Phoropter
Topcon VT-10
Precision
and convenience are a tradition in high quality TOPCON optical instruments.
The Phoropter Topcon VT-10 advances this tradition still further, making
refraction quicker and easier than ever before, providing unequaled performance
and exceptional versatility. Precision in design and workmanship guarantees
accuracy in refraction measurements-accuracy that won't deteriorate even
after long years of use.
Total quality from TOPCON means you can have total confidence
in the performance you'll enjoy from the Phoropter Topcon VT-10.
Features
- Wide Testing Range
The testing range available with the Phoropter Topcon VT-10
is extraordinary, the standard cylinder power range extends to 6,000 in
0.25D increments. In addition, auxiliary lens sets are incorporated to
fine-tune cylinder power measurements to 0.12D increments or extend cylinder
power range to 8.00D. Accurate prism reading even below 0.5 prism are
possible thanks to the 20 prism range (1 prism increments) of the precision-geared
rotary prism loupes. The Phoropter Topcon VT-10 is also available in plus
or minus cylinder models.
- Synchronized Cross-Cylinders
The most significant time-saving feature of the Phoropter
Topcon VT-10 is its synchronization of cross-cylinder loupe rotation to
cylinder axis adjustment. Special gearing automatically synchronizes the
rotation of the loupe each time you change cylinder axis correction. The
result? You simply read a single scale, one time, after completing a full
series of axis checks. The bi-loupe turret lets you index power or axis
loupes with a single touch.
- Easy Controls & Clear Scales
Control of cylinder axis and power testing is amazingly
simple; concentric control knobs within a double-calibration axis scale
make adjustment a quick, one hand action through the full 360° range.
The axis scale reads in 5° increments, with 15° markings. An additional
axis scale is located at the main aperture, for convenient reference during
retinoscopy. The low position of the control knobs keeps the operator's
hands out of the line of vision.
- Versatile Adjustments
Convenient dual controls make it easy for the operator to
adjust interpupillary distance, in a range from 48 mm to 75 mm. The mechanism
is sealed for protection and smooth functioning. An easy-to-read scale
provides 1 mm graduations, and a vergence adjustment controls reductions
in P.D. during near testing.
- Wide range of Versatile Auxiliary Lenses
The Phoropter Topcon VT-10 comes with a full complement
of versatile auxiliary lenses - 10 different lenses plus two open apertures,
any of which can be indexed into position with one-touch speed and convenience.
A red lens / green lens shift, for example, is immediately available for
binocular vision testing . The auxiliary lens plate has a flat black finish
to prevent stray reflections during use.
- Fast, Precise Results
Phoropter Topcon VT-10 incorporates a single-dial power
control that lets the operator quickly dial in any spherical power from
+16.75D through 0 to -19.00D, in 0.25D increments. To make settings faster,
a strong sphere control allows adjustment in 3.00D steps; the auxiliary
lens knob provides for fine-tuning in 0.12D increments for absolute accuracy.
- Multi-coated lenses for superior Optical Performance
Every lens used in the Phoropter Topcon VT-10 receives a
special multi-coating that eliminates flare, ghost images and reflections.
In addition, the multi-coating assures clearer, brighter images with improved
contrast and excellent color fidelity.
