Product Summary

Hybrid lens for 1/1.7″ sensors, featuring a 4.1 mm focal length and no IR-cut filter for optimal performance in NIR-sensitive imaging applications.

DSL186A-NIR-F1.8: Hybrid Lens for 1/1.7" Sensors Without IR Cutoff Filter

The DSL186A-NIR-F1.8 is a high-quality hybrid lens specifically designed for near-infrared (NIR) imaging applications. With an effective focal length (EFL) of 4.1mm and a wide F/1.8 aperture, this lens excels in capturing clear, high-quality images in low-light and night-time conditions. The absence of an IR cutoff filter allows the lens to capture both visible and infrared light, making it ideal for systems that rely on NIR imaging, such as surveillance, machine vision, and industrial automation.

This lens is optimized for HDR (high dynamic range) imaging, ensuring excellent performance in challenging lighting environments. The durable aluminum barrel with M14x0.5 threading ensures that the lens can withstand harsh industrial conditions while delivering reliable and consistent performance. The DSL186A-NIR-F1.8 is well-suited for NIR-based systems that require flexible day and night imaging capabilities.

Technical Specifications:

  • Effective Focal Length (EFL): 4.1mm
  • Aperture: F/1.8
  • Sensor Compatibility: Up to 1/1.7 inch
  • Image Circle: 8.85mm
  • No IR Cutoff Filter (optimized for NIR imaging)
  • HDR optimized for high dynamic range imaging
  • Durable aluminum barrel with M14x0.5 threading

The DSL186A-NIR-F1.8 is designed for professionals who require high-performance NIR imaging. Its ability to capture both visible and infrared light, combined with its wide F/1.8 aperture, makes it a versatile lens for low-light environments. Whether you're working on night vision systems, industrial automation, or machine vision, this lens provides the flexibility and performance needed to capture sharp, clear images across different spectrums.

With its robust construction and advanced optical design, the DSL186A-NIR-F1.8 ensures long-term reliability and excellent image quality, making it an excellent choice for NIR-sensitive applications that require consistent performance in challenging environments.
