Advantages and characteristics of lens
Day & Night
With special design, IR series lenses make the portrait aberration
lowest, and the focal planes for the visible and infrared light
ranges almost the same, which means that the surveillance camera
can deliver sharp images in both day and night applications.
With the use of advanced optical design technology, our lenses can
get high definition and high contrast performance over the entire
image field, from the center to the periphery. Also, these lenses
are the most suitable for the image cut-out function of IP cameras.
To minimize double image and flare present in backlight, multi
coating is adhered to the lens surface. Hence, the lenses can show
high contrast resolution performance even in backlight.
High resolution lens
The pixels of Forecam high resolution lenses are beyond 3.0
Camera lens is the key to affect the image quality, if poor lens
quality, naturally difficult to capture a clear picture. "Optical
lens should meet clear imaging, light transmittance strong, evenly
distributed illumination image plane, a small image distortion,
adjustable aperture and other requirements.
