Confocal laser microscopy: the savior of material surface roughness

Posted Date: 2024-01-16

In industrial production and scientific research, the roughness of the material surface involves the quality and processing effect of the material. It determines the microscopic morphology and performance of the material surface, and directly affects the mechanical, physical and chemical properties of the material.Traditional roughness detection methods are often limited by problems such as low resolution and slow measurement speed, and cannot meet the detection needs of fine material surfaces.Laser confocal microscopy has become a powerful tool for material surface roughness detection due to its advantages such as high resolution, high sensitivity and high measurement speed.

Why choose a confocal microscope to measure roughness?

As a high-resolution microscope, laser confocal microscopy can accurately and quickly measure the microstructure of the material surface and provide more accurate and comprehensive roughness information.Such as VT6000 confocal microscopeBased on the principle of pinhole confocal technology, when measuring the surface topography and roughness of complex parts, it has better imaging effects on products with large inclination angles, and can solve many measurement problems in a targeted manner.:

1. For material surfaces with micro structures or micro textures

Traditional detection methods often cannot accurately describe the roughness. Laser confocal microscopy can reveal tiny structures and conduct precise measurements through its high-resolution imaging capabilities, effectively solving the limitations of traditional methods.

2. For curved or non-uniform material surfaces

Traditional methods are often limited by problems such as limited measurement range and incomplete data. Laser confocal microscopy can obtain large-area surface data through scanning technology and achieve a comprehensive and accurate description of the roughness characteristics of curved surfaces or non-uniform materials.

3. Restrictions on materials

Laser confocal microscopy can also be used to detect the roughness of a variety of materials, including metals, ceramics, plastics and other materials, and has broad application prospects.

Laser confocal microscopy is used to measure the surface topography and roughness of complex parts

The laser confocal microscope is based on the spinning disk confocal optical system, combined with high-stability structural design and 3D reconstruction algorithm to form a measurement system. It can achieve spatial resolution up to sub-nanometer level (height resolution 0.5nm; width resolution 1nm.), achieve non-contact, high-resolution material surface detection, and avoid surface damage and contamination that may occur in traditional methods. Problem; With the three-dimensional imaging function, the three-dimensional topography information of the material surface can be obtained, and various parameters of the surface can be accurately analyzed and quantified, providing more comprehensive and detailed data support for the roughness evaluation of the material surface.
