Line scan microscope film thickness measuring head

Use the measuring head developed by our company.
Line scanning film thickness measurement head, which can measure photoresist and OLED materials with high precision through white reflection spectrum film thickness analysis and processing.

feature

Microspectroscopy  High-precision measurement of shape and film thickness changes in tiny areas
line scan By using the line scan method, the measurement length is variable, and a wide range of distribution evaluation can be performed.
Scalability Supports measurement over the entire surface of a large board by arranging multiple heads and extending them in the width direction
Material properties Equipped with refractive index and extinction coefficient measurement functions.Changes in material properties can be monitored and tracked
Online measurement Depending on configuration, inline support is also available
other Multilayer film analysis Film thickness distribution map Supports statistical processing of in-plane distribution
