Can I change the lens on my OV20i camera?

Yes, the lens can be changed. The OV20i uses a standard M12 lens mount, which allows you to swap lenses for different applications. The lens simply screws in and out of the camera.

Lens changing process:

  1. Power off the camera
  2. Unscrew the current lens by turning counter-clockwise
  3. Take Cover off after unscrewing
  4. Screw in the new lens by turning clockwise
  5. Power on and adjust focus in Imaging Setup
warning

Handle lenses carefully and avoid touching the glass surfaces.

Can I adjust the focus of the lens?​

Yes, you can adjust the focus. The OV20i includes a focus adjustment mechanism that allows you to optimize the image sharpness for your specific working distance and application.

How to adjust focus:

  1. Navigate to Imaging Setup in your recipe
  2. Use the Focus control slider or manual entry
  3. Adjust while viewing the live image until your target is sharp
  4. Save your imaging settings

What lens options are available?​

The OV20i uses M12 mount lenses. Available options include:

  • 6mm lens - Wider field of view, closer working distances
  • 8mm lens - Balanced view for general applications
  • 12mm lens - Standard option, good all-around performance
  • 16mm lens - Narrower field of view, longer working distances
  • 25mm lens - Telephoto option, detailed inspection of smaller areas

Where to get lenses:

  • Overview - Purchase directly from us for guaranteed compatibility
  • Third-party suppliers - Standard M12 lenses from other manufacturers
  • Local distributors - Many industrial suppliers carry M12 lenses

How do I know what lens I have?​

You can find your lens information from:

  • Physical lens marking - Focal length is usually printed on the lens barrel
  • Order documentation - Original purchase specifications
  • Measure field of view - Compare actual view to lens specification charts

What if I need a different field of view?​

Since the OV20i uses changeable M12 lenses, you have several options:

Immediate solutions:

  • Adjust working distance - Move camera closer or farther from target
  • Change mounting position - Reposition camera angle if possible

Lens change options:

  • Purchase different focal length - Choose from 6mm to 25mm options
  • Swap lenses easily - Simple screw-in/screw-out process
  • Try before buying - Test different focal lengths for your application

Contact Overview or your distributor for lens recommendations based on your specific application needs.

Can I clean the lens?​

Clean the protective cover, not the lens directly. The OV20i has a protective cover over the lens and LEDs that should be cleaned instead of the actual lens.

To clean the protective cover:

  • Use a clean, lint-free cloth
  • Use mild cleaning solution if needed
  • Clean gently to avoid scratches
  • The cover protects the lens from dust and contamination
note

The lens itself should remain protected under the cover and typically doesn't need direct cleaning.

What affects lens performance?​

Several factors impact lens performance:

  • Working distance - Distance from camera to target
  • Lighting conditions - Proper illumination is essential
  • Vibration - Secure mounting reduces image blur
  • Temperature - Extreme temperatures can affect focus
  • Cleanliness - Keep lens surface clean for best image quality
