1. The laser always irradiates the sample vertically to obtain a Raman image without distortion Accurate image information also obtained when using 3-D imaging A wide area sample measurement using only laser scanning (50 µm x 50 µm using a 100X objective lens) Laser Objective lens Sample VertiScan Laser Scanning

2. VertiScan Conventional Laser scan VertiScan Laser Scanning

3. Sample Raman image VertiScan Laser spot shape Laser Objective lens Sample Consistently complete circle No distortion, wide range Raman imaging Conventional Laser scan Objective lens Sample area far from the center of the objective lens is irradiated from an oblique laser beam. A measurement point of the internal sample can be greatly distorted. Spot far from center is ellipsoidal with low spatial resolution Distorted Raman imaging for outside sample positions, distortion-free imaging in center of sample Laser spot shape Sample Raman image Laser always irradiates the sample vertically
