| Wide testing range |
The testing range available with the 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 are possible thanks
to the 20 range (1 increments) of the precision-geared rotary
prism loupes. The VT-10 is also available in plus or minus cylinder models. |
| |
| Synchronized cross-cylinders |
| The most significant time-saving feature of the 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 and 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. |
| |
| Simple convergence sytem |
| Percise measurement at both near and distant testing for optimal results. One quick adjustment of
the dual convergence levers and the VT-10 provide total accuracy in near vision testing
measurement. |
| |
| Sealed optics |
| The examination apertures feature cover lenses for convenience and protection. Dust, eyelashes,
etc. can't get in, and the lenses are easily removed for simple cleaning. The patient always has
a bright, clear image to view. (Standard accessories include face shields that can be sterilized
for optimum comfort and hygiene.) |
| |
| Versatile adjustments |
| Convenient dual controls make it easy for the operator to adjust interpupillary distance, in a
range from 48mm to 75mm. The mechanism is sealed for protection and smooth functioning. An easy-to-read scale provides 1mm graduations, and a vergence adjustment controls reductions in P.D. during near
testing. |
| |
| A wide range of versatile auxiliary lenses |
| The 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 |
| 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. |
| |
| Accessories |
| The holder for rotary near point cord mounts to a study rod with a distance scale from 5 to 28
in. - centimeter and diopter scales are included. A hinged bracket moves it into position
immediately, or raises it out of the way. Accessory lenses come in an accessory box, holding dual
sets or -0.12D and -2.00D cylinder lenses. |
| |
| Multi-coated lenses for superior optical performance |
| Every lens used in the 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. |
