About this file
This document is a Statement of Work (SOW) for a federal contract opportunity. The Observational Cosmology Lab at NASA's Goddard Space Flight Center requires custom lowpass and highpass filters for a cryogenic detector testbed. The vendor will provide 3 lowpass, 3 highpass, and 1 lowpass blocking filter, all 50 mm in diameter with a custom hole pattern. The filters must operate at cryogenic temperatures below 1 K, have greater than 90% transmission in the passband, and reject over 99% of out-of-band power. The work is to be completed by January 1, 2025 and will be performed at the Goddard Space Flight Center in Greenbelt, Maryland. The related federal contract opportunity is a Special Notice with Solicitation Number 80NSSC879940Q, seeking responses to the attached SOW and capability statement. Pricing should not be included in responses, and all correspondence should reference the Notice ID.

STATEMENT OF WORK
1. Objective/Requirements
The Observational Cosmology Lab at GSFC develops technologies and instruments for astrophysics and cosmology at far-infrared, sub-millimeter, and microwave wavelengths, including ultrasensitive, low-temperature, superconducting detectors. Cryogenic test facilities with the ability to illuminate detectors with known amounts of radiation across a controlled optical bandwidth are required for validation of detector designs and verification that detector performance meets mission requirements. The filters being procured are critical for defining the optical passband of cryogenic testbeds.
2. Characteristics, Scope, and Specs
The vendor will provide 3 lowpass and 3 highpass filters with edges near 3 and 6 THz, as well as a single lowpass blocking filter with a cutoff frequency at 10 THz. These filters will be 50 mm in diameter with a custom hole pattern for mounting. The filters must be demonstrated at cryogenic temperatures to < 1 K. The filters shall have transmission greater than 90% in the passband and reject > 99% of integrated out-of-band power.
3. Place of Performance
The filters will be housed in a cryogenic detector testbed at Goddard Space Flight Center.
4. Period of Performance
The work is complete when all filters are delivered and no later than 1/1/2025.
