3D Laser confocal profile

MSS new 3D Laser confocal profile can provides non-contact, nanometerlevel profile, roughness, and film thickness information on all kinds of samples, and indicates which metrics are most critical for evaluation.

– 3D Laser confocal profile niches

• Non-destructive & non-contact analysis

• Fit to all kinds of samples (size, height, hardness, ...etc.)

• Fast analysis speed

• Better spatial resolution, 0.2 um (Optical profile is 0.38 um)

• Better vertical (z-direction) resolution

• Can be measured with an albedo larger than 5%(perfectly for Micro Lens)

• Can be a complementary tool to AFM
