…Accelerated Lifetime Testing to Detect and Rectify Failure Modes
* HALT testing reveals failure modes during product design phase.
* HALT testing exceeds normal operating levels, including simultaneous fast temperature changes and 5-axis
* randomized vibration.
* HALT testing enables faster…
…Coherent rigorously tests every laser during the design and production phases to weed out design and manufacturing weaknesses, resulting in a new level of reliability for ultrafast lasers. During the design phase, we’ve adopted an industrial-grade HALT (Highly Accelerated Life Testing) protocol in…
…and QA Testing Not only can beam size, position and power data be continuously displayed in analog, digital and strip chart forms on the computer screen, but they can also be logged to a data file in real time for later processing or test report generation. Pass/Fail testing can be performed…
