WSI-TG

White Light Source Thickness Measurement System

Point spectroscopy thickness measurement system using white light source and spectrometer.
Compact and suitable for short-distance measurement, compatible with tabletop and portable measurement.

WSI-TG is a point spectroscopy thickness measurement system using white light source and spectrometer. It measures thickness changes in real-time and is often integrated into production lines.

Like LSI-TG, non-contact and non-destructive measurement is possible, minimizing impact on samples by using light as the measurement medium. It excels at short-distance measurement and the entire system is compact. In addition to equipment integration, it is also suitable for tabletop measurement and portable measurement.

With a broader measurement wavelength range than LSI-TG, it supports thin film measurements of 10μm or less in Si-equivalent. It is optimal for measuring thin objects such as coating layers.

Features

Compact Design

The entire system is compact and requires minimal installation space.

Short-distance Measurement

Excels at short-distance measurement, usable in sealed environments and narrow spaces.

Tabletop & Portable Compatible

Flexible enough to be used as a tabletop or portable measurement device.

Wide Wavelength Range

Wide usable wavelength range supports thin to thick films.

Thin Film Measurement Capable

Can measure thin samples below 10μm in Si-equivalent.

Non-contact & Non-destructive

Light-based measurement causes no damage to samples.
