The cross cylinder loupe is synchronized with the control knob to easily change the cylinder lens axis.Corneal Aligning Device
Used to align the corneal vertex of the patient and set the patient’s cornea in the correct position (at 12mm). Measurement should be made at the “0” position of the scale.Convergence System
Converge the system for near testing by placing the levers inward and test for distance when the levers are placed outward.Rotary Prism
0-20∆ in 1∆ steps allows for vertical and horizontal measurements.
Near point scale and Chart
The Near Point Chart contains a rotatable disc with 12 kinds of tests on both sides. The chart is set on a rod which can be measured in cm, in or diopters. The rod is 67cm (26.4in) in length.Accessory Lenses
