2.Durango Commercial License provides you with a Hardware Key that enables Durango Interferometry Software to acquire data when installed on a computer that is properly interfaced to your interferometer’s camera and phase shifter.
3.Durango Annual Support and Upgrade Subscription entitles you to technical support and upgrades to Durango. A first year Support Subscription is included with each paid Durango Software License and optional in subsequent years.
