4D Technology Corporation (Tucson, AZ) has introduced its newly improved AccuFiz compact laser interferometer for accurate, repeatable measurement of surface shape and transmitted wavefront quality. New features include long- range wireless remote control, motorized tip-tilt and a variable sensitivity alignment system. The wireless remote provides control over instrument set- up, data acquisition and the motorized tip-tilt, for precise system adjustment without disturbing the cavity. The improved alignment system makes it easy to align weakly reflecting samples and high-loss cavities, even in high ambient lighting conditions. The new Surface Isolation Source option adds a second, external laser source to measure plane parallel optical surfaces, without the need for messy coatings or back-surface treatments to eliminate unwanted reflections.
