All of our devices are built, calibrated, and tested using industry leading tooling and test equipment. Our Hoffman Engineering ANV-126A coupled with the HVS Vision System allows us to calibrate devices with the utmost precision. Further, we are able to test and evaluate device parameters beyond human capability, ensuring absolute precision in calibration. Proper wrenches, drivers, spanners, and other specialized tools are required by the DOD to ensure proper assembly, while not damaging sensitive components. In addition to the proper specialized tooling and test equipment, we also utilize a controlled closed environment positive pressure air filtration system, laminar flow benches, and routine cleaning procedures in our clean build room. This allows us to maintain as clean an atmosphere as possible for device assembly and maintenance.
