Fujinon HF25XA-1F | 1/1.2" 25mm 4D High Resolution Fixed Lens, 5MP, C-Mount, 3.45µm Pixel, Ultra-Low Distortion, Anti-Vibration IEC60068-2-6
The Fujinon HF25XA-1F is a precision 25mm C-mount fixed lens engineered for 4D High Resolution (4DHR) imaging performance, ensuring exceptional edge-to-edge sharpness with minimal resolution degradation even when aperture or working distance changes. Optimized for modern machine vision systems, it is fully compatible with Sony IMX250 CMOS sensors (2/3", 5MP, 3.45µm) and supports sensor formats up to 1/1.2" (4.5µm) for flexible system integration. Delivering an ultra-low TV distortion of -0.07% and a 20.0° × 15.0° angle of view (2/3"), it is ideal for inspection environments requiring precise dimensional accuracy. The fixed F1.6 iris includes interchangeable iris plates for F4.6 and F9.2 to adapt to varying lighting conditions without sacrificing image quality.
Built for reliability in demanding industrial environments, the HF25XA1F features a robust anti-shock and vibration-resistant design compliant with IEC60068-2-6, rated for vibration frequencies of 10–60Hz (0.75mm amplitude) and 60–500Hz (100m/s² acceleration). Its compact Φ34 × 55.4mm housing and lightweight 87g build make it ideal for space-constrained applications. A M25.5 × 0.5 filter thread allows easy optical filtering for wavelength-specific imaging. Whether used in high-speed factory automation, precision inspection, or measurement systems, this lens delivers consistent high-resolution imaging with stable optical performance under continuous vibration and varying environmental conditions.
