of approximately but no lower than 1415 °C. The glass must be annealed to eliminate stress and strain as observed using polarized light Oxide weight %

SiO2 67.35

Na2O 6.95

B2O3 25.65

Cr2 O3 0.05

Cutting, polishing and finishing

Each glass unit must have Dimensions 10.0 mm +/- 0.1 mm by 10.0 mm +/- 0.1 mm by 1.65 mm +/- 0.05 mm. Each glass unit must have one of the 10 mm x 10 mm faces polished and the opposite face frosted. The polished face must be finished with a scratch-dig tolerance of 20-10. The polished face must be flat to 4 fringes at 633 nm. The frosted surface must be frosted to give 1 micron to 3-micron rms surface roughness (400 grit alumina sanding).Glass optical specifications

Measurement Conditions All emission specifications listed below must be evaluated using a Raman spectrometer system equipped with a continuous-wave 785 nm excitation laser. The system must be capable of measuring Raman/luminescence spectra down to at least 200 cm-1 from the excitation line with minimal background contribution ( Absolute Emission Intensity The absolute emission intensity values must match that of the original SRM 2241 units within 10% from 200 cm-1 to 3500 cm-1 Raman shift relative to 785 nm (797.5 nm to 1082.4 nm). Emission Spectrum The normalized emission spectrum of the glass units must match that of the original SRM 2241 units with...
