Product Summary

Sunex M12 Fixed Focal Lens, EFL 1.389mm: A fixed focal lens with an EFL of 1.389mm, F2 aperture, supporting 0.3 Megapixels, suitable for an image circle of 4.8mm. Includes an IR cut-off filter at 650nm.

DSL184A-NIR-F2.0: Miniature Tailored Distortion Fisheye Lens Without IR Cutoff Filter

The DSL184A-NIR-F2.0 is a miniature fisheye lens optimized for near-infrared (NIR) imaging, making it an ideal choice for applications such as night vision, robotics, and surveillance systems that require NIR sensitivity. The lens offers an effective focal length (EFL) of 1.39mm and features a wide F/2.0 aperture, ensuring excellent low-light performance and allowing the capture of clear images in dark environments. The absence of an IR cutoff filter allows for greater flexibility when capturing both visible and infrared light, making this lens particularly useful for NIR-based systems.

This lens is tailored to minimize image distortion, providing a wide 180-degree field of view without sacrificing image quality. With its rugged design, including a metal barrel and M12x0.5 threading, the DSL184A-NIR-F2.0 is engineered for use in harsh industrial environments, making it a reliable and durable option for demanding applications.

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 DSL184A-NIR-F2.0 is designed to deliver exceptional image quality in both visible and infrared spectrums, providing unmatched versatility for NIR-sensitive applications. Its tailored distortion feature ensures precise image capture across the entire field of view, making it a perfect fit for use in security systems, machine vision, and other industrial applications that require NIR imaging. The lens is also compatible with the CMT821 adapter, allowing for easy integration into existing camera systems.

For professionals looking for a high-performance fisheye lens capable of delivering clear, accurate images in low-light and infrared-sensitive environments, the DSL184A-NIR-F2.0 offers an optimal solution. With its rugged construction and advanced optical features, this lens ensures reliability and performance even in the most challenging environments.
