Offerors must quote on all items to be eligible for award. The Government will award a contract resulting from this solicitation to the responsible offeror whose offer conforming to the solicitation.
BACKGROUND INFORMATION AND OBJECTIVE:
The National Eye Institute (NEI) is in the process of designing and implementing a next generation adaptive optics scanning light ophthalmoscope. A custom Avalanche Photodiode (APD) controller is needed to detect light used for retinal imaging in order to capture detailed images of cells in patients' eyes. An existing custom-built APD controller is currently being used in an existing adaptive optics scanning light ophthalmoscope. Additional detection channels that replicate the specifications of this existing custom-built controller are needed in order to expand and replicate existing imaging studies, which include longitudinal measurements. This custom APD controller satisfies these requirements and will be needed in order to allow NEI to carry out current and planned advanced retinal imaging studies.
APD devices are unlike most other detectors in that they are typically not "plug and play". This means that the procurement of an APD by itself is not very useful without having an electronics solution in place to amplify the signal and to control the temperature. The design of these electronics solutions is highly dependent on the application.

BASIS OF AWARD
Proposal must be exact, and substitution cannot be accepted.
A single module with a custom temperature controller incorporating an Excelitas C30659-900-R8AH APD is currently in use in the adaptive optics instrument in the NEI eye clinic. Additional modules are needed to extend experimental results and it is imperative that the exact same component be replicated. The physical dimensions of the new unit needs to fit within a 2U rack mount chassis and the APD component that is utilized must exactly match the specifications of the C30659-900-R8AH, which is a Si APD with spectral response from 400-1100 nm. The custom high voltage supply must be able to supply a voltage range of 0 to 425 Volts. A temperature controller (specified as Red Lion PXU41A20, 1 per channel) must be incorporated into the APD design as previously described for custom built adaptive optics scanning light ophthalmoscopes. Finally, the component must have been designed for an validated for use in a custom built adaptive optics scanning light ophthalmoscope. There is no other manufacturer that can provide a replica of the custom-designed circuit and detector that we need. We must use the Boston Micromachines solution which is only available directly from the manufacturer in order to avoid the introduction of new variables and to avoid long delays resulting from retesting of products from other potential suppliers. Data available is not adequate to assure that these parts, if procured from another manufacturer, will perform the same function in the equipment/system as the parts to be replaced. Further, drawings or specifications sufficient to obtain competition are not available.
