KEYENCE CA-LH25G Vibration Resistant Vision Lens

The KEYENCE CA-LH25G is a 25 mm focal-length, vibration-resistant lens designed for Keyence CA-L vision systems, delivering high-resolution, low-distortion imaging in demanding industrial environments. It features an adjustable aperture from F1.4 to F16, a C-mount interface, and compatibility with 2/3-inch image sensors, plus a 27 mm filter diameter for protective or color-enhancing accessories. Key specifications include about 100 cycles/mm center resolution and roughly 80 cycles/mm toward the periphery, with a lens distortion of approximately -0.04% at the center, supporting precise measurement and inspection tasks. The lens weighs around 89 g and is designed for operation in ambient conditions from 0 to 50 °C and 35–80% relative humidity (non-condensing). Its design emphasizes stability under vibration, making it suitable for inline machine-vision inspections on lines with mechanical movement or equipment vibration. Typical applications include small-part inspection, assembly verification, and other precision gauging tasks where consistent image quality is critical for reliable results. The CA-LH25G aligns with Keyence’s CA-L lens family, offering a compact, high-performance option when vibration resistance is essential to maintain sharp focus and repeatable measurements.
