TCCX series is a range of lenses designed for measurement and defect detection on flat surfaces. They feature the same magnifications and working distance of TCLWD series while adding integrated coaxial light.

Such lighting configuration is required to homogeneously illuminate uneven surfaces and detect small surface defects such as scratches or grooves, finding application in many industries, from the electronics and semiconductor industries to the glass and metal fabrication industries.

All these lenses operate at a working distance of 132 mm while their large numerical aperture enables the superior resolution needed for small pixel cameras, matching and even exceeding the industrial requirements of on- and offline applications.

The built-in LED source, equipped with advanced electronics, provides excellent illumination stability and homogeneity, key factors for the reliability of any machine vision system.

The unique optical design minimizes the internal reflection issues of conventional coaxial illumination systems: this makes TCCX lenses the perfect choice especially when inspecting highly reflective flat surfaces (approx. > 30% reflectance).

Typical application include recognition of silicon wafers pattern and inspection of LCD displays, polished metal surfaces, plastic and glass panels, and many other.

Note: for opaque samples (reflectance <30%) please refer to TCCXQ Series

TCEL series by Opto Engineering® features a perfect combination of telecentric optics and liquid lenses technology allowing to significantly increase the depth of field (DOF). This is particularly important for small fields of view due to the proportionality of the DOF with the magnification.

Thanks to their optical design, TCEL lenses ensure excellent optical performances both in terms of telecentricity and especially distortion throughout the entire operating range. This makes them a perfect choice for many inspection and measurement applications ranging from the electronics and semiconductors industry, to the automotive sector.

The built-in, electronically controlled Optotune liquid lenses enable to precisely tune the optical power of telecentric lenses adjusting the focus: this adjustment can be extremely fast with response times in the order of few milliseconds. The driver comes as a compact USB-powered current source with free software and can be used as a stand-alone solution or integrated into OEM designs. Communication follows an open simple serial protocol, which can be implemented in any programming language on Windows or Linux (C#, Labview and Python source code available).

Didn’t find what you were looking for?

Don’t worry! We can integrate liquid lenses with many other models including those with coaxial illumination.

TCLWD3M series is a range of high resolution telecentric lenses specifically designed for electronic and semiconductor Automated Optical Inspection (AOI) and tool pre-setting machines. The long working distance allows for extra space, which is essential if you need to install illumination, pick-up tools or provide the necessary separation from hazardous production processes.
TCLWD3M lenses have been optimized to match up to the new 1.1” Sony sensor in order to deliver high resolution and superb image quality.

In addition to the long working distance, TCLWD3M optics deliver a numerical aperture large enough to take advantage of high resolution / small pixel size cameras, making these lenses a perfect match for general-purpose 2D measurement systems.
