The Ezer EZ-RET-2600 augmented light output makes refractions much more easy by producing clean and sharp streaks.
Description
The EZ-RET-2600 is designed to help the practitioner to easily determine the patient's prescription. The streak retinoscope is easy to use, fast, accurate and especially valuable in determining the axis of astigmatism.
- Multi-coated optics
- A single control sleeve for vergence and rotation & comfortable operation
- Dustproof, maintenance free
- Metal handle-for long lasting operation
- Superior streak quality enables easier and quicker refractions, including in patients with small pupils
- The powerful bulb ensures easy recognition of neutralization
- The lowest position gives a divergent beam
- Lamp type: Halogen and LED
