Product Overview

Sunex M12 Fixed Focal Lens, EFL 1.7mm: A similar lens with an EFL of 1.7mm but without an IR cut-off filter, making it suitable for full-spectrum imaging, capturing natural light and near-infrared details.

The DSL209A-NIR-F2.0 is a wide-angle glass lens designed for 1/4" sensors, with an effective focal length of 1.7 mm and an F/2.0 aperture. Lacking an IR cut-off filter, it is ideal for applications where infrared sensitivity is needed, such as night vision or low-light imaging. Its M12x0.5 mount ensures compatibility with a range of devices, and distortion dewarping software is available to enhance image quality. Suitable for imaging tasks requiring high field-of-view and minimal distortion.
