Features & Benefits


​HALT: Highly 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 correction and improved design margins resulting in increased lifetime and reliability.

HASS: Highly Accelerated Stress Screening to Minimize Operational Failure

  • HASS testing reveals defects during product manufacturing.
  • HASS testing is more rigorous than normal operating conditions but well below HALT conditions.
  • HASS testing is most effective when included in the standard pro duction process

The History of HALT/HASS

In the 1970’s, HALT/HASS testing was originally applied to space-related projects including opto-mechanical and electrical systems. It’s now widely used in aerospace, automotive, medical, and consumer industries. Coherent uses an in-house HALT/HASS to test our industrial lasers as well as to design and build scientific lasers such as Vitara, Astrella, Revolution, and Chameleon.
