Spherometer
Mastering the radius
Fast and efficient radius measurement of lenses
Spherometers made by TRIOPTICS are used worldwide in hundreds of optics companies and laboratories for the precise measurement of the radius of curvature of concave and convex lenses. The radius of curvature is determined by the tactile measurement of the sagittal height of the curved lens surface. This high-precision radius measurement by means of Spherotronic® and SpheroCompact®, which can also be used for calibrating test plates, represent the industry’s standard today. In addition, the long-term accuracy and automated functions of our spherometers are highly appreciated in laboratory and manufacturing environments.
The high-precision ruby gauge head of the central encoder enables radius measurements with a measurement accuracy of up to ±0.005 %.
SpheroCompact®
Radius measurement in production
The SpheroCompact® allows radius measurements in production with accuracies of up to ±0.05 %.
- Multi-purpose use, particularly for highly curved convex and concave surfaces because small radii of up to +2.5 mm and -4 mm especially can be measured
- Its compact design allows SpheroCompact® to be used flexibly
- Spherometer optimized with regard to price and performance for use in manufacturing
SpheroCompact® HR
Precise and reproduceable
The SuperSpherotronic® HR offers excellent accuracies of up to ±0.01 %.
- Radius measurement of convex and concave surfaces up to +3 mm and -6 mm
- Excellent precision for the measurement of highly curved surfaces with a large lens diameter by means of an increased travel of 60 mm
- Extreme resistance to mechanical deformation thanks to the use of tungsten carbide balls in the ring
UltraSpherotronic®
Highest precision
With an accuracy of up to ±0.005 % the UltraSpherotronic® reaches the highest measurement precision worldwide.
- Radius measurement of convex and concave surfaces up to +3 mm and -6 mm
- Excellent precision for the measurement of highly curved surfaces with a large lens diameter by means of an increased travel of 60 mm
- Extreme resistance to mechanical deformation thanks to the use of tungsten carbide balls in the ring
