The GS-1 incorporates a unique one-of-a-kind multimirror prism lens designed specifically for this system. Sixteen surfaces capture 360 degrees in one smooth measurement sequence. The NIDEK multimirror prism lens was developed by optimizing each surface for the perfect angle.

Automated Angle Detection provides guidance for capturing the iridocorneal angle. Through diligent research, NIDEK developed Angle Detection that can recognize angles regardless of eye color.

The GS-1 composes linear and circular images of iridocorneal angle structures when the entire 360 degrees are captured.
