158 OPHTHALMOLOGY • INSTRUMENT AND BOOK SUPPLEMENT 1987

automatically synchronized cross cylinder rotation which corresponds to its built-in cylinder axis. Its convergence system provides the widest and most accurate overlapping field of vision in near testing measurements.

Specifications Range of measurement of spherical lenses:

Combination of two sphere power dials. + 16.75 D. to -19.00 D in 0.25 D. steps by rotation of only the weak sphere dial.

Range of measurement of cylinder lenses: 0.00 D. to -6.00 D. With 0.25 D. steps.

Plus cylinder lens system is optional. A pair of 0.12 D. cylinders in accessory cells permits

refinement to 0.125 D. steps. A pair of 2.00 D. cylinders in accessory cells extends cylinder power range to 8.00 D.

Cylinder axis: 360° (Doubles oo to 180° scale) with 5 steps. '

Cross cylinders: The standard cross cylinder cells supplied are ±0.25 D. (±0.37 D. and ±0.50 D. cross cylinders are available as optional parts).

Rotary prisms: Each rotary prism unit has a range of 20.1 with 1.1 scale graduation. Paired, prisms give 40<1 in any base direction.

P.D. adjustment range: 48 mm to 75 mm with 1 mm scale graduation.

Vertex distance: 13.75 mm Reading distance: 5" to 28" (Centimeter and dioptor

scales.) Auxilary dial: 10 auxiliary lenses and two open

apertures. "0" (Open aperture), "R" (Retinoscope lens, + 1.50 D.), "P" (Polarizing lens), "WMV" or "RMV" (Maddox rod, vertical white, left eye. Red, right eye.) "WMH" or "RMH" (Maddox rod, horizontal white, left eye. Red, right eye.) "RL" (Red lens), "+0.12" (+0.12 sphere lens), "PH" (Pin hole), "6dU" (6 base-up prism), "±0.50" (±0.50 D. fixed cross cylinder), "OC" (Occluder).

Net weight: 9.5 lbs. Price $3137 (Woodlyn Classic Refractor with minus

cylinder) $3137 (Woodlyn Classic Refractor with plus cylinder)
