Interference-Phase Contrast Microscope

Differential interference contrast (DIC) microscopes utilize the principle of light interference, where a beamsplitter built into the objective divides the light beam into reference and sample beams. The two beams reflect and superimpose to produce interference fringes. By analyzing the deformation of these fringes, nanometer-scale height differences on the sample surface can be detected. This technique is used to observe internal structures of transparent samples, measure film thickness, and analyze surface roughness.
Selection
Select reflection or transmission type based on the sample material; consider vertical resolution (up to 0.1 nm) according to measurement accuracy requirements; choose the objective magnification based on the observation range; pay attention to environmental vibration isolation requirements; check whether the software has 3D reconstruction capabilities; confirm that the camera's pixel count and sampling rate match the detection needs.
