Product Summary

Narrow field of view lens with integrated 680nm IR cut filter, optimized for high-resolution applications.

The DSL331A-680-F2.0 from Sunex is a high-resolution glass lens, designed for applications requiring a narrow field of view (FOV). With an effective focal length (EFL) of 19.8mm and an F/2.0 aperture, this lens is suitable for sensor formats up to 1/1.55". The integrated IR cut filter at 680nm ensures sharp, clear images by minimizing infrared light interference. Its M16x0.5mm metal barrel provides robust construction, making it suitable for demanding industrial and surveillance applications. The lens supports resolutions up to 6MP, making it ideal for machine vision, inspection, and other high-precision tasks requiring a narrow FOV and high image clarity.
