High magnification coaxial telecentric lens

High-magnification telecentric lenses, while offering exceptional precision and accuracy, often come with inherent drawbacks related to aperture size and illumination uniformity. One of the most common issues encountered with large-magnification telecentric lenses is the relatively small aperture, which results in reduced light throughput and darker imaging. This limitation can make it difficult to achieve the desired brightness and clarity, particularly when dealing with small fields of view (FOV). Even with the use of a small annular light source, effectively illuminating the top surface of the object under inspection remains a significant challenge. The optical path and alignment of the light source relative to the lens can create non-uniform illumination, leading to potential inconsistencies in measurement and detection accuracy.

To address these challenges, coaxial illumination has been widely adopted in high-magnification optical systems. Coaxial lighting, which involves directing light along the optical axis of the lens, ensures that the object is evenly illuminated from above, reducing shadows and enhancing image contrast. This lighting method provides a significant improvement in surface inspection applications, particularly for highly reflective or low-contrast objects. However, coaxial illumination presents its own set of challenges. One of the primary difficulties associated with coaxial lighting is the adjustment and positioning of the object. When using coaxial light, precise alignment is crucial to ensure uniform illumination across the entire field of view. Even minor deviations in object positioning can result in variations in lighting intensity, making it difficult to achieve consistent inspection results.

To overcome this challenge, the Basson coaxial 10x telecentric lens has been developed. This lens is designed to provide high-quality imaging with uniform illumination and minimal distortion, making it ideal for applications that require accurate measurement and inspection of small objects. The Basson 10x coaxial telecentric lens has a large magnification of 10x, which allows for detailed imaging of small objects. It supports cameras with a 2/3" target surface, which provides a wide FOV and high-resolution imaging. The lens has a resolution of 3.221μm, which is sufficient for most applications that require accurate measurement and inspection of small objects. One of the key features of the Basson 10x coaxial telecentric lens is its coaxial design. The coaxial design allows the illumination and imaging paths to be aligned along the same axis, which provides several advantages over traditional telecentric lenses. First, the coaxial design ensures that the illumination is uniform across the entire FOV, which reduces the amount of glare and reflection in the image. Second, the coaxial design allows for easy adjustment of the object position, as the object can be positioned precisely in the center of the FOV without affecting the illumination.

In addition to its superior illumination performance, the Basson 10x coaxial telecentric lens offers low distortion and high telecentricity. Distortion is a common issue in optical systems, particularly at high magnifications, where even minor aberrations can lead to significant measurement errors. The low distortion characteristics of the Basson lens ensure that the captured image accurately represents the object being inspected, without introducing unwanted geometric distortions. This accuracy is essential in applications where precise measurements are required, such as in metrology and industrial inspection. The high telecentricity of the lens further enhances measurement accuracy by ensuring that the magnification remains constant across different object distances. This feature eliminates perspective errors and ensures that measurements remain consistent and reliable, even when the object is positioned at varying distances from the lens.

In addition to its high-quality imaging and low distortion rate, the Basson 10x coaxial telecentric lens also has a number of other features that make it ideal for a wide range of applications. Another key advantage of the Basson 10x coaxial telecentric lens is its ease of use and integration into existing imaging systems. Traditional coaxial lighting setups often require complex adjustments and precise alignment to achieve optimal illumination. However, the Basson lens is designed to simplify the illumination process, making it easier to achieve consistent and reliable results. The improved design of the coaxial lighting system reduces the need for frequent adjustments, allowing operators to focus on the inspection process rather than on fine-tuning the optical setup. The lens is also durable and reliable, with a rugged construction that can withstand the rigors of industrial use. The Basson coaxial 10x telecentric lens is a powerful and versatile tool for precision manufacturing, semiconductor inspection, and microelectronics. Its high-quality imaging, uniform illumination, low distortion rate, and telecentricity make it ideal for applications that require accurate measurement and inspection of small objects.

Precision manufacturing involves the production of small, complex parts with very tight tolerances. The Basson 10x coaxial telecentric lens can be used to inspect the surface of these parts for defects, such as dimensional errors, surface roughness, and surface finish. The lens’s low distortion rate and telecentricity make it possible to measure the dimensions of the parts accurately, which is essential for ensuring that they meet the required specifications. The Basson 10x coaxial telecentric lens can also be used in microelectronics, which involves the design and production of small electronic components, such as integrated circuits and microchips. The lens can be used to inspect the surface of these components for defects, such as shorts, opens, and missing components. The lens’s high-resolution imaging and uniform illumination make it possible to detect even the smallest defects, which can have a significant impact on the performance of the microelectronic component. In addition to these applications, the Basson 10x coaxial telecentric lens can also be used in a wide range of other fields, such as microscopy, medical imaging, and security.
