Wide Range of Sphere Power Readings:
Spherical power ranges from -19.00D to +16.75D in 0.25D steps. By using the unit’s auxiliary lens, you can measure -29.00D to +26.75D in 0.12D steps. In addition, both sphere power knobs can be quickly changed in 3.00D steps for added convenience.
Cross Cylinder Synchronization:
Quickly and conveniently perform astigmatic testing. The cross cylinder loupe on the ERF-3600 is conveniently synchronized with the control knob to easily change the cylinder lens axis.
Measuring rotary prism couldn’t be easier. The ERF-3600 allows for vertical and horizontal measurements of 0 to 20∆ in 1∆ steps.
Impressive Range of Cylinder Powers and Axis:
Measure cylindrical power ranges from 0 to -6.00D in 0.25D steps. Or, use the auxiliary lens and measure ranges from 0 to -8.00D in 0.12D steps. The cylinder axis ranges from 0°-180° in 5° steps.
Interpupillary Distance Adjustment:
Located on both sides, the PD knobs enable smooth and quick adjustment. The pupillary distance adjustment ranges from 48mm-80mm in 1mm steps.
Auxiliary Lenses Included:
For enhanced flexibility, the ERF-3600 is provided standard with 0.00D, -2.00D, and -0.12D cylinder auxiliary lenses.
