Product Overview
High-resolution wide-angle lens without IR cut filter, optimized for NIR imaging.
The DSL311A-NIR-F2.8 from Sunex is a wide-angle lens optimized for near-infrared (NIR) imaging applications. This lens, designed without an IR cut-off filter, enhances sensitivity in the near-infrared spectrum, making it ideal for low-light environments such as night vision and security systems. It features a 2.5mm effective focal length (EFL) and an F/2.8 aperture, supporting sensors up to 1/3 inch with a 6mm image circle. The aluminum barrel with M12x0.5 threading ensures durability, while the 1.3MP resolution offers clear, high-quality images in NIR-dependent systems.
