Choice of minus or plus system. The cylinder axis control is concentric with the cylinder power knob. The control knob rotates a full 360 degrees and is surrounded by the axis scale. An axis reference scale at the main aperture speeds retinoscopy.
Convenient P.D. adjustment. Simply turn a knob on either side for velvet smooth adjustment. The easy-to-read scale is in 1 mm graduations.
With implementation of Ful-Vue vergence for near testing, P.D. calibration is automatically compensated.
Simplified leveling control knob. For fast, precise positioning.
Highly accurate bi-loupe turret. Two loupes mounted in a single rotating turret - in a single plane - are positioned very close to the instrument aperture. This means a shorter optical path, wider field of view, and completely overlapping fields during near testing.
Time-saving strong sphere control. Allows you to dial power changes in 3.00D steps.
Precision geared rotary prism. 1
scale graduations permit more accurate interpolation of readings to 1/2
or even smaller fractions. Precision components assure positive, smooth control over a 20
range through a convenient finger roll knob.
Convenient optical corneal aligning sights. Located on the practitioner side for effortless vertex measurement.
The most useful selection of auxiliary lenses. Ten lenses plus 2 open apertures in each battery, including Retinoscopic lens, Green or Red Lens, Vertical and Horizontal Maddox Rods, Sphere, Pin Hole, Dissociating Prisms Fixed Cross Cylinder, Occluder and polarizing analyzer.
Extensive built-in cylinder range. 0.00 through 6.00D in 0.25 steps.
Optically additive lenses. Normally, the effective power combination of two or more lenses can't be obtained accurately by simply adding their individual powers. But these specially computed lenses and lens separations mean designated powers can be simply added together to give the effective power of any combination.
Single dial sphere control. Allows you to dial any sphere lens power in 0.25D steps.
Convenient reading rod, near point card holder, and Rotochart. Full 28 in. rod to trifocal range. Smoothly gliding, rotating card holder. Unique Near Point Rotochart exposes 12 sets of test characters without changing multiple cards.
Sterilizable face shields. Can be washed, soaked in alcohol, or boiled.
