PRESS RELEASE

Digital Radius Slides

4D Technology, manufacturer of optical metrology systems, has introduced Digital Radius Slides for use with 4D AccuFiz compact laser interferometers. The Digital Radius Slides provide accurate axial positioning for measuring the radius of curvature of concave or convex optics.

Two Digital Radius Slide models are being offered: a linear encoder based version with 1µm axial resolution, and a high-accuracy laser-based option with 10nm axial resolution. Both versions are fully compatible with 4D Technology’s line of four and six inch optical mounting components.

4D has also added Radius of Curvature (ROC) analysis as a standard feature in its 4Sight data analysis software. The wizard-based software automatically reads axial positions from the Digital Radius Slide and provides rapid, accurate ROC measurement.
