How to Implement the Efficient Detection of the Surface

In modern industrial manufacturing and quality control processes, the accurate measurement and inspection of surfaces play a crucial role. When dealing with a large number of small parts that require measurement, traditional optical measurement methods often encounter challenges. For instance, a small Field of View (FOV) lens can only capture a limited number of parts in a single shot, which significantly increases the measurement time and complexity. On the other hand, a large FOV lens might seem like an appealing solution to expedite the measurement of multiple small parts simultaneously. However, it often brings about the issue of blurred imaging. This blurred imaging can be attributed to various optical aberrations and limitations that are exacerbated when attempting to cover a wider area.

Let us consider a practical example in a precision engineering workshop. There are thousands of minuscule components, each with critical surface features and tight tolerances. The use of a small FOV lens would require the operator to painstakingly move the lens millimeter by millimeter, capturing a few parts at a time and then repeating the process over again. This could potentially take hours or even days to complete the measurement of the entire batch. On the other hand, if a large FOV lens is used, the resulting images might be so blurry that it becomes a guessing game to determine the actual dimensions and surface characteristics of the parts. This not only wastes valuable time but also poses a significant risk of producing defective products due to inaccurate measurements.

Fortunately, there is a revolutionary solution that has emerged to address these challenges - Basson’s large FOV bi-telecentric lens. This optical device represents a significant leap forward in the field of surface detection technology. The Basson lens features an impressive FOV of 155mm, which allows for a substantially larger area to be imaged in a single shot compared to traditional lenses. This means that a greater number of small parts can be encompassed within the field of view, enabling a more efficient and comprehensive measurement process. For instance, in a production line where previously it might have taken an inordinate amount of time to measure a large quantity of small parts using conventional lens setups, the Basson lens can potentially reduce the measurement time.

By being able to capture more parts in one go, it streamlines the overall measurement workflow and minimizes the need for excessive repositioning and multiple captures. One of the most remarkable aspects of the Basson lens is its micron-level accuracy. In industries such as microelectronics, medical device manufacturing, and aerospace, where even the slightest deviation in surface dimensions can have catastrophic consequences, this level of precision is non-negotiable. The lens is engineered to resolve details with an accuracy that is measured in microns, ensuring that the tiniest surface irregularities, scratches, or dimensional variations are accurately detected and quantified. This high level of accuracy is achieved through a combination of advanced optical design, precise manufacturing techniques, and meticulous quality control.

The bi-telecentric design of the Basson lens is another key factor that sets it apart from conventional optics. Telecentricity, which refers to the alignment of the chief rays of light parallel to the optical axis, is maintained at an extremely low level of less than 0.05° in this lens. This has profound implications for the measurement process. With such low telecentricity, the lens effectively minimizes perspective errors that are commonly associated with non-telecentric lenses. In a non-telecentric lens, as the object moves within the FOV, the magnification and perspective can change, leading to inaccurate measurements. However, the Basson lens ensures that the measurement remains consistent and accurate regardless of the position of the object within the FOV. This is especially crucial when measuring small parts with complex geometries or when multiple parts need to be measured with the same level of precision. In addition to the low telecentricity, the Basson lens also exhibits a remarkably low distortion rate of less than 0.05%. Distortion can cause significant deformations in the captured images, which can lead to inaccurate measurements of geometric shapes and dimensions. In applications where the shape and size of the objects need to be precisely determined, such as in the automotive and mechanical engineering industries, low distortion is of paramount importance. The Basson lens’s minimal distortion rate guarantees that the images obtained are a faithful representation of the actual objects, allowing for accurate analysis and measurement of surface parameters.

If the measurement requirements extend beyond a large number of small parts to encompass even more extensive and larger objects, Basson offers a range of high-precision lenses with even larger FOVs. These lenses are designed to meet the diverse needs of different industries and applications. For example, in the manufacturing of large-scale industrial machinery or in the inspection of architectural structures, these lenses can provide a comprehensive view of the surfaces while maintaining the high level of accuracy and image quality required. The ability to offer lenses with varying FOVs and precision levels gives Basson a competitive edge in the market and enables them to cater to a wide spectrum of customers. The manufacturing process of the Basson large FOV bi-telecentric lens is a complex and highly technical affair. It begins with the careful selection of optical materials that possess the ideal refractive index and dispersion properties. These materials are sourced from reliable suppliers and undergo rigorous quality checks to ensure their suitability for the lens manufacturing process. The lens elements are then fabricated using advanced machining and polishing techniques. Precision grinding and polishing are carried out to achieve the required surface curvatures, with tolerances maintained at the micron level.

Once the individual lens elements are fabricated, they are assembled in a cleanroom environment. The cleanroom is maintained at a specific temperature, humidity, and particulate level to prevent any contamination that could affect the optical performance of the lens. Skilled technicians use specialized alignment and calibration tools to assemble the lens elements with utmost precision. The alignment process is critical as it determines the overall optical performance of the lens. Any misalignment can lead to a degradation in image quality and accuracy. After assembly, the lens undergoes a comprehensive series of tests to verify its optical properties, including telecentricity, distortion, and accuracy. These tests are carried out using highly accurate measurement equipment and reference standards.

In addition to the exceptional optical performance of the lens itself, Basson also provides a comprehensive suite of support services to its customers. Technical consultation is a key aspect of this support. Basson’s team of experienced optical engineers and technicians are available to assist customers in selecting the most appropriate lens for their specific application. They take into account factors such as the size and shape of the objects to be measured, the required level of accuracy, and the environmental conditions in which the lens will be used. This personalized consultation helps customers make informed decisions and ensures that they get the best performance out of the Basson lens.

Calibration services are another vital component of Basson’s customer support. Over time, due to factors such as temperature changes, mechanical stress, or normal wear and tear, the optical properties of the lens may change slightly. To maintain the accuracy and reliability of the lens, Basson offers regular calibration services. These services involve using calibrated reference objects and advanced measurement techniques to adjust the lens parameters and bring them back to their original specifications. By providing calibration services, Basson ensures that the lens continues to perform at its peak level throughout its operational life.

Basson is also committed to continuous R&D in the field of optical technology. The company invests significant resources in exploring new materials, designs, and manufacturing processes to improve the performance of its lenses. This includes efforts to increase the FOV while improving accuracy, reducing the size and weight of the lenses for more convenient integration into different measurement systems, and enhancing the lens’s resistance to environmental factors such as temperature fluctuations, humidity, and vibration.
