Technical Specifications:

Qualifire is available with either a 4-inch aperture or a smallest-in-class 6-inch aperture. Some Qualifire versions weigh less than 50 pounds (23 kg) making this instrument much easier to move—which is especially helpful when the test part cannot be brought to the instrument.

Another weight and spacing advantage is an internal Phase Measuring Receptacle (PMR). This eliminates potential damage to the PZT stacks inside the PMR when the unit is moved. Other improvements include easy-grasp handles and a convenient, easy-to-access On/Off switch.

In addition, the optical leg is sealed, providing additional protection for dust that accumulates over time and can add to artifacts in the system. This layout also makes service easier. Even the laser can be changed without disturbing any of the optical components.
