Product Overview

NIR-enhanced compact telephoto lens for superior day/night imaging without IR cut-off, perfect for low-light conditions.

The Sunex DSL208A-NIR-F2.0 is a compact telephoto lens specifically designed for day/night imaging applications that require enhanced performance in the near-infrared (NIR) spectrum. Unlike standard lenses, this model does not feature an IR cut-off filter, allowing it to capture more details in low-light or night conditions, making it highly suitable for surveillance and industrial monitoring. The lens has an effective focal length (EFL) of 15.8 mm, an F/2.0 aperture for optimized light intake, and a 6 mm image circle, all housed within a durable metal barrel with an M12x0.5 mount. This telephoto lens offers exceptional clarity and detail in both visible and NIR spectrums, making it an excellent choice for applications that demand precision under varying light conditions.
