Opto Alignment QuickPRO-CUBE™ Mini
The QuickPRO-CUBE™ Mini enables measurement of both sides of optical components, either polished or ground surfaces in order to measure back to front Wedge Angle, TTV, Centre Thickness, Vertex Offset and Sag/Form error.
By integrating a pair of single-point, non-contact, nanometer-resolution chromatic confocal sensors with high-speed, nanometer-encoded X/Y/Z co-ordinated motion, the Opto Alignment QuickPRO-CUBE™ captures simultaneous front, back and datum surface 3D point cloud topography for the geometric characterisation of single lenses or micro lenses in trays. The form invariant motion architecture permits measurement of both rotationally symmetric and more complex non-axially symmetric or freeform shapes to a maximum measurement diameter of 50mm (up to 75mm OD). For a lens, the total measurement time is from 30sec to 240sec per surface per lens, depending on the lens diameter and 3D point cloud sampling density.
Measured geometric parameters include:
- Front-to-Back surface Vertex Offset relative to defined centration datum
- Front-to-Back surface Wedge Angle relative to defined tilt datum
- Front-to-Back Total Thickness variation (TTV) and Centre Thickness (CT)
- Front and Back surface Sag/Form error
Applications
The CUBE is specifically designed for factory-floor QA of polished, moulded, or diamond turned optical components, including optically opaque infrared materials and metals. An added advantage is the ability to measure multiple smaller lenses in-tray or lens arrays during a single measurement sequence.
The CUBE is capable of measuring ground surfaces as well as polished, specularly reflective surfaces.
