Spherometers

Spherometers manufactured by TRIOPTICS are used worldwide in hundreds of companies and optical laboratories for precise measurement of the radius of curvature of concave and convex lenses.
The radius of curvature is determined by tactile measurement of the sagittal height of the curved lens surface. This range of high-precision radius measurement instruments can also be used to calibrate test plates, and today represents the industry standard.
What’s more, the long-term accuracy and automated functions of our spherometers are highly appreciated in laboratory and manufacturing environments.
TRIOPTICS offers 3 spherometer models for measuring the radius of curvature of optical components or precision molds.
3 performance levels are available for measuring ROC from +/- 0.05% to +/- 0.005%.
