IR Lens for OpenMV Cam 7 (2.8mm F2.0, M12 Mount)

₹669.00 (Inclusive of all taxes)
Out of Stock

This M12-mount IR lens enables your OpenMV Cam 7 to detect and track infrared light, as it lacks the standard 650nm IR cut filter. It provides a 115° wide-angle field of view for computer vision applications.

Features

  • Enables IR Light Detection – Removes the 650nm IR cut filter standard on OpenMV lenses, allowing the sensor to capture infrared wavelengths for specialized vision tasks.
  • Wide 115° Field of View – The 2.8mm focal length provides a broad viewing angle, ideal for tracking applications in robotics or interactive systems.
  • M12 x 0.5 Thread Mount – Standard industrial lens mount ensures a secure, precise fit onto the OpenMV Cam 7 and other compatible M12 camera modules.
  • Fast F2.0 Aperture – Allows more light to reach the sensor, improving performance in lower-light conditions for IR-based sensing.
  • Compact & Lightweight Design – Measures just 14x14x18mm and weighs 5g, making it suitable for space-constrained embedded vision projects.

Description

This specialized IR lens is engineered for the OpenMV Cam 7 platform, removing the optical barrier to infrared light detection. Unlike standard lenses that incorporate a 650nm IR cut filter to mimic human color perception, this lens permits a broader spectrum of light to reach the CMOS sensor. This enables developers to implement vision systems that track IR markers, perform eye-tracking via pupil reflection, or create interactive installations using IR light sources.

The lens features a 2.8mm focal length and a fast F2.0 aperture, providing a wide 115-degree horizontal field of view and improved light gathering. Its industrial M12 x 0.5 threaded mount ensures a stable, reliable connection to the camera module, maintaining focus alignment. The compact, all-metal barrel construction is designed for integration into finished products, drones, or robotic platforms where size and weight are critical factors.

Key Features

  • IR-Pass Optical Design – Specifically lacks an IR cut filter, allowing infrared wavelengths (typically 700nm+) to pass through to the image sensor.
  • Wide-Angle Vision for Tracking – The 2.8mm focal length and 115° FOV are optimal for tracking multiple IR points or objects within a scene.
  • Standard M12 Mount Compatibility – Threads directly onto OpenMV Cam 7 and other M12-mount camera boards (e.g., Raspberry Pi HQ Camera, many USB webcams).
  • Fast Aperture for Low-Light IR – The F2.0 aperture maximizes light intake, beneficial for passive IR sensing or active IR marker systems.
  • Compact Mechanical Design – Miniature form factor (14x14x18mm) and 5g weight enable integration into portable and aerial vision systems.
  • Direct Replacement for Stock Lens – Designed as a drop-in upgrade for the standard OpenMV Cam 7 lens to enable IR functionality.

Applications

  • Eye-Tracking & Gaze Detection Systems – Utilizes IR light reflected from pupils for human-computer interaction research or assistive technology.
  • IR Marker Tracking for Robotics – Enables robots or drones to follow passive IR reflectors or active IR beacons for navigation.
  • Interactive Art & Installations – Creates invisible IR light triggers for touchless interfaces or motion-activated displays.
  • Machine Vision with IR Illumination – Used in conjunction with IR LEDs for structured light, 3D scanning, or low-light inspection without visible light pollution.
  • Scientific Imaging – Captures infrared phenomena not visible to standard filtered lenses for educational or research purposes.

Frequently Asked Questions

How do I install this IR lens on my OpenMV Cam 7?

Power off your OpenMV Cam 7. Grip the stock lens barrel and unscrew it counterclockwise to remove it. Thread this IR lens clockwise onto the M12 mount until it is finger-tight. Avoid over-tightening. Power on the camera and adjust focus by slightly rotating the lens barrel while viewing a test image of a distant IR source or pattern. (44 words)

What is the main difference between this lens and the standard OpenMV lens?

The standard OpenMV Cam 7 lens includes a 650nm infrared cut filter that blocks light above this wavelength to produce color-accurate RGB images. This IR lens omits that filter, allowing both visible and infrared light (typically 700nm and above) to reach the sensor. This enables applications like tracking IR LEDs or using IR illumination for machine vision without visible light interference. (50 words)

Can this lens be used with other camera boards besides the OpenMV Cam 7?

Yes, this lens is compatible with any camera module featuring a standard M12 x 0.5 threaded lens mount. This includes many Raspberry Pi camera boards (with M12 adapters), industrial USB vision modules, and other embedded vision sensors. Verify your camera's mount specification before purchase. The 1/3" image format is suitable for sensors up to that size. (47 words)

What kind of projects is this IR lens best suited for?

This lens is ideal for projects requiring infrared light detection. Common uses include eye-tracking by reflecting IR off pupils, robotic navigation using IR beacons, interactive art with invisible IR triggers, and machine vision with IR illumination for low-light or glare-free inspection. It pairs well with active IR LEDs and the OpenMV IDE's built-in blob tracking functions. (48 words)
