Name: MirauWhite Light Interference Objective
Name： Mirau Obj
Application Areas:
Mirau White Light Interference Objective is commonly used for 3D surface topography measurement, and is one of the most important accessories in a white light interferometer. It can also be installed on a metallurgical microscope to analyze the surface irregularity of samples. By interpreting the interference fringes or using corresponding software, users can calculate relevant parameters of the 3D surface topography.
Features:
1. Domestic white light interference objective with independent core technology
2. Compact structure, high interference fringe contrast
3. Applicable to various types of infinity-corrected metallurgical microscopes
Optical Design: Mirau Infinity-Corrected White Light Interference Structure
