VT-10 - phoropters
• Compact design
• Easy to operate
• Wide measuring ranges
• Convergence system
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.
A convergence system in the Topcon VT-10 phoropter allows natural conditions for near testing.
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.

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) |
|
Phoriaandvergency |
20∆ to 0 to 20∆ by 1∆ step |
|
Inner 40∆ |
|
|
Outer 40∆ (50∆) |
|
|
UpwardandDownward 40∆ (46∆) |
|
|
Nearvision 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. |
|
Binocularbalance 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 |
