DSL183B-650-F2.2: Miniature Tailored Distortion Fisheye Lens with IR Cutoff Filter

The DSL183B-650-F2.2 is a miniature fisheye lens specifically designed for tailored distortion applications. With an effective focal length (EFL) of 1.32mm and a field of view of 180 degrees, this lens is ideal for capturing wide-angle scenes with minimal optical distortion. This makes it suitable for use in applications such as security systems, automotive cameras, and industrial machine vision where a wide field of view and precise image capture are essential. The lens features an F/2.2 aperture, ensuring excellent performance in low-light conditions.

One of the key features of the DSL183B-650-F2.2 is its integrated IR cutoff filter at 650nm, which blocks infrared light to enhance image clarity in daylight applications. This ensures that the lens captures accurate colors and high-quality images, even in high-intensity lighting conditions. The lens is constructed from durable materials, including a metal barrel with M12x0.5 threading, making it suitable for a variety of rugged environments.

Technical Specifications:

  • Effective Focal Length (EFL): 1.32mm
  • Aperture: F/2.2
  • Field of View: 180 degrees
  • Sensor Compatibility: Up to 1/4 inch
  • Image Circle: 5.3mm
  • IR Cutoff Filter at 650nm
  • Metal barrel with M12x0.5 threading
  • Tailored distortion design for enhanced image quality

The lens’s tailored distortion profile minimizes image distortion, ensuring that the lens captures detailed and accurate images across its wide field of view. This feature makes it an excellent choice for machine vision systems, where accuracy is crucial for analysis and decision-making processes. The lens is also compatible with the CMT168 adapter, allowing for easy integration into existing imaging setups.

Designed for high-precision imaging, the DSL183B-650-F2.2 is perfect for use in security, surveillance, and automotive applications where reliable and consistent performance is required. Its rugged design, coupled with advanced optical features such as the IR cutoff filter, makes it a reliable choice for professionals looking for a high-quality, miniature fisheye lens.

If you're looking for a fisheye lens that delivers superior performance with minimal distortion, the DSL183B-650-F2.2 is an ideal solution for your imaging needs.
