90° Turning Telecentric Illumination for Precise Inspection & Measurement | TI Series

Product Description

TI Series Telecentric Illumination is a high-performance 90° Turning Telecentric Illumination, also known as coaxial telecentric light, engineered for demanding machine vision inspection and metrology tasks. Through complete light coupling, the TI Series increases the distance between the object and the illumination source, enabling more uniform illumination and stable imaging performance across the entire field of view.

By effectively removing border effects, TI Series delivers higher edge contrast, significantly improving measurement repeatability and dimensional inspection accuracy—especially for reflective or high-precision surfaces. Additionally, the design enhances depth of field and telecentricity, making it ideal for applications requiring consistent magnification and reliable edge detection.

Typical Applications

• LCD / OLED panel inspection: scratch, mura, contamination, edge defect detection
• Touch Panel (TP) inspection: coating uniformity, micro defects, boundary inspection
• LTO / FPC circuit inspection: line break, short circuit, overlay misalignment
• PCB circuit AOI: trace inspection, solder mask edge detection, micro line measurement
• Food & pharmaceutical appearance inspection: packaging sealing, label alignment, contamination/foreign object detection
• Precision parts inspection: stamped parts, machined components, connector pins, micro holes
