1.9mm M5.5 Miniature Wide Angle Lens Applications

Ultra-Wide Embedded Vision

The 120° diagonal FOV and 95° horizontal FOV make this lens suitable when a camera needs to capture a large scene from a short working distance. The 1.9mm focal length helps reduce blind areas while maintaining a highly compact optical package.

Typical applications include:

• Compact industrial inspection cameras
• Embedded vision modules
• Small robotic vision devices
• Compact monitoring cameras
• Machine-mounted wide-area cameras
• Edge AI vision devices
• Indoor and equipment-area monitoring systems

Designed for compact embedded vision applications where wide scene coverage is required within a limited installation space.

5MP Industrial Imaging

With support for 5MP resolution, this lens can be integrated with compact 1/4″ image sensors for applications requiring both wide coverage and useful image detail. Its fixed focal length simplifies mechanical integration and eliminates the need for a focusing or zoom mechanism.

For system designers comparing sensor and lens compatibility, the Sensor Guide provides additional information about image sensor formats and lens matching.

Fisheye and Wide-Angle Imaging

The combination of 120° diagonal FOV, 95° horizontal FOV, and less than -12% TV distortion gives this lens a strong ultra-wide optical characteristic. It is appropriate when maximum scene coverage is more important than maintaining a rectilinear image.

Compact Machine Vision Integration

The M5.5×0.25 mount, 4.7mm T.T.L., and 0.7mm M.B.F.L. allow the lens to be installed into compact camera housings and embedded imaging systems where conventional C-Mount or CS-Mount lenses would be too large.

Frequently Asked Questions

Q: What sensor size is this 1.9mm lens designed for?
A: This lens is designed for 1/4″ image sensors and provides a 120° diagonal, 95° horizontal, and 75° vertical field of view.

Q: Is this 1.9mm lens a wide angle lens?
A: Yes. Its 120° diagonal FOV and TV distortion below -12% give it a strong ultra-wide optical characteristic. It is intended for applications where broad scene coverage is a priority.

Q: What resolution does this M5.5 lens support?
A: The lens is specified for 5MP resolution, making it suitable for compact high-resolution imaging systems using compatible 1/4″ sensors.

Q: What is the advantage of the 1.9mm focal length?
A: The short 1.9mm focal length provides a very wide field of view, allowing the camera to capture more of the surrounding scene from a relatively short installation distance.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.2 aperture, providing a fixed optical configuration suitable for compact embedded camera designs.

Q: What does the IRCF structure mean?
A: IRCF refers to an IR Cut Filter configuration. It helps manage infrared wavelengths in visible-light imaging systems. It should not be interpreted as an IR-corrected optical design.

Q: What makes this lens suitable for compact camera modules?
A: Its M5.5×0.25 mount, 4.7mm T.T.L., 0.7mm M.B.F.L., and 1.9mm focal length allow it to fit compact camera and embedded vision architectures where installation space is limited.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, allowing the lens to be used for relatively close-range wide-angle imaging.
