Non-contact thickness measurement optical sensor "CHRocodile 2 Series"

A wide range of probes that can measure with high precision from thin films (a few micrometers) to thick films (780 micrometers). Suitable for wafer inspection applications as well.

The "CHRocodile 2 series" is a non-contact sensor capable of in-process measurement of wafer thickness with sub-micron resolution. It is also used for quality control through sampling. In addition to the semiconductor industry, it is adopted in consumer electronics, glass manufacturing, and the medical field, making it suitable for measuring the thickness of transparent materials, coating thickness, and simultaneous measurement of multiple layers (up to 16 layers). 【Features】 - Wide range of thickness measurement, compatible with various materials A rich lineup of probes covers thickness from thin films (a few micrometers) to thick films (780 micrometers). Two principle methods can be selected according to the material. - High resolution (sub-micron, minimum 1nm) High-resolution measurements based on "chromatic aberration confocal method" and "spectral interference method." - Contributes to reducing development costs and shortening development lead times, with a software development kit (DLL, etc.) available for equipment integration. - Extensive track record across multiple industries Semiconductor industry, consumer electronics, glass manufacturing, medical field. *For more details, please refer to the materials.
