1.6mm Low Distortion Miniature Lens Applications

Core Application Scenes

This lens is designed for applications where the camera module must remain extremely compact while still providing broad image coverage. Its 1.6mm focal length provides an 88° diagonal FOV on the specified 1/6″ sensor, while the <1% distortion specification helps maintain controlled image geometry.

Designed for miniature embedded vision application.

Typical applications include:

• Miniature Machine Vision: Suitable for compact inspection systems where optical installation space is severely limited.
• Embedded Vision: The short 2.3mm TTL supports integration into small camera modules and embedded imaging devices.
• Compact Inspection Cameras: Suitable for 1920 × 1080 inspection systems that require broad scene coverage within a small optical package.
• Robotics Vision: The 88° diagonal FOV can provide useful environmental coverage for compact robotic camera modules.
• AI Vision Modules: Suitable for embedded AI cameras requiring 2MP image capture and controlled optical distortion.
• Industrial Monitoring: Can be integrated into compact monitoring equipment installed in restricted spaces.
• OEM Camera Development: The Φ3.34mm mount and compact holder allow integration into customized miniature imaging assemblies.

For sensor and lens compatibility, the Sensor Guide provides useful information when designing a compact camera module.

1.6mm Optical Design for Compact Imaging

The 1.6mm focal length provides broad image coverage within a very small optical package. On the specified 1/6″ sensor, the lens delivers:

• 88° diagonal FOV
• 80° horizontal FOV
• 50° vertical FOV

This makes the lens suitable for applications where a relatively broad scene must be captured from a small camera module.

Despite the short focal length, the lens maintains less than 1% TV distortion, making it different from a conventional fisheye design. The controlled distortion can be beneficial for applications involving object recognition, positioning, inspection, or image analysis.

For estimating field of view based on sensor size and working distance, the FOV Calculator can help during the lens selection process.

Ultra-Compact Mechanical Package

The optical design is optimized for applications where camera dimensions are tightly constrained.

The lens features:

• 2.3mm total track length
• Φ3.34mm mount
• 6.3 × 3.9mm holder
• 1.6mm focal length

This compact configuration allows the lens to be integrated into camera modules that cannot accommodate conventional M12 or larger industrial lens assemblies.

The F2.0 aperture also provides a practical light-gathering configuration for miniature camera systems.

Low Distortion Imaging

Short focal lengths often require strong optical projection to achieve broad fields of view. This can result in significant barrel distortion.

This lens specifies <1% TV distortion, providing a relatively controlled image geometry for its compact optical format.

Potential applications include:

• Machine vision inspection
• Embedded object recognition
• AI image processing
• Robotic perception
• Industrial monitoring
• Compact visual inspection
• OEM imaging systems

2MP Full HD Sensor Compatibility

The lens is specified for a 1/6″ 1920 × 1080 sensor with 1.4μm × 1.4μm pixel size.

This makes it suitable for compact Full HD camera modules where physical size is a major design consideration.

The 2MP resolution provides sufficient image detail for many embedded inspection, recognition, monitoring, and machine vision applications without requiring the larger optical package often associated with higher-resolution industrial cameras.

The specified C.R.A. of <34.9° and R.I. >25% should also be considered when matching the lens to the selected miniature image sensor.

For detailed optical matching considerations, refer to TOWIN’s Optical Design resources.

Frequently Asked Questions

Q: What sensor is this 1.6mm lens designed for?
A: The lens is specified for a 1/6″ sensor with 1920 × 1080 resolution and 1.4μm × 1.4μm pixel size.

Q: What is the field of view of this lens?
A: On the specified 1/6″ sensor, the lens provides 88° diagonal, 80° horizontal, and 50° vertical FOV.

Q: Is this a fisheye lens?
A: No. Although the lens provides a relatively broad 88° diagonal FOV, its TV distortion is specified at less than 1%, so it is better classified as a low-distortion fixed focal lens rather than a fisheye lens.

Q: What is the resolution of this lens?
A: The lens is specified at 2MP and is designed for 1920 × 1080 imaging systems.

Q: What is the advantage of the 2.3mm TTL?
A: The 2.3mm total track length supports integration into extremely compact camera modules where conventional optical assemblies may not fit.

Q: What does the Φ3.34mm mount indicate?
A: It indicates a compact 3.34mm mechanical mounting diameter. It is not an M12, M9, or M8 threaded mount, so compatibility should be confirmed with the camera housing or module design.

Q: What does the 4P + IRCF construction mean?
A: The lens uses four plastic optical elements together with an infrared cut filter configuration. The IRCF helps control infrared wavelengths for the intended imaging system.

Q: Why are the CRA and pixel size important?
A: The chief ray angle and pixel size are important when matching a miniature lens to a small image sensor. Proper optical matching can help maintain illumination and image quality across the sensor.
