The Government intends to negotiate a sole source contract with:

Brimrose Corporation of America

19 Loveton Circle

Hunt Valley Loveton Center

Sparks, MD 21152

The Government has determined that no other source can meet this requirement. It is essential to have a high-performance visible-range free-space acousto-optic modulator that will satisfy the requirements of the trapped ion lab’s experiment. This system has been shown to work well for similar experiments. They are the only known source of the system described in above.  If these items are not purchased with these specifications, it will lead to a significant degradation in future experiments, yearly program milestones will not be met and a loss of two person years of work.

This is a notice of proposed contract action and not a request for competitive quotes; however, all responsible sources may submit a capability statement or quote, which shall be considered by the agency. All inquiries should be sent by email to jennifer.calandra-willson@us.af.mil.

Responses must be submitted by the date/time listed on the notice. Any response to this notice must show clear and convincing evidence that competition would be advantageous to the Government in future procurements.

Responses received will be evaluated; however a determination by the Government not to compete the proposed procurement based upon responses to this notice is solely within the discretion of the Government. The Government anticipates an award date on or before 15 September 2021.
