Elevate Your Imaging with the Kowa LM4NCR 3.5 mm Fixed Focal Lens
The Kowa LM4NCR 1/2" 3.5 mm Fixed Focal Manual Iris Lens stands out in the realm of industrial and commercial applications, particularly in machine vision systems. Designed for high-performance imaging, this lens excels in both low light and bright conditions, thanks to its impressive aperture range of F1.4 to close. With a fixed focal length of 3.5 mm, the LM4NCR offers a wide angle of view (103.6° horizontal and 76.6° vertical) that captures expansive scenes with remarkable clarity.
This lens is particularly beneficial in settings that require precise imaging and consistency. It features a manual iris that allows users to adjust the aperture to their specific requirements, ensuring optimal exposure under varying lighting conditions. The fixed focal point ensures that the focus remains constant throughout its lifespan, eliminating the need for constant adjustments. This reliability is crucial for applications like quality control, robotics, and surveillance, where consistent imaging quality is paramount.
The Kowa LM4NCR lens is a solid choice for industrial environments, boasting durability with a temperature range of -10°C to +45°C and storage capabilities from -40°C to +60°C. Its compact design (weighing only 56g) and C-mount compatibility make it easy to integrate into existing systems, providing users with high-resolution images (100 lp/mm in the center and 40 lp/mm in the corners) and minimal optical distortion.
