FAR Infrared Filter

The National Institute of Standards and Technology (NIST) is seeking specialized far-infrared optical filters for quantum microcalorimeter detector development through an unrestricted solicitation. The procurement involves four primary line items, including band filter sets for 25 mm and 90 mm configurations, a polarizer grid, and a filter set for operations below 650 GHz. This Request for Quotation (RFQ) is being conducted under Simplified Acquisition Procedures with a Lowest Price Technically Acceptable (LPTA) evaluation method, meaning NIST will identify the lowest technically acceptable quote. Potential vendors must submit quotations electronically to Lisa Stevens by March 28, 2025, and must have an active System for Award Management (SAM) registration. The technical requirements mandate high transmission within specified frequency bands, low out-of-band transmission, and the ability to operate in cryogenic environments between 0.1 and 4.0 Kelvin.

The solicitation is not set aside for any specific business category and falls under NAICS code 334413 for Semiconductor and Related Device Manufacturing with a small business size standard of 1,250 employees. The contract requires delivery within 16 weeks from order, with all items to be shipped F.O.B. Destination to NIST's location in Boulder, Colorado. Vendors must provide new equipment with no used, remanufactured, experimental, or prototype items accepted, and include a minimum one-year warranty. The procurement will cover multiple filter configurations, including bandpass, high pass edge, low pass edge, and infrared shaders, with clear apertures ranging from 70-100mm. Payment terms are Net 30 days and will be contingent upon installation, acceptance testing, and demonstration of performance according to technical specifications. The total contract value is not explicitly stated in the provided documentation.
