Product Overview

Low-profile megapixel wide-angle lens optimized for NIR applications with no IR cut filter.

The DSL235D-NIR-F3.2 is a low-profile wide-angle lens from Sunex, designed for high-performance imaging with 1/3" sensors, featuring no IR cut-off filter for full-spectrum or near-infrared (NIR) applications. With an effective focal length (EFL) of 3.02mm and an F/3.2 aperture, this lens provides excellent resolution and clarity for applications up to 1.3 MP. The absence of an IR filter makes it ideal for night vision, NIR imaging, and low-light conditions. Its compact M8x0.35 metal barrel construction ensures durability, and the included lens cap with an o-ring gland offers added protection. The 6mm image circle fits perfectly for a variety of industrial and surveillance imaging systems requiring full-spectrum sensitivity.
