DSL184B-NIR-F2.0: Miniature Tailored Distortion Fisheye Lens Without IR Cutoff Filter

The DSL184B-NIR-F2.0 is a miniature fisheye lens that is specifically designed for applications requiring near-infrared (NIR) imaging. The lens has an effective focal length (EFL) of 1.39mm and a wide F/2.0 aperture, which ensures that it can capture clear, high-quality images in low-light conditions. With its tailored distortion feature, the lens is capable of providing a wide 180-degree field of view while minimizing distortion, making it an excellent choice for NIR-sensitive applications such as night vision, surveillance, and robotics.

The absence of an IR cutoff filter allows the DSL184B-NIR-F2.0 to capture both visible and infrared light, making it particularly useful in environments where NIR sensitivity is required. The durable metal barrel with M12x0.5 threading ensures that the lens is rugged enough for industrial and outdoor applications, while the lens's compact design allows for easy integration into a variety of camera systems.

Technical Specifications:

  • Effective Focal Length (EFL): 1.39mm
  • Aperture: F/2.0
  • Field of View: 180 degrees
  • Sensor Compatibility: Up to 1/4 inch
  • Image Circle: 4.8mm
  • No IR Cutoff Filter (optimized for NIR imaging)
  • Durable metal barrel with M12x0.5 threading
  • Tailored distortion for wide-angle imaging with minimal distortion

The DSL184B-NIR-F2.0 is designed for professionals who require high-quality NIR imaging capabilities. Its tailored distortion feature ensures precise image capture across its entire field of view, and its lack of an IR cutoff filter allows for superior performance in NIR-sensitive applications. Whether you're working on night vision systems, machine vision, or industrial automation, this lens delivers the flexibility and performance needed to capture both visible and infrared light with clarity and precision.

For users looking for a durable, high-performance fisheye lens optimized for near-infrared imaging, the DSL184B-NIR-F2.0 provides a reliable solution that can withstand the rigors of demanding environments.
