Delicate and attractive design.
The precision of the instrument implies a delicate managing when
realize the examination of myopia and astigmatism.
The crossed cylinder and the gyratory prism offer a wider field of vision.
Use a special mechanism in the system of convergence.
The range of test is wider due to the great selection of auxiliary provided
Major precision and permanence due to the oiled bearings.
Together with the chart projector there can be examined a wide range
of visual functions (vision binocular, estereopsis, aniseiconia, etc).
The surfaces of the lenses have high quality cover.
The adjustment of the level can be realized easily with one operation
Wide range of adjustment from 48 mm to 80 mm and easy reading
scale with 1mm of graduation.
Readings adjustments of spherical power
The adjustment can be realized with facility from-19.00D to + 16.75D in
steps of 0.25D steps and the dial of spherical power allows an ocular
rapid examination for + 3.00D with the incidental lenses: + 0.12D and
up to(even)-29.0D - +26.75D
Adjustment of the cylindrical power and Axis
The cylindrical lens graduated in steps of 0.25 D allows an adjustment
from O ~-6.00 and with the incidental lens-2.00D, it is possible to extend
the range of adjustment up to -8.00D.
The axis of the cylinder can adjust from 0 ? to ~ 180 ? in 5 steps
Crossed cylinder (+ 0.25)
The crossed cylinder, across a special mechanism totally synchronized
with The knob control of the axis of the cylindrical lens, it turns in
automatic form towards Corresponding axis whenever there is changed
the axis of the cylindrical lens.
The readings can be taking with accuracy up to 20 ∆ in 1 ∆ graduated
The automatic stop allows the measurement of the strabismus and
heteroforia horizontally and vertically.
It is possible to take readings of up to 40 ∆ and test the balance of the eye.
It is possible to realize a precise measurement if places the lens in an
adecuated position for an examination of near vision and if the distance
Corneal Aligmnet Device
Across the sight, it is possible to align the corneal vertex of the patient
and place the cornea of the patient in the correct position to 12 mm of
The measurement must be realized in the position "O" of the scale
Scale of Near Point and Chart
The scale is graduated in "inches", "centimeters" and "diopters".
The chart of near point contains a giratory disc with 12 classes of tests
In both sides.
The scale is of 67 cm of length
Spherical lenses: +16.75D to -19.00D (0.25D steps) two-sphere power
Cylinder lenses: 0.00D to -6.00D (extendable to -8.00; 0.25D steps,
refinable to 0.125D); plus system optional
Cylinder axis: 360? (double 0-180? scale, 5? steps).
Cross cylinders: ?0.25D?
Rotary prisms: 20? each (1? scale graduation), paired gives 40? in any
P.D. adjustment: 48-75mm (1mm scale graduation).
Vertex distance: 13.75mm.
Reading distance: 5-28" (plus cm & D scales).
Auxiliary dials: 10 lenses and 2 open apertures
