Second Harmonic Generation Microscope

The Department of Commerce, National Institute of Standards and Technology (NIST), is seeking to procure a Second Harmonic Generation (SHG) Microscope under solicitation NB688000-26-01634, issued as a Combined Synopsis/Solicitation for Commercial Items under FAR Part 12. The requirement calls for a scanning confocal microscope configured with a pulsed laser source and second harmonic detector specifically designed to image electrically poled domains in thin-film lithium niobate on oxidized silicon wafers. The system must include high-sensitivity PMT detectors, pump light rejection filters, probe beam polarization control, a microscope objective of at least 50x (100x preferred), and a control PC or software. The laser source must feature a pulse width under 200 fs, a center wavelength near 800 nm with a 200 nm tuning range, and average power exceeding 1 W, with commercially accepted models such as the Coherent Chameleon Ti:Sapphire or Spectra Physics Mai Tai being referenced. All components may be supplied in used or refurbished condition, which is preferred. The procurement includes ancillary requirements such as on-site installation and start-up services, one year of full-service manufacturer warranty, delivery of microscope control software and electronic manuals, and on-site training for two personnel. Delivery must be completed within twelve weeks after receipt of the order, with FOB Destination terms applying to the NIST facility in Boulder, Colorado. The solicitation is evaluated under a Lowest Price Technically Acceptable (LPTA) methodology, where technical capability serves as a mandatory pass/fail gate. Offerors must demonstrate a clear and unambiguous understanding and ability to meet all minimum technical requirements with verifiable evidence in product literature or technical documentation; mere statements of compliance are insufficient. Proposals must be submitted electronically to Lisa Stevens at [email hidden] on company letterhead and structured in two separate portions: a firm-fixed-price quotation including all shipping and delivery costs, country of origin, and CLIN pricing, and a supporting technical section with detailed descriptions, drawings, and evidence of authorization from the original manufacturer if applicable. Quotations must remain valid for 90 days and include an affirmation that all solicitation terms are acceptable without modification. Offerors must have an active SAM registration with completed representations and certifications for NAICS code 334516, provide their Unique Entity Identifier, and submit required representations including those related to
