The value in ( ) is with accessory lens or auxiliary lens attached |
| Myopia |
0 to –19.00D in 0.25D step (0.12D step) |
| Hyperopia |
0 to +16.75D in 0.25D step (0.12D step) |
| Astigmatism |
0 to –6.00D (– 8.00D) in 0.25D step (0.12D step) |
| Cross-Cylinder |
±0.25D (±0.37D and ±0.50D as option) |
| Phoria and vergency |
20∆ to 0 to 20∆ by 1∆ step |
| |
Inner 40∆ |
| |
Outer 40∆ (50∆) |
| |
Upward and Downward 40∆ (46∆) |
| Near vision test |
Main optical axes of both lenses converges by means of a tilt mechanism at 40cm in front of the eyes at 64mm P.D. If P.D. for far vision is less than 54mm, converging operation stops. |
| Binocular balance test |
Rotary prism and polarizing lens methods are available. |
| P.D. |
48 to 75mm by 1mm step |
| Level adjustment |
More than 4.5° for right and left banks |
| Dimensions |
335 (at 64mm P.D. setting) x 97 x294mm |
| Weight |
4.5 kg |

Synchronised cross cylinders The Topcon VT-10 phoropter is equipped with a cross cylinder that automatically rotates in conjunction with the set cylinder axis. Special gearing automatically synchronises the rotation of the loupe each time you change cylinder axis correction.
Easy convergence system A convergence system in the Topcon VT-10 phoropter allows natural conditions for near testing.
Multi coated lenses for superior optical performance The coating of the lenses in the VT-10 elimates flare, ghost images and reflections. The multi coated assure clearer, brighter images with improved contrast.
