5.2x Day And Night Vari-Focal Lens 2.7-13.5mm
The Fujinon YV5X2.7R4B 2 is a 1/3" Vari -Focal Day and Night using Aspherical lens. This lens has a 2.7-13.5mm focal length and F1.3 Iris Range.
The YV5X2.7R4B2 has wide aperture of F1.3, optimizing the performance at low lighting intensity. It is best suited for color, monochrome and day and night cameras.
→ Vari-Focal: Variable magnification lens with manually controllable angle. It functions as if you have multiple fixed focal lenses.
→ Wide Angle: Wide angle lens which ensures wide field of view.
→ Telephoto Long Focal: Telephoto lens with the ability to zoom.
→ Day & Night: Specially-designed lens supporting both visible light and near-infrared light to prevent out-of-focus of day & night cameras.
→ Manual Iris: Manually-operated iris.
→ CS Mount: Screw-in mounting commonly used in security lenses.
→ Metal Mount: Metal mounting with high accuracy and durability.
→ ND Filter: With the built-in ND filter, enables to optimize the brightness of the bright object in direct sunlight.
→ Aspherical Lens: Adopts the aspheric lens technologies developed in the most advanced lenses for broadcasting.
→ Wide Aperture Rate (F1.3): Lens with the wide aperature rate, optimizing the sensitivity of cameras.
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.
