Optical filters (dichroic mirrors and band-pass) for use in a BD Biosciences 40 Parameter LSRFortessa Flow Cytometer Analysis Systems

The National Institutes of Health (NIH) /National Institutes of Allergy and Infectious Disease (NIAID) intend to award a contract on an Other than Full and Open Competition basis for Optical filters (dichroic mirrors and band-pass) for use in a BD Biosciences 40 Parameter LSRFortessa Flow Cytometer Analysis Systems with the following salient characteristics, 1). Modified Magnetron sputter deposition exposed surface-coated dielectric interference filters and beam splitters having highest transmission (typically 93-97% T) and highest signal-to-noise (S/N) ratio, for the near-UV (200 nm +) through N-IR (2000 nm). These products offer best durability and hardness. 2). Electron-beam (E-beam) deposition, lower-cost laminated or exposed surface-coated filters that allow for full edge-to-edge coverage of the filter surface. Durability meets MIL-PRF-13830B Moderate. Products include dielectric interference filters, exposed surface-coated dichroic mirrors and beam splitters, and anti-reflective (A/R) coatings. 3). E-beam ion-assisted deposition (IAD), E-beam deposition of reactive oxides for expanded capabilities in the ultraviolet (UV, 200 nm +) through N-IR wavelength ranges. Durability meets MIL-PRF-13830B Severe. Products include UV filters and coatings, exposed surface-coated metallic mirrors and beam splitters, and exposed surface-coated metallic induced-transmission filters, as well as an expanded material selection for dichroic beam splitters. 4). Resistive-source deposition, low-cost laminated and protected coatings for the visible (VIS) to near-infrared (N-IR) wavelength ranges. Products include dielectric interference filters, metallic induced-transmission filters, and metallic neutral-density filters. 5). Six years warranty covering filter efficiency and durability of standard reflection and transmission properties. The government will award a fixed price purchase order to the responsible contractor. The government reserves the right to make a decision whether this requirement is available for competition. All responsible sources may submit offers that will be considered by this agency. Offers must be submitted no later than 5:00 p.m. Eastern Daylight Time (EDT), May 15, 2015 to blandl@niaid.nih.gov.
