3.5-10mm IR Corrected Lens Applications

Core Application Scenes

The combination of a 3.5mm ultra-wide focal length and motorized zoom makes this lens suitable for imaging systems that need to cover a large scene while retaining the ability to narrow the viewing angle when required. On a 1/1.8″ sensor, the horizontal FOV ranges from 117° at 3.5mm to 42° at 10mm, allowing the same optical system to move from broad-area coverage to more focused observation.

The lens uses a fixed F2.0 aperture and motorized focus and zoom, making it suitable for systems where optical adjustments need to be controlled remotely rather than manually. The IR-corrected design is particularly useful for applications that operate across visible and near-infrared wavelengths, helping maintain more consistent focus when illumination changes between spectral ranges.

The specified distortion is intentionally optimized for an ultra-wide-angle design rather than geometric accuracy. At 3.5mm, the specified distortion is below -47% on a 1/2.5″ sensor, while distortion improves to below -6% at 10mm. Therefore, this lens is better suited to wide-scene coverage and situational imaging than precision measurement.

Designed for wide-area industrial imaging and remotely controlled vision applications where ultra-wide coverage, motorized zoom, and IR-corrected performance are required.

Wide-Area Industrial Monitoring
The 3.5mm setting provides up to 117° horizontal coverage on a 1/1.8″ sensor, making it suitable for monitoring large areas from a relatively compact camera position.

Smart Security & Situational Imaging
The motorized zoom allows users to change framing without physically accessing the camera, while the wide-angle starting point provides broad scene awareness.

Near-Infrared Vision
The IR-corrected optical design makes the lens suitable for systems using NIR illumination where maintaining consistent optical focus is important.

Compact Embedded Vision
The D14 mount and 7.5mm BFL support integration into compact camera assemblies where installation space is limited.

Frequently Asked Questions

Q: What is the focal-length range of this lens?
A: The lens provides a 3.5–10mm motorized zoom range, allowing the horizontal field of view to be adjusted according to the imaging requirement.

Q: What is the widest horizontal field of view?
A: On a 1/1.8″ sensor, the maximum horizontal FOV is 117° at 3.5mm. On a 1/2.5″ sensor, the maximum specified horizontal FOV is 90°.

Q: Is this lens suitable for wide-angle imaging?
A: Yes. The 3.5mm focal length provides a 117° horizontal FOV on a 1/1.8″ sensor, making wide-area imaging one of its primary applications.

Q: Does the lens support IR imaging?
A: Yes. The lens is specified as IR corrected, making it suitable for imaging systems that use visible and near-infrared illumination.

Q: Is the zoom manually or electronically controlled?
A: Both zoom and focus are specified as motorized, allowing optical adjustment through an integrated camera or control system.

Q: What is the distortion at the wide-angle end?
A: At 3.5mm on a 1/2.5″ sensor, the specified distortion is less than -47%. At 10mm, it improves to less than -6%. This means the lens should be selected for wide-area coverage rather than low-distortion measurement.

Q: What is the minimum object distance?
A: The specified M.O.D. is 0.3m, providing flexibility for relatively close-range wide-angle imaging.

Q: What camera format is compatible with this lens?
A: The lens is specified for a 1/1.8″ image format and also provides a separate FOV specification for 1/2.5″ sensors. Camera compatibility should therefore be checked against the required image circle and mechanical interface before integration.
