Product Overview

Wide FOV lens without IR cut-off, optimized for low-light and NIR imaging on 1/1.55” sensors.

The DSL333A-NIR-F2.8 is a high-performance wide FOV lens designed for applications requiring broad light spectrum capture, including near-infrared (NIR) imaging. With an effective focal length (EFL) of 4.3mm and an F/2.8 aperture, this lens is optimized for use with 1/1.55" sensors, supporting resolutions up to 6MP. The absence of an IR cut filter allows for enhanced light sensitivity, making this lens particularly useful for low-light and NIR applications. The durable metal barrel with M14x0.5 threading ensures stability and reliability in industrial, machine vision, and security applications.
