In the advancement of Industry 4.0 and Smart Manufacturing, precise visual guidance has become crucial for fluid control equipment to achieve high-quality operations. Anda Intelligent Equipment Co., Ltd. (Stock Code: 688125), a company specializing in the R&D, production, and sales of fluid control equipment, plasma cleaning equipment, and intelligent manufacturing solutions, deeply understands the critical role of vision systems in precision fluid control. This is particularly true for applications such as dispensing positioning, coating quality inspection, and bead pattern analysis. It is precisely for this reason that the company has strategically expanded into key machine vision components, launching high-performance industrial liquid telecentric lenses to empower smart manufacturing with comprehensive technological capabilities.



1/Understanding Telecentric Lenses


Conventional industrial FA lenses struggle to meet the imaging challenges of high-precision measurement due to limitations in their depth of field and perspective errors. Driven by a deep understanding of these industry pain points, Anda Smart has introduced its independently developed series of telecentric lenses.

Telecentric lenses employ a unique optical design that ensures the principal rays travel parallel to the optical axis. This effectively eliminates perspective error (the "larger-nearer, smaller-farther" effect) and maintains a consistent image magnification regardless of the object's distance. These characteristics make them particularly suitable for high-precision applications such as dimensional measurement, appearance inspection, and positioning recognition.

Telecentric lenses offer the following key features:

  • Constant Magnification: Unaffected by variations in the object distance.

  • Large Depth of Field: Accommodates the inspection of objects with varying heights.

  • Extremely Low Distortion (<0.05%): Guarantees measurement accuracy.

  • Uniform Image Illumination: Ensures consistent sharpness and clarity across the entire image.

2/Anda Liquid Telecentric Lens


Anda Smart has innovatively integrated liquid lens technology into a telecentric optical design, launching its Liquid Dual Telecentric Lens Series. This represents a groundbreaking solution for the fluid control industry.

Based on the electrowetting effect, the product applies a controlled voltage to the interface between two immiscible liquids, altering the droplet curvature to achieve millisecond-level dynamic focus adjustment. This innovation completely eliminates the need for traditional mechanical movement.

Its features include:

  • Dynamic Focusing: Millisecond-level response with focus time <30 ms, effectively solving imaging challenges for objects with height variations.

  • No Mechanical Wear: Longer service life and virtually maintenance-free.

  • Extra-Large Depth of Field: Depth of field can reach tens of millimeters, easily enabling fast and clear imaging of objects with significant height differences.

  • High-Precision Measurement: Possesses all the advantages of a standard telecentric lens.

  • Self-Developed Driver Software: Supports flexible system integration and secondary development.

  • Comprehensive Specifications: Magnification options include 0.3×, 0.5×, 1×, and 4×, with support for custom requirements.
