DSL182B-NIR-F2.2: Superfisheye Lens for Low-Light Vision Applications

The DSL182B-NIR-F2.2 lens is a superfisheye lens specifically engineered for enhanced performance in low-light and near-infrared (NIR) applications. With an effective focal length (EFL) of 1.39mm, a 194-degree horizontal field of view (HFOV), and an aperture of F/2.2, this lens is optimized for high-definition (HD) imaging with excellent light-gathering capability. Designed with a tailored distortion to minimize optical aberrations, the DSL182B-NIR-F2.2 is ideal for applications in security cameras, surveillance systems, automotive vision, and robotics where infrared sensitivity is crucial.

This lens is equipped with a sealed first element that enhances its durability and prevents damage from dust, moisture, and environmental factors. The absence of an IR cutoff filter makes it particularly suitable for NIR imaging tasks, allowing it to capture light beyond the visible spectrum, making it a top choice for night vision applications. The DSL182B-NIR-F2.2 lens is compatible with sensors up to 1/3 inch in size, providing flexibility for a wide range of camera models and embedded systems. Its image circle measures 5.4mm, ensuring full sensor coverage and high-resolution image capture.

Technical Specifications:

• Effective Focal Length (EFL): 1.39mm
• Aperture: F/2.2
• Horizontal Field of View (HFOV): 194 degrees
• Sensor Compatibility: Up to 1/3 inch
• Image Circle: 5.4mm
