1. This market research notice is being conducted by Network Contracting Office (NCO) 17 VHA Regional Procurement Office-West (RPOW) 124 E. Hwy 67 Suite 100 Duncanville Texas 75134 for the acquisition of Leica Stellaris 5 Confocal Microscope (Brand Name).

2. Background and Requirement: The requirement is a Leica Stellaris 5 digital confocal microscope equipped with an integrated white light laser (WLL), and Power HyD S silicon detectors. This system allows for the tuning of excitation between 485 nm and 695 nm with 1 nm precision, while imaging up to 8 laser lines during a scanning procedure with freely configurable detection up to 850 nm. The Power HyD detectors enable TauSense Technology, giving access to fluorescence lifetime-based information and intensity data simultaneously. The system also includes Lightening SR mode, an information extraction technology that provides near super resolution images in real-time. The microscope is also equipped with a Super-Z Galvo stage which affords fast, accurate Z-scanning and vibration free imaging. The Stellaris 5 will replace VA owned Lecia Confocal SP5, which is 10 years old. The new Stellaris will be a direct replacement using new (but similar) technology that will be able to perform live confocal imaging with the same or higher sensitivity and performance than the old Leica Confocal SP5.

3. These are the unique characteristics that are required and currently only the Leica Stellaris 5 Digital has the capability necessary to fulfill this need. The following features are required: a. The capability of the confocal microscope to utilize up to 8 spectral lines (between 485 nm and 695 nm with 1 nm precision) in a scan using white laser and acouto optical beam splitter (AOBS) and prism-based spectral detection technology. This is achieved without the use of dichroic filters. b. Capability of the system to dynamically separate autofluorescence emitted by a sample during the scan into a separate channel (tau sensing). c. Software that can be used to analyze any legacy data collected over the past decade on the users Leica SP5 confocal microscope system. d. Capability of the system to gather fluorescence data using pulsed laser-detector technology for the separation of signals from closely related fluorochromes.

4. The Leica Stellaris is the only confocal microscope system capable of meeting the above requirements. These advanced capabilities are not only required by studies to be conducted by the end-users, but proprietary to Leica Microsystems.

5. THIS NOTICE OF INTENT IS NOT A REQUEST FOR COMPETITIVE QUOTES. However, Contractors may submit a capability statement, proposal, or quotation which shall be considered by the contracting officer whether to continue with the sole source procurement or to solicit this requirement competitively. Responses received will be evaluated; however, a determination by the Government not to compete the proposed procurement based upon responses received to this notice is solely within the discretion of the Government. Only written responses will be considered. All responses from responsible sources will be fully considered. As a result of analyzing responses to this notice, the Government shall determine if a solicitation will be issued. 6. Any responses to this notice are requested by 3:00 PM Central Time on Tuesday, 28 June 2022.Send responses to Frank Mendoza at

DISCLAIMER: This notice complies with the requirements of FAR 5.201 and is issued solely for informational and planning purposes and does not constitute a solicitation. Responses to this notice are not offers and cannot be accepted by the Department of Veterans Affairs to form a binding contract. Respondents are solely responsible for all expenses associated with responding to this notice. End of Document
