The Keyence CA-LH35 High-resolution Low-distortion Lens is a precision-engineered optical solution designed for machine vision, measurement, and inspection systems that require both clarity and accuracy. With a 35 mm focal length, the lens delivers detailed imaging, making it ideal for applications where medium-distance observation is critical, such as component inspection, defect detection, or dimensional measurement. The design focuses on achieving a balance between magnification and field of view, enabling users to capture high-quality images without sacrificing operational efficiency.

One of the lens’s defining characteristics is its wide aperture range of F2.0 to F16. This flexibility allows users to adapt the lens to different lighting conditions and depth-of-field requirements. For example, when maximum brightness and sharpness are needed in low-light conditions, the F2.0 aperture ensures ample light transmission. Conversely, when precise focus across multiple layers of a subject is required, stopping down to F16 delivers extended depth of field. This adaptability makes the CA-LH35 well-suited for diverse industrial environments where lighting and imaging conditions often vary.

The minimum working distance of 0.2 meters (0.7 feet) enhances versatility by enabling close-range imaging while still maintaining exceptional clarity. This feature is particularly beneficial in compact setups, automated assembly lines, or quality control stations where space is limited. Combined with the lens’s ability to deliver low distortion, it ensures that measurements and inspections remain accurate even at shorter working distances.

Engineered with a C-mount design, the CA-LH35 integrates seamlessly with a wide range of Keyence and third-party industrial cameras. The C-mount standard has long been the preferred choice in machine vision due to its stability, compact form factor, and ease of installation. Additionally, the lens supports a 27.0 mm filter size (P0.5 thread pitch), allowing users to incorporate optical filters to enhance imaging performance. This capability enables greater control over lighting conditions, glare reduction, or wavelength-specific inspections depending on the application.

A major strength of the CA-LH35 lies in its low-distortion optical construction. In machine vision and inspection applications, image distortion can lead to inaccurate measurements or missed defects. By minimizing distortion across the field of view, the lens ensures that image data remains consistent and precise. This reliability is especially important in advanced automation environments where repeatability and accuracy directly impact productivity and quality control.

In summary, the Keyence CA-LH35 is a robust and versatile lens designed for industrial imaging applications requiring precision, flexibility, and durability. Its high-resolution optics, wide aperture range, and distortion control provide engineers and operators with a dependable tool for enhancing inspection accuracy and operational efficiency. Whether used in automated quality inspection, machine vision, or measurement systems, the CA-LH35 delivers reliable performance, making it a valuable asset in any high-precision imaging setup.
