New high-performance varifocal lens suitable for industrial cameras.
VT4Z1450 Series
High-performance zoom lens with visible light support up to 940nm and aspherical design.
The VT4Z1450 series is an industrial varifocal lens compatible with 1-inch 8M cameras. Its Day & Night design corrects chromatic aberration across a wide spectrum from visible light to near-infrared light (940nm), achieving stable high-definition images regardless of day or night. Additionally, it features a "no F drop design," which maintains a constant F-number throughout the zoom range, allowing for observation while preserving brightness. The aspherical design minimizes focus shift due to temperature changes, ensuring stable focus performance even in environments with significant fluctuations. Furthermore, its metal housing provides excellent environmental resistance, making it suitable for high-temperature applications such as furnace monitoring. With the addition of close-up lenses, it also supports close-up photography, flexibly accommodating a variety of inspection and monitoring applications.

Applications/Examples of results
1. Monitoring of furnace and high-temperature equipment Monitoring the condition inside blast furnaces, glass melting furnaces, and kilns. With a metal housing and an athermal design, it minimizes focus shift even in high-temperature environments, enabling stable monitoring for extended periods. 2. Monitoring of outdoor equipment at night (infrastructure and plants) 24-hour monitoring of power plants, chemical plants, and port facilities. By supporting visible light to 940nm, it achieves stable imaging during the day in color and at night with near-infrared lighting. 3. Visual inspection of production lines Visual inspection of product appearance and presence determination on conveyor lines. With a constant F-value across the zoom range, it can operate without changing lighting conditions when adjusting magnification. 4. Embedded monitoring of semiconductor and electronic components Process verification within mounting and inspection equipment. High resolution (1 inch 8MP compatible) allows for clear observation of fine structures. 5. Close inspection (using close-up lenses) Close observation for tiny scratches, foreign objects, and print verification. By attaching a close-up lens, it can handle a wide range from distant to close-up observations with a single lens.
