Quantum Cascade Laser and Detector

The Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health (NIOSH), seeks quotations for a quantum cascade laser, infrared detection module, and thermocooler on a sole-source basis with Block Engineering LLC, with quotations due September 23, 2026 at 11:00 AM Eastern Time. The procurement carries no set-aside; however, NIOSH intends to award to Block Engineering LLC as the sole identified source meeting the Government's specialized requirements, though all responsible sources may submit competing quotations.

Place of performance is West Mifflin, Pennsylvania (626 Cochrans Mill Road, Pittsburgh). The equipment will support NIOSH research to develop a portable real-time monitor for respirable crystalline silica. Market research identified Block Engineering LLC as the only source currently known to provide a 12.5 micrometer wavelength tunable laser meeting the Government's required size, weight, and performance specifications necessary for incorporation into a portable field instrument.

The procurement requires one LaserTune-S package with Block QCL Tuner (wave numbers up to 970 cm⁻¹, full-range sweeps in 160 milliseconds, pulse durations 30–150 nanoseconds, repetition rates 100 kHz–1 MHz); one infrared detection module compatible with LaserTune-S, supporting 12.5 micrometer wavelength with spectral coverage extending to approximately 13.8 micrometers; and one VIGO Thermocooler Model PTCC-01-BAS. Peak power must be 375–625 milliwatts, average power stability less than 0.2 percent over one hour at 25 degrees Celsius, and pulse-to-pulse standard deviation less than 2 percent, verified through 100 percent inspection. Delivery is required within 120 calendar days after award, FOB Destination, firm-fixed-price basis with all freight included. Quotations must include pricing, manufacturer and model numbers, country of manufacture, product literature demonstrating technical compliance, delivery confirmation, warranty information, representations and certifications, and an AI Compliance and Risk Management Plan. Amendment 0001 (issued September 22) clarified infrared detector requirements and LaserTune-S compatibility specifications; quoters must acknowledge the amendment.
