Product Summary

High-performance narrow FOV lens without IR cut-off, ideal for 1/1.55″ sensors and precision imaging applications.

The DSL331A-NIR-F2.0 is a high-resolution narrow field of view (FOV) lens designed for precision imaging applications. Featuring an effective focal length (EFL) of 19.8mm and an aperture of F/2.0, this lens is optimized for 1/1.55" sensors, providing crisp, clear images for applications where detail is critical. Unlike versions with IR cut filters, the absence of an IR cut-off filter allows this lens to capture images across a broader spectrum, making it particularly useful for low-light and near-infrared (NIR) imaging tasks. Constructed with a robust M16x0.5mm metal barrel, the lens is designed for durability and precision. This design makes it ideal for industrial, machine vision, and security applications requiring high-resolution imaging.
