Phi-Theta 3D Scanner | Rotational Positioning System for the Inspection of Contact Lenses (living transplants and synthetics) Ultra-precise measurement of living eye lenses Certain diseases or the individual properties of a cornea do not allow patients to implant or lens transplant artificial lenses. In this case, a living eye lens must be transplanted. In order to assess living lenses with regard to their quality, surface quality and patient suitability, they have to be measured completely and with high precision. Ordinary laser measurement of living lenses is almost impossible. The biological tissue is extremely sensitive to light, so that it is destroyed by the laser when the light is static and / or centered. To solve this scanning application, a lens holder with the living lens is attached. This turns at 300rpm. The surface is measured by an optical sensor. The sensor is swiveled by + -60 ° during the rotation. This enables a complete 3D measurement of the lens without damaging the biological material. Highly precise positioning of the light path Ideal for rotational 3D inspection of grafts Suitable for the inspection of synthetic contact lenses with special, highly sensitive surfaces High-precision 3D scans of optical properties with repeatability up to 0.05°
