Super Luminescent Diode (SLD)
Super Luminescent Diode is an edge-emitting semiconductor light source based on super luminescence. It uses the high power and brightness of laser diodes providing a sharper image compared to LED. It allows for quick and accurate measurements of patients with cataracts, corneal opacities, IOL’s, and post LASIK.
Dual Zone
Exclusive dual zone refractive measurement utilizing double-ring technology to measure two pupil zones supplies information based on pupil size and provides more robust objective data as a starting point for subjective refractions.
