•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)

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
