Features


A  New leveling mechanism

B  Fingertip adjustment for sphere power control

    Just the right figure from 0 to -19.00D and 0 to +16.75D obtained with light, fingertip control of the fast feed dial. Optional ±10.00D lenses are available.

C  Measuring astigmatism 

    Readings 0 to -6.00D, which become possible up to -8.00Dwith accessory lenses -2.00D , Used in combination with the cross cylinder for precision measurement.

D  Cross cylinder (±0.25D)

    Tests are speeded up by eliminating the need for axis adjustment, a very efficient Synchronizing mechanism being provided and the loupe is readily turned by means of the knob.

E  Rotary prism

    The wider 1D spacing the 20D range simplifies reading and incorporation into the main body of the instrument means that a maximum field of view is obtained.

F  Unique new convergence system mechanism

    Convergence lever control for precision near point readings.

G  Wide range of auxiliary lenses combinations (See details on the page 6)

H  Precision Machined to finest tolerances

    The use of top quality bearings and elimination of the need for periodic lubrication

Two colors choice
