<p><strong>Wavefront Technology Ensures Reliable Measurement</strong></p> <p>By applying wavefront technology with Hartmann sensor, L900 has 145 measuring points which enable it to provide highly accurate measurement in fast speed. It uses green light LED which does not require ABBE compensation. In this case, the result will be more precise compared with traditional auto lens meter technology. Uniquely designed optical system enables L900 to measure much wider spherical range up to &plusmn;35.00D. This helps to measure the lens for high myopia patient and other lenses in complicated cases.</p>
