Day / Night Vari-Focal Lenses
Aspherical Design, DC Auto Iris, IR Corrected Lens


Today's lens market is rapidly changing from part-time observation (day or night) to round-the-clock surveillance. Honeywell offers a real solution to day and night surveillance applications with its line-up of DC Vari-focal Auto Iris lenses. With Honeywell Day/Night Vari-focal technology, you now have the ability to upgrade or integrate video security systems affordably.

The Honeywell Day/Night Vari-focal lenses deliver clear, sharp, color images in daylight and black and white images in darkness using near infrared illumination, without the need to refocus the lens. Advanced aspherical design engineering reduces distortion and provides accurate visual identification of subjects. Honeywell’s lenses achieve day/night lighting corrections through a combination of proprietary optical design and aspherical elements, allowing superior wide aperture performance (F0.95) in low light to capture high quality images even in horizontalfield angles up to 94 degrees.

Market Opportunities
In addition to extraordinary low-light functionality, Honeywell Day/Night lenses are compact, lightweight and easy to install, making them perfect for use with True Day/Night cameras. The Honeywell Day/Night Vari-focal lenses are ideal in outdoor installations such as parking lots, ports, and other areas where low light imaging is important.


  • Ability to provide a high contrast, clear, and detailed picture of the subject in daylight, low light and near infrared light, allowing identification of a subject rather than just observation
  • Fastest maximum aperture of lens in class
  • Suitable for all daylight and near infrared night time surveillance applications
  • Compact, lightweight
  • Quick and accurate adjustment of image field of view and focus
