Streak Retinoscope
Specifications:
3.5V Streak Retinoscope is designed exclusively to determination of the refraction of the eye.
The streak retinoscope is found by most practitioners to be easily use, fast and accurate in determining the axis of astigmatism.
| Characters |
| Multi-coated optics |
| a single control sleeve for vergence and rotation, comfortable operation. |
| totally dustproof and maintenance free |
| Superior streak quality enables easier and quicker refractions-even patients with small pupils. |
| The powerful, bright bulb ensures easy recognition of neutralisation. |
| Working distance: |
1m |
| Adjustalle range of streak: |
3mm-20mm |
| Streak Rotation: |
360 degrees |
