ZMI™ lasers provide frequency stabilized, two-frequency output to drive multiple measurement axes. The small ZMI™ 7705 is used with the ZMI™ 501A measurement enclosure to provide two axes of measurement. The larger lasers include features such as more power (7702), water cooling (7714), and separate laser source and delivery modules (7722/7724). These lasers can typically provide enough light to support tens of measurement axes.
