The TRIOPTICS Spherometers are on use in hundreds of optical companies and laboratories worldwide for precise measurement of radius of curvature. Our spherometers have become an industry standard for ultra accurate radius measurement and calibration of test plates. The long term accuracy and automated features make our spherometers the preferred instruments for laboratory and production environments.
The Spherometer® radius measurement and calibration instruments can be used for concave and convex lenses. The spherometer measures the sagittal height of the curved surface of the lens. Trioptics offers three different types of Spherometers for different use and accuracy, but all includes mainframe components out of stainless steel and supporting balls with an accuracy less than 1 micron.
