How to choose this product
A lensmeter measures the distance between the surface of a lens and its focal point. A simple calculation yields lens power in diopters.
These instruments are used for centering and verification operations during the manufacture of eyeglasses.
Measurements may be carried out manually or automatically. Certain models are capable of determining UV transmittance, pupillary distance or other parameters.
How to choose
Precision is clearly the primary characteristic to consider when choosing a lensmeter.
