In-line/off-line mapping-type birefringence measurement system

KAMAKIRI Birefringence Measurement Module

Installed in your equipment
Minimum configuration inspection system for individual customer

The KAMAKIRI birefringence measurement module is an effective product in situations where installation on the production line is difficult in terms of space. We provide a position adjustment mechanism and optical correction data (optical calibration data) suitable for the customer’s environment to support stable measurement. If multiple units are installed, measurement for all units starts by synchronizing the measurement start signals.

Since the operation and analysis use the same software as KAMAKIRI MEM-LS, the functions of real-time measurement and post-analysis are substantial.

KAMAKIRI STS-LS

KAMAKIRI STS-LS is the only system capable of inspecting the entire surface of films produced continuously for a long period of time. It supports a live display function to check results on the site and an pass/fail judgment function, to enable early detection of defects.

KAMAKIRI X-Stage

KAMAKIRI X-stage is a compact desktop inspection system that is a line scan type. Since the basic algorithm is unified with the inline system, it can be used as an introductory machine before introducing the inline system.

KAMAKIRI MEM-LS

KAMAKIRI MEM-LS can measure and inspect the part of the line you want to see with one camera and the part in the width direction of the film in-line, just like a sampling inspection.As a result, the sampling inspection time is shortened, the production of defective products can be stopped quickly, and the yield can be expected to increase.
