    Asphere Lens Contour Deterministic Microgrinding 101

    The most effective technique for small to medium scale production of aspherical optical components is contour Deterministic MicroGrinding (DMG). OptiPro Systems, located in Ontario NY, has been a leader in precision optics manufacturing technology since the early 90's. The OptiPro eSX series of DMG grinding platforms provides an affordable and deterministic manufacturing process for aspheric shapes. With its user friendly interface, flexibility, and minimal dedicated tools required, the eSX series provides a stable operation for a wide range of optical materials ranging from relatively soft glass to hard polycrystalline ceramics with significant microstructure. Here, we discuss the main steps and considerations for deterministic contour grinding of aspheric surfaces.


    Asphere Lens Sub-Aperture Polishing 101

    Sub-aperture polishing tools have been revolutionizing the optical fabrication industry for many years. These tools have enabled the cost-effective and deterministic manufacturing of aspheres with accuracies that previously would have never been possible. OptiPro Systems' newly developed UltraForm Finishing sub-aperture polishing machine provides an easy-to-use user interface that seamlessly integrates all of the required inputs for its polishing process. A discussion of these inputs and the sub-aperture process flow for UltraForm Finishing will be presented.


    Asphere and Freeform Measurement 101

    The precision optics industry is gradually moving toward increasingly complex optical designs. Aspheres are becoming a large portion of manufactured optics. Metrology for these optical shapes is a challenge and various measurement methods have individual strengths and weaknesses. OptiPro has developed a novel solution named UltraSurf, a non-contact measuring system using state of the art, precision motion control. OptiPro designed the UltraSurf to further the manufacturing capabilities of companies producing complex precision optics. Common asphere and freeform metrology is presented along with how the UltraSurf fits in.
