New Kowa 1.1" 12MP lens series optimised for Sony sensors

5 Sep 2018

The new FC series of 1.1" C-Mount lenses from Kowa has been designed for use with 12 megapixel sensors with an image circle up to 17.6 mm. They are optimised to prevent unwanted shading on the new Sony IMX253 and IMX304 CMOS sensors by matching with the micro lenses on the sensors’ 3.45 µm pixels.

The lenses are initially available in 4 focal lengths between 8.5mm and 35 mm. They feature a wide-band coating which effectively decreases flare and ghosting and produces a high transmission from the visible to the NIR wavelength.

The following optical characteristics make the lenses suitable for a wide variety of factory automation and machine vision applications:

  • Sensor size: up to 1.1"
  • Focal length: 8.5 mm, 16 mm, 25 mm, 35 mm
  • Aperture: F1.8 - 2.5
  • MOD: 100 mm-200 mm

The compact FC range has dimensions ranging from 43 mm x 65.7 mm to 64 mm x 73.3 mm and can operate at temperatures from -10˚C to +50˚C. The robust construction includes a metal housing, metal mount and locking screws for both aperture and focus. This rugged construction make the lenses suitable for use in a wide range of industrial environments including those where space is restricted.
