Wide Angle Lens – CCL127027MP

CCL127027MP Low distortion wide angle 1/2.7″ 2.7mm 102° M9 mount lens with HD 2MP OV2710 UAV drone

2.7mm 2MP M9 850nm Filter Wide Angle Lens

This 2.7mm wide angle lens is designed for compact imaging systems that require a broad field of view, short optical length, and dedicated 850nm wavelength filtering. Featuring a 1/2.7″ image format, 2MP resolution, and up to 122° diagonal FOV, the lens provides wide-area image coverage for space-constrained camera modules. Its 2.7mm focal length delivers a 102° horizontal and 62° vertical field of view, while the fixed F2.4 aperture provides a practical optical configuration for embedded imaging devices. The 6-element optical design with an integrated 850nm filter makes this lens particularly suitable for imaging systems operating around the 850nm wavelength. With an M9×P0.35 mount, 9.95mm TTL, and 2.2mm B.F.L., this compact fixed focal lens is well suited to miniature camera assemblies. Designed for compact 850nm imaging, embedded vision, smart monitoring, and near-infrared camera applications, it provides a practical solution where both wide coverage and limited installation space are important.

M9 850nm Filter Wide Angle Lens Applications & Compatible Devices

850nm Imaging Systems

The integrated 850nm filter makes this lens suitable for camera systems specifically designed to capture or operate around the 850nm wavelength. The 2.7mm focal length and 102° horizontal FOV allow the camera to cover a broad scene while maintaining a compact optical structure.

Potential applications include:

• 850nm imaging modules
• Near-infrared camera systems
• IR illumination-based monitoring
• Embedded wavelength-specific cameras
• Compact sensing equipment

When designing an optical system around a specific wavelength, TOWIN’s Optical Design resources can help engineers evaluate the relationship between wavelength, optical performance, and lens configuration.

Compact Smart Monitoring

The 102° horizontal FOV provides extensive scene coverage from a small camera module. This makes the lens suitable for compact monitoring equipment where a wide viewing area is needed but the camera housing has limited installation space.

Compatible equipment can include:

• Compact security cameras
• Embedded monitoring modules
• Smart home cameras
• IoT imaging devices
• Indoor monitoring cameras
• Small-format vision modules

The wide field of view can reduce the need for multiple cameras in applications where broad scene coverage is a priority.

Embedded Vision & Small Camera Modules

With a 9.95mm TTL and M9×P0.35 mount, this lens is designed for applications where mechanical space is limited. Its 2.7mm focal length provides broad coverage while maintaining a miniature optical configuration.

It can be considered for:

• Embedded vision cameras
• Compact inspection modules
• Robotics sensor modules
• Smart devices with integrated cameras
• Portable imaging equipment
• Space-constrained camera assemblies

Wide-Area Imaging

The 122° diagonal FOV makes this lens appropriate for applications requiring a broad perspective from a relatively small camera. The 2MP resolution is suitable for monitoring and detection tasks where wide coverage is more important than very high pixel density.

Engineers can use TOWIN’s FOV Calculator to estimate the relationship between sensor size, focal length, and viewing angle when evaluating this type of wide angle lens.

Why Choose This 2.7mm Wide Angle Lens?

This lens combines a 2.7mm focal length, 122° diagonal FOV, 850nm filter, compact M9 mount, and short 9.95mm TTL into a miniature optical configuration. It is particularly suitable for engineers developing compact cameras that need wide-area coverage together with wavelength-specific optical filtering.

Unlike conventional visible-light wide angle lenses, this configuration incorporates an 850nm filter, making it a more application-specific solution for imaging systems designed around this wavelength.
