Amid the Industry 4.0 revolution, the manufacturing sector’s demands for inspection efficiency and accuracy have reached near-physical limits. Traditional fixed-focus lenses, unable to flexibly adapt to inspection needs across multiple sizes, have gradually become a bottleneck in production line efficiency. Through innovative optical design and intelligent control technology, POMEAS ZOOM LENSES offer a “one-lens-multiple-uses” solution that delivers an exponential increase in inspection efficiency for industries such as semiconductors, 3C electronics, and automotive manufacturing, redefining the standards of “speed and precision” in industrial inspection.

Technical Core: How Can Continuous Zoom Overcome Physical Limitations?

The core advantage of the POMEAS ZOOM LENS lies in its continuously adjustable focal length technology. Through a precision-engineered lens group movement mechanism, the lens can be adjusted steplessly within a zoom range of 0.68X to 5X, covering inspection needs ranging from macro-level overviews to micro-level details. For example, when inspecting a smartphone screen, the lens can first use a 0.7X magnification to quickly scan the entire panel for scratches and color aberrations, then instantly switch to 4.5X magnification to focus on defects at the pixel level—all without changing lenses or moving the workpiece.

The Ultimate Pursuit of Optical Performance:

• Telecentric optical design: Eliminates perspective distortion, ensuring consistent image scale for objects at different distances and preventing measurement errors caused by “near objects appearing larger than far objects”; particularly suitable for dimensional inspection of precision components;

• Ultra-low distortion control: Utilizing aspheric lenses and high-precision assembly processes, distortion is reduced to within 0.02%. Even when inspecting circular objects (such as bearings and gears), edge straightness is maintained, providing reliable data for AI defect recognition;

• High-resolution imaging: Supports 4K-class sensors; combined with a large numerical aperture (N.A.) design, it can clearly resolve surface textures at the 0.1μm level, meeting ultra-precision requirements such as photoresist overlay inspection in semiconductor manufacturing and micro-well analysis in biochips.

Intelligent Control: Enabling the lens to “actively adapt” to the detected scene

The intelligence of POMEAS ZOOM LENSES is reflected in their seamless integration with the industrial ecosystem:

• Motorized Zoom Synchronization: By interfacing with a PLC or robot controller via RS232/USB, the lens automatically adjusts its focal length in real time based on the workpiece’s position. For example, during the inspection of automotive engine blocks, as the robotic arm moves the workpiece, the lens synchronizes its zoom to maintain a clear image, preventing inspection failures caused by vibration or changes in distance;

• Parameter Memory and One-Touch Switching: The system can store parameters such as focal length, aperture, and gain for different inspection tasks. Operators can quickly recall preset programs via the touchscreen or by scanning a QR code, reducing manual debugging time;

•  

  Remote Cluster Management: Supports centralized control of multiple devices over a network. Administrators can monitor lens status and adjust parameters in real time from the control room, and even perform OTA firmware updates, significantly improving equipment maintenance efficiency.

   

POMEAS ZOOM LENSES have become deeply integrated into key processes in the manufacturing industry:
 

• Semiconductor Industry: In wafer inspection, the ZOOM LENS covers inspection needs ranging from the entire wafer to individual chips with a 10x zoom ratio. Combined with AI algorithms, it enables real-time defect classification, thereby improving yield rates;
   
• 3C Electronics: When inspecting for microscopic scratches on smartphone frames, the lens uses ultra-fast 0.3-second zooming and High Dynamic Range (HDR) imaging to accurately identify defects as small as 0.02 mm in length, thereby reducing rework costs;
   
• Automotive Industry: When measuring the radial thickness of engine piston rings, the lens, combined with a laser displacement sensor, completes multi-point measurements within 0.1 seconds, with a data repeatability error of less than 1 μm, supporting large-scale customized production.
