DSL183B-NIR-F2.2: Miniature Tailored Distortion Fisheye Lens without IR Cutoff Filter
The DSL183B-NIR-F2.2 is a miniature fisheye lens designed for near-infrared (NIR) imaging applications. With an effective focal length (EFL) of 1.32mm and an F/2.2 aperture, this lens is optimized for capturing wide-angle images in low-light conditions. Its tailored distortion profile ensures that images are sharp and clear, with minimal distortion across its 180-degree field of view. The absence of an IR cutoff filter allows the lens to capture both visible and infrared light, making it ideal for applications that require NIR sensitivity, such as security systems, night vision, and robotics.
Constructed with a durable metal barrel and M12x0.5 threading, the DSL183B-NIR-F2.2 is built for industrial and outdoor use. It is designed to withstand harsh environmental conditions while maintaining excellent optical performance, making it a reliable choice for professionals in demanding fields.
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: 4.9mm
- No IR Cutoff Filter (for NIR imaging)
- Metal barrel with M12x0.5 threading
- Tailored distortion for enhanced image clarity
Because the DSL183B-NIR-F2.2 lacks an IR cutoff filter, it is optimized for applications where infrared light detection is required, such as night vision systems and NIR-based machine vision. The lens’s wide field of view and tailored distortion profile ensure that it delivers accurate and detailed images, even in low-light or nighttime environments. It is also compatible with the CMT168 adapter, making it easy to integrate into a variety of imaging systems.
The DSL183B-NIR-F2.2 is an excellent choice for engineers and system integrators who need a miniature fisheye lens for NIR imaging. Whether you’re working on security systems, robotics, or industrial automation, this lens ensures high-quality performance with the flexibility to handle both visible and infrared light.
