CH668A 1.1" 50mm 25MP Machine Vision Lens

The CH668A is an industrial fixed-focus lens designed for high-precision long-distance detection. With its 50mm focal length and 25-megapixel high-resolution performance, it has become an ideal solution for long-distance imaging in the semiconductor, precision manufacturing and automation fields.

CH668A has the following core highlights:

High-resolution telephoto capability: The lens is equipped with a 25-megapixel optical system and a 50mm focal length, which can clearly capture tiny targets in medium and long-distance scenes, such as semiconductor wafer inspection and precision component measurement, ensuring that image details are clear and edges are sharp without blur.

Precise field of view focus: The narrow horizontal field of view angle of 16.1° effectively compresses the field of view, focuses on the core area of ​​the target, reduces background interference, and improves detection accuracy and efficiency.

Large aperture dynamic depth of field control: The adjustable aperture design from F2.8 to F16 can adapt to complex light environments: increase the amount of light entering under low light conditions to ensure imaging brightness; the large aperture mode supports shallow depth of field and accurately focuses on key areas; the small aperture mode expands the depth of field, taking into account panoramic clarity and detail resolution.

Multi-target surface high compatibility: Based on the optimization of the 1.1-inch target surface, it is backward compatible with mainstream sensor chips such as 1-inch and 2/3-inch, and is adapted to different camera platforms. Combined with optical aberration correction technology, the distortion is strictly controlled within the full field of view, and the imaging consistency is excellent.

Compact C-mount and flexible expansion: Standard C-mount design, seamless connection with mainstream industrial camera brands, easy installation. Standard M40.5×P0.5 filter interface, supports customized optical accessories (such as infrared cutoff, neutral density filter), and can easily cope with complex working conditions such as strong light and stray light.

All-glass lens: All-glass lens with high light transmittance and low dispersion characteristics ensures stable and reliable image quality, and can provide high-quality imaging effects even in low light conditions.

With its 50mm focal length and 25 million pixels, the CH668A industrial lens is suitable for a variety of specific industrial scenarios:

1. Aerospace parts inspection

The parts in the aerospace field have complex structures, extremely high precision requirements, and the detection distance is often far. The 50mm focal length of the CH668A machine vision lens enables it to clearly observe parts at a long distance. The 25 million pixels can accurately capture problems such as tiny cracks and dimensional deviations on the surface of parts. The 16.1° horizontal field of view can focus on key areas, helping inspectors to promptly discover potential defects and ensure the safety and reliability of aerospace products.

2. Solar photovoltaic panel inspection

During the production process of solar photovoltaic panels, scratches, stains, and cell welding quality on the surface of photovoltaic panels need to be inspected. The CH668A machine vision lens can be installed above the production line, and its focal length and field of view advantages can be used to perform long-distance, high-precision imaging inspections on photovoltaic panels on the conveyor belt. By flexibly adjusting the aperture, the details of the photovoltaic panels can be clearly presented under different lighting conditions, ensuring that product quality meets standards and improving the power generation efficiency and service life of photovoltaic panels.

3. PCB circuit board welding quality inspection

As electronic products continue to develop towards miniaturization and precision, the components on PCB circuit boards are getting smaller and smaller, and the welding precision requirements are getting higher and higher. The combination of high pixels and 50mm focal length of CH668A machine vision lens can clearly present the shape, position and other information of tiny solder joints on the circuit board. The characteristics of adapting to a variety of chips enable it to cooperate with industrial cameras of different precisions to achieve high-precision detection of PCB circuit board welding quality, timely discover problems such as cold soldering and short circuits, and ensure the performance and stability of electronic products.

4. Textile fabric defect detection

In textile production, fabric defects are of various types and in various forms. CH668A machine vision lens is installed at the end of the textile production line. It uses a large field of view and high pixels to quickly scan the surface of the fabric, and can clearly identify defects such as broken yarn, stains, and holes on the fabric. By installing filters to optimize the imaging effect, defects can be accurately detected even in complex lighting environments, helping companies improve fabric quality and reduce defective rates.

5. Internal inspection of automobile engines

The internal structure of automobile engines is precise, and it is difficult to detect its components. The CH668A machine vision lens can be used with endoscopes and other equipment to reach into the engine for inspection. With a focal length of 50mm and a horizontal field of view of 16.1°, it can clearly capture the wear and cracks of components such as pistons and valves in a limited space. The 25 million pixels ensure the clarity of the image, providing a reliable basis for engine repair and maintenance, and extending the service life of the engine.
