For multielement optical lens assembly, Opto-Alignment Technology has introduced CalcuLens 2.1.0, optical centration measurement software that calculates real-time total indicated runout, with high-speed automatic centroid capture, eliminating user error and improving uniformity and repeatability. It performs noncontact and instant submicron measurements for any lens surface, including cylindrical and parabolic, and coated or uncoated optics. It accommodates radius of curvature from ±2 mm to infinity. The user can perform inspection and quality control of centrations and wedges, import Zemax files, generate and save quality assurance reports for traceability, share files over the local network and receive live technical support via the Virtual Network. Features include tolerance zone recognition for repeatable productivity and unit conversion between English, metric and ISO/DIN.
