HIGHLIGHTS
Fujinon Lens Series for Day/Night Cameras
Day/Night cameras, which are becoming an integral part of the security market, depend on lenses that can transmit light in 700nm-1000nm range when used at night.
Standard lenses transmit light in the 400nm-700nm range, so when used in a 24-hour surveillance application results in a blurred or out of focus image. .
Refocusing Not Required for 24-Hour Continuous Surveillance
As a world leader in optical design we have created a Day/Night lens line that utilizes specialized lens elements making it possible for 24-hour continuous surveillance without the need for re-focusing. .
The lenses also maintain extremely low chromatic aberration that provides high quality images from visible light (day time) to near infrared (night time) applications. .
When a camera, which serves day and night, is used with a lens exclusively for daylight (visible rays), it accepts visible rays in the daytime and near infrared rays at night.
The two kinds of rays with different wavelengths form an image in focus at a different focal point, and product out of focus images unless it is adjusted in the evening or at dawn.
There is a growing need for compact, high quality lenses for 24/7 surveillance applications such as parking lots, factory premises, streets. Continuous surveillance is also required for public facilities such as airports, harbors and border patrol, requiring more versatile focal lengths and higher zoom ratios.
Fujinon has developed lenses that respond to infrared illumination to capture clear, corrected images, even at 0 lux. Fujinon offers a lineup of lenses from the standard focal length of 2.9-8mm, to the diverse focal length of 12.5-2200mm.
→ Advanced design engineering and special optic glass adopted, best suited for color, monochrome and day and night cameras
→ High accuracy aspheric lens adopted, achieving the high quality image
→ Built-in ND filter of T360, supporting super sensitive cameras
