Product Overview

The Computar TG3Z2910FCS-IR is a 1/3" CS-mount varifocal lens designed for day/night security surveillance applications. With a 2.9-8.2mm focal length range, fast F1.0 aperture, and IR-compatible optical design, it supports flexible wide-angle monitoring and clear imaging in low-light conditions.

Key Configuration

Model: Computar TG3Z2910FCS-IR; lens format: 1/3"; focal length: 2.9-8.2mm; aperture: F1.0; max aperture ratio: 1:1.0; mount: CS-mount; controls: manual iris and focus; max image format: 4.8mm x 3.6mm.

Key Features

• 2.9-8.2mm varifocal range supports wide-area coverage and tighter scene framing.
• F1.0 aperture helps deliver bright images in low-light surveillance environments.
• Manual iris and focus controls allow precise setup for the target scene.
• IR-compatible design supports day/night camera operation.
• CS-mount construction provides compatibility with supported 1/3" camera systems.

Technical Context

The lens provides a diagonal angle of view from 125.6° to 44.7°, a horizontal angle of view from 95.0° to 35.6°, and a vertical angle of view from 69.0° to 26.7°. This makes it suitable for broad surveillance coverage while still allowing narrower framing when needed.

Installation Notes

Use with compatible 1/3" CS-mount cameras. During installation, adjust focal length, iris, and focus for the required field of view, then verify image sharpness under both daytime and low-light operating conditions.
