Computar - CMP-TG2Z1816FCS - 1/3-inch 1.8-3.6mm F1.6 Auto Iris

Product Overview

The Computar TG2Z1816FCS is a 1/3" CS-mount varifocal lens designed for extreme wide-angle surveillance and imaging applications. With a 1.8-3.6mm focal length range, DC auto iris control, and durable all-glass optical construction, it supports broad scene coverage in indoor or outdoor environments with changing light conditions.

Key Configuration

Model: Computar TG2Z1816FCS; lens format: 1/3"; focal length: 1.8-3.6mm; iris range: F1.6-F360; max aperture ratio: 1:1.6; iris type: DC auto iris; mount: CS-mount; max image format: 4.8mm x 3.6mm.

Key Features

• 1.8-3.6mm varifocal range supports extreme wide-angle scene coverage.
• DC auto iris adjusts exposure automatically in areas with large lighting variation.
• F1.6 aperture helps improve image brightness in lower-light scenes.
• All-glass optics, locking set screws, and metal barrel support durable operation.
• Pre-wired connector and no-amplifier design support straightforward camera integration.

Technical Context

When used on a 1/3" camera, the lens provides a horizontal angle of view from 144.2° to 79.4°, a vertical angle of view from 109.4° to 59.6°, and a diagonal angle of view from 173.8° to 99.0°. This makes it suitable for monitoring wide spaces where reducing blind spots is important.

Installation Notes

Use with compatible 1/3" CS-mount cameras that support DC auto iris operation. After mounting, adjust focal length and focus for the required coverage area, then verify exposure response across the expected lighting range.
