VibroFlex QTec Fiber Optic Laser Doppler Vibrometer System

Background
The Air Force Research Laboratory's Structural Validation Branch (AFRL/RAVZ) at Wright-Patterson Air Force Base, Ohio, intends to award a single source purchase order to Polytec, Inc. for the VibroFlex QTec Fiber Optic Laser Doppler Vibrometer System.

This system is essential for measuring the dynamic response of structural components in thermoacoustic test facilities, supporting hypersonic research and flight test hardware qualification testing. The use of Polytec's proprietary QTec laser technology is critical for accurate, non-contact measurements under extreme conditions.

Work Details
The contract involves the procurement of a VibroFlex QTec Fiber Optics Laser Doppler Vibrometer System which includes:
- Ten (10) VibroFlex QTec single-point sensor heads equipped with fiber-optic lenses.
- Each sensor head will interface with a corresponding VibroFlex Connect Front End that serves as the system controller and data output module.
- The system will utilize Polytec MDE controlling software for configuration, data acquisition, and analysis, supporting up to eight (8) sensors concurrently.
- Deployment across facilities includes:
- Eight (8) sensor channels permanently integrated into the Large Thermoacoustic Test Facility.
- Two (2) sensor channels allocated to the Small Thermoacoustic Test Facility.

Period of Performance
Put the geographic location(s) the product will be delivered to or performed at here

Place of Performance
Wright-Patterson Air Force Base, Ohio

Bidder Requirements
Bidders must be authorized distributors or OEMs of Polytec products due to the proprietary nature of the technology required. The system must operate at a 1550 nm wavelength to avoid optical interference from existing equipment in the test cells.

Incumbent Analysis (see Incumbents section for more detail)
This opportunity appears to have a closely related prior contract with Polytec, Inc. (award 1333ND25PNB680420) for a differential laser Doppler vibrometer system valued at $96,583 (09/04/25–12/05/25). The current requirement for a VibroFlex QTec fiber optic laser Doppler vibrometer system is consistent with the prior work in that both involve laser Doppler vibrometry hardware and likely similar measurement functions, with the QTec fiber-optic configuration appearing as a continuation or upgrade within the same technology family.
