M5.5 Wide Angle Lens Applications

Core Application Scenes

The primary advantage of this 1.6mm lens is its very wide field of view. With a 105° horizontal FOV, the lens can capture a broad scene even when the available camera-to-object distance is limited.

Unlike a low-distortion wide-angle lens, this design has a specified distortion below -16%, so it should be selected when wide scene coverage is more important than maintaining straight-line geometry.

Typical applications include:

• Ultra-wide embedded imaging
• Compact vision modules
• Wide-area object detection
• Short-distance monitoring
• Compact robotic vision modules
• Embedded industrial cameras
• Space-constrained inspection equipment
• Wide-angle sensing and imaging systems

For applications where image geometry is critical, engineers should evaluate the effect of the specified distortion during system design. TOWIN’s Distortion Guide provides useful background when comparing wide-angle and low-distortion optical designs.

Designed for ultra-wide-angle embedded imaging applications requiring maximum scene coverage from a compact optical module.

Compatible Devices

The M5.5X0.35 mount makes this lens particularly relevant to miniature camera modules where conventional M12, C-mount, or CS-mount lenses may be too large.

Potential compatible device configurations include:

• 1/4″ compact camera modules
• Miniature embedded cameras
• Small industrial vision modules
• Compact robotic cameras
• Embedded monitoring devices
• OEM optical modules
• Space-constrained imaging assemblies

Before integration, the sensor size and optical image coverage should be verified. The specified image format is 1/4″, while the actual field of view depends on the sensor dimensions used with the lens.

Engineers can use TOWIN’s Sensor Guide to understand the relationship between sensor format and lens selection.

Ultra-Wide Field of View

The 1.6mm focal length provides a 120° diagonal FOV, together with 105° horizontal and 83° vertical coverage. This makes the lens suitable for applications where the camera needs to see a large area without moving farther away from the target.

For example, when the available installation space is restricted, a shorter focal length can help increase scene coverage. However, the resulting optical distortion should be considered when the application involves dimensional measurement or geometric analysis.

The FOV Calculator can help engineers evaluate field-of-view requirements when selecting a lens for a specific camera and installation geometry.

Distortion Characteristics

The specified distortion is <-16%, which is significantly different from a low-distortion machine vision lens. This characteristic is consistent with an ultra-wide-angle optical design where maximizing field coverage is a higher priority than maintaining straight-line geometry.

This lens is therefore better suited to applications such as broad-area viewing, detection, monitoring, and embedded perception than precision measurement tasks where very low distortion is required.

For applications requiring controlled geometric accuracy, engineers should consider TOWIN’s Low Distortion Lens category instead.

Compact Optical Integration

The M5.5X0.35 mount, 0.8mm B.F.L., and compact 6P construction are important specifications for miniature optical integration.

Mechanical designers should verify:

• Mount compatibility
• Sensor position
• Back focal distance
• Housing clearance
• Optical alignment
• Available installation space

Lens Selection Considerations

When selecting this 1.6mm ultra-wide-angle lens, engineers should evaluate the following parameters together:

1. Image Format: The specified image size is 1/4″.
2. Focal Length: 1.6mm provides an extremely wide viewing angle.
3. Field of View: 120° diagonal, 105° horizontal, and 83° vertical.
4. Distortion: <-16%, which should be considered when image geometry matters.
5. Aperture: Fixed F2.4 aperture.
6. Working Distance: 0.1m M.O.D. for close-range imaging configurations.
7. Mount: M5.5X0.35 for miniature optical assemblies.
8. Focus: Manual focus for optical adjustment during integration.

TOWIN’s Lens Selection Guide can help engineers compare focal length, sensor format, field of view, distortion, and mechanical requirements before choosing a lens.

Frequently Asked Questions

Q1: What is the field of view of this 1.6mm lens?

A: The lens provides a 120° diagonal field of view, 105° horizontal field of view, and 83° vertical field of view based on the specified optical configuration.

Q2: Is this lens a low distortion lens?

A: No. The specified distortion is <-16%. This lens is designed primarily for very wide scene coverage rather than low-distortion imaging.

Q3: Is the 1.6mm lens suitable for wide-angle imaging?

A: Yes. Its 120° diagonal FOV and 105° horizontal FOV make it suitable for applications requiring very broad image coverage from a compact camera position.

Q4: What sensor size is this lens designed for?

A: The specified image size is 1/4″. The actual camera sensor should be checked for compatibility before system integration.

Q5: What is the minimum object distance?

A: The specified M.O.D. is 0.1m, or 100mm, making the lens suitable for relatively close-range imaging configurations.

Q6: What mount does this lens use?

A: The lens uses an M5.5X0.35 mount, which is intended for miniature camera and embedded optical assemblies.

Q7: Is this lens suitable for precision measurement?

A: The specified distortion is <-16%, so the lens is generally better suited to wide-area viewing, detection, and embedded imaging than precision measurement applications requiring very low geometric distortion.

Q8: What is the difference between this lens and a low-distortion wide-angle lens?

A: This 1.6mm lens prioritizes an extremely wide field of view, reaching 120° diagonally, while a low-distortion lens prioritizes maintaining image geometry. The appropriate choice depends on whether scene coverage or geometric accuracy is the main system requirement.
