Description
Adjusting Sphere Power Readings / Cylinder Power and Axis
- Exact adjustment from -19.00D to +16.75D in 0.25D steps. The rapid feed dial allows fast examination within ±3.00D. With accessory lenses, readings up to ±0.12D are possible.
- Optional auxiliary lenses ±10.00D extend the range to -29.00D ~ +26.75D.
- The cylinder lens, graduated in 0.25D steps, allows adjustment from 0 to -6.00D (up to -8.00D with -2.00D accessory lens).
- Cylinder axis adjustable from 0° to 180° in 5° steps.
- Rapid adjustments using two knobs aligned on the same axis.
- The cross-cylinder loupe rotates automatically through a synchronized mechanism linked to the control knob.
System
Precise measurement is possible with the lens set at the correct angle for near vision (closing the convergence lever inward) or distance vision (opening it outward).
This aligns the optical system with the patient’s natural convergence, ensuring accurate testing through the correct optical centers.
Near Point Scale and Chart
The scale can be graduated in inches, centimeters, and diopters. It can be positioned at any working distance and stored upright when not in use.
The Near Point Chart includes a rotatable disc with 12 test types on both sides. Total scale length: 67 cm / 26.4 in.
Corneal Aligning
Used to align the corneal vertex at the correct position (12 mm from the tester lenses). Measurements should be taken at the “0” position of the scale.
Adjustment Levels
Adjustment range from 45 mm (1.77 in) to 80 mm (3.15 in), with a clear 1 mm (0.04 in) scale.
Convenient knobs on both sides allow smooth and fast adjustments.
Leveling is easy with a one‑touch leveling knob.
Rotary Prism
Accurate readings up to 20∆ in 1∆ steps.
A click‑stop mechanism allows measurement of horizontal/vertical strabismus and heterophoria.
Using both prisms, readings up to 40∆ are possible for binocular balance testing.
Accessory Lenses
Includes three spare lenses: -2.00 CYL, -0.12 CYL, and 0.00 CYL.
