Spherical, cylindrical and prismatic lenses in the range ± 0.05 dioptres to ± 25 dioptres
An important factor in achieving accurate production of spectacle lenses is the maintenance of consistent standards of lens power in the ophthalmic examination, lens manufacture and subsequent spectacle fitting. Consistent measurements of power may be assessed in all these stages by using focimeters and spherometers which have been calibrated with suitable reference lenses.
NPL offers a range of services in support of accurate ophthalmic measurements including the calibration of customer supplied reference lenses, the provision of boxed sets of calibrated ophthalmic reference lenses, and the calibration of focimeters.
