Basic Principles of POMEAS 3D White Light Interference Profiler

POMEAS 3D White Light Interference Profiler WLI-1000 is based on the white light interference principle, which utilizes the interference fringes generated by the interference of light emitted from a white light source, and accurately calculates the surface topography and profile information of the object under test by measuring the displacement and deformation of these interference fringes. Its measurement accuracy can reach the nanometer level, which can realize the precise measurement of tiny surface topography.

3D White Light Interference Profiler for Optical Manufacturing Applications

Surface quality inspection of lenses and prisms：Lenses and prisms are indispensable components of optical systems and their surface quality directly affects the performance of the optical system. The surface morphology and roughness of lenses and prisms can be measured non-contact using a 3D white light interference profiler to ensure that their surface quality meets design requirements.

Precision measurement of optical molds：In the optical manufacturing process, the precision of the mold directly determines the performance of the final product. 3D white light interference profilometer can accurately measure the surface morphology and contour information of the mold, providing reliable data support for precision machining and correction of the mold.

Thickness Measurement of Optical Thin Films：Optical films are an important part of optical manufacturing, and their thickness and uniformity have a significant impact on optical performance.3D white light interference profilometer can accurately measure the thickness and uniformity of optical films, providing a strong guarantee for the quality control of films.

Advantages of 3D White Light Interference Profilers in Optical Manufacturing

Non-contact Measurements：Compared with the traditional contact measurement, 3D White Light Interference Profiler adopts the non-contact measurement method, which avoids the damage and pollution to the measured object during the measurement process.

High Precision Measurement：The 3D White Light Interference Profiler offers extremely high measurement accuracy, enabling precise measurements on micron and even nanometer surfaces.

High Efficiency Measurement：Thanks to the advanced interferometry technology, the 3D white light interferometric profiler can accomplish a large number of measurement tasks in a short period of time, improving the measurement efficiency.
