Computar - TG10Z0513AFCS - Video Auto Iris CS-Mount, 5-50mm

Product Overview

The Computar TG10Z0513AFCS is a high-performance 10x zoom CS-mount lens featuring a versatile 5-50mm focal length and a fast F1.3 maximum aperture. Optimized for 1/3" format sensors, this lens utilizes a motorized video auto iris for dynamic light management and offers manual controls for both focus and zoom adjustment. It operates on a DC8.5V–16V power range and includes a light-weighting adjustment feature, allowing users to switch between average and peak modes for customized exposure control in varying lighting conditions.

Key Features

The features video auto iris control powered by a DC8.5V-16V supply, operating with a low current draw of less than 40mA. It offers adjustable light weighting between average and peak modes, allowing for fine-tuned sensitivity across a 0.5V(p-p) to 1.0V(p-p) video signal range. The system provides an iris accuracy of ±15% with high input impedance and a response time of approximately 2 seconds. For precise framing, the lens is equipped with manual focus and zoom controls to complement its automated exposure capabilities.

Technical Context

The lens maintains a back focal length between 10.5mm and 10.6mm and operates reliably from -20°C to +50°C using a standard video input signal. At its 0.8m minimum object distance, the field of view captures areas ranging from 77.7 x 57 cm at the wide setting down to 7.8 x 6 cm at telephoto. It offers horizontal viewing angles of 51.8° to 5.6° on 1/3" sensors and 39.2° to 4.3° on 1/4" sensors, providing versatile coverage for various monitoring needs.
