Attachment 2_DF Below SAT - Part 12_Redacted.pdf

This is a Determination & Findings document for a single-source acquisition justifying a sole-source procurement action.

The contracting activity is AFLCMC/PZIBA, and the procurement is for a High Finesse WS8-2 wavemeter, a high-precision optical measurement instrument capable of measuring wavelengths to an absolute accuracy of less than 2 MHz. The wavemeter will be used for research to monitor exact wavelengths of light emitted by laboratory lasers and to develop next-generation optical technologies for the Department of Defense. The acquisition is justified under RFO 12.102(a) (Commercial Products and Services), citing that only one source is available. The document establishes that no other vendor has developed a wavemeter to the precision of Toptica's WS8-2, which can reliably measure wavelengths to less than 2 MHz accuracy, whereas competitors can only achieve down to 2 MHz precision. Toptica was confirmed on October 22, 2026, as the only authorized distributor for High Finesse wavemeter products in North America. Market research identified no other companies producing wavemeters meeting the less than 2 MHz requirement, though one potential future source shows theoretical capability but has not yet developed a product of this accuracy. The Contracting Officer, PZIBA, is the approval authority for this determination under DAF Approval Authorities Matrix PM 26-C-11 Matrix Item 51 for RFO 13.101(b) actions and GSAR 538.7104-3(a) for FSS orders.
