HG3Z1014FCS: CBC-Computar 1/2" 10-30mm f1.4 A/I (CS-Mount)
The Computar HG3Z1014FCS is a high-performance 1/2" format varifocal lens designed for demanding machine vision, surveillance, and industrial imaging applications where flexibility and consistent image quality are critical. Featuring a 10–30mm focal range and a fast f/1.4 aperture, this lens enables precise field-of-view adjustment while maintaining excellent low-light performance and sharp image reproduction across the entire zoom range.
Built with DC auto iris (A/I) control, the HG3Z1014FCS automatically adjusts to changing lighting conditions, ensuring stable brightness and optimized exposure in dynamic environments. This makes it especially well-suited for outdoor surveillance, factory automation, and applications with fluctuating illumination.
Engineered with all-glass optics and a rugged metal housing, the lens delivers long-term durability and consistent optical performance. The inclusion of locking set screws ensures that focus and zoom settings remain fixed even in high-vibration installations, reducing maintenance and recalibration needs.
By combining multiple focal lengths into a single lens, the HG3Z1014FCS helps integrators reduce inventory complexity and installation time—eliminating the trial-and-error associated with fixed focal lenses.
