Product Family Description

  • Up to 1/1.8", S-Mount Lens
  • Up to 5 MegaPixels, 2.8µm Pixel Size Sensors
  • Liquid Lens Provides Quick Autofocus
  • 6mm to 16mm Focal Length

TECHSPEC® Liquid Lens M12 Lenses feature a high-resolution f/2.4 optical design with an integrated liquid lens, allowing for fast electronic focus, superior image performance, and a quick autofocus solution. When combined with appropriate camera and software, the focus tunable liquid lens provides the active focus control needed to achieve an autofocus solution. The high light throughput f/2.4 aperture is ideal for high-speed machine vision applications. TECHSPEC® Liquid Lens M12 Lenses incorporates a 2-piece housing design for easy access and replacement of the included liquid lens. The liquid lens can also be rotated 180° inside the imaging lens for quickly accessing the liquid lens control cable.

These lenses won the 2nd place 2019 Inspect Award.

Note: Driver and software are required for operation and must be purchased separately unless camera in use has liquid lens control capability. Various drivers and software are included in the Electronics Development Kit (#17-123). Individual drivers can also be purchased separately if software is not needed (#12-247 or #12-248).
