Optimized for outstanding performance with either a Streak or Spot beam with a simple bulb change. With up to 600 lux of brilliant Halogen illumination, the Professional Combi guarantees you enough light to refract even the most difficult eyes. This is the ONLY Retinoscope allowing rapid confirmation of neutralization. In both Streak and Spot modes you can change the beam from divergent to convergent enabling you to cross check the accuracy of the neutral point. The ability to double check neutralization in the upper position guarantees the assessment is correct the first time and every time. The Professional Combi offers improved 360° access to a single control for both rotation and convergence adjustments. The precision movements are achieved by use of rare earth magnet technology.
