Product Overview
Sunex M12 Fixed Focal Lens, EFL 1.39mm: A fixed focal lens with an EFL of 1.39mm, aperture F2.2, and supports up to 1.3 Megapixels for image circles up to 5.4mm. No IR-cut filter is included.
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
- No IR-cut Filter (for NIR imaging)
- Aluminum barrel with M12x0.5 threading
- Sealed first element for environmental protection
The DSL182B-NIR-F2.2 is built for robust performance with an aluminum barrel that provides mechanical strength and longevity in industrial settings. Its fixed focal design ensures reliable performance across various environments, and the threaded M12x0.5 mount makes installation easy in a wide range of vision systems. The lack of an IR-cut filter allows for maximum infrared light capture, making it highly efficient in capturing images in complete darkness or low-light scenarios.
If you're in need of a high-performance lens that supports NIR imaging and delivers superior image clarity in both day and night environments, the DSL182B-NIR-F2.2 is the perfect choice. This lens is especially useful in security applications where clear, accurate footage is essential, even in low-light conditions. Whether it’s used in autonomous vehicles, industrial robots, or smart surveillance systems, this lens provides the sharp, clear visuals needed for precise object detection and tracking.
For users requiring a versatile, highly-durable lens solution capable of handling both day and night operations, the DSL182B-NIR-F2.2 is an excellent addition to any vision system. It’s also compatible with the CTM168 adapter, offering more options for customization in your imaging setup.
