About This Product
A lens meter reads the power of a spectacle lens: the lens is placed on the stand and the target is brought into focus through the eyepiece. The readings show the spherical power, the cylinder axis and any prismatic power. This instrument can be tilted from 30° to 90° to give a clear view of the corona, and its eyepiece focusing is adjustable. It is used in optics practicals and optical dispensing.
