Advantages and characteristics of lens:
1. 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.
2. Flat Image
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.
3. Multi Coating
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.
4. High resolution lens
The pixels of high resolution lenses are beyond 12.0 Megapixel, IR Cut and Lens Holder are available as per request.

1. Glass-plastic mixed lenses: the lens interior mostly uses glass lenses, plastic aspheric lenses mixed form, effective correction of aberration;

2. Low-dispersion glass materials: low-dispersion materials are used to effectively reduce dispersion. The effect of correcting the axial chromatic aberration at telephoto end and the vertical chromatic aberration at wide angle end is particularly significant.

3. Temperature drift control: Using optical materials with low thermal expansion coefficient, the lens can obtain clear pictures without re-focusing under different temperature environments.

4. Flatness of image surface: Excellent optical design technology is used to achieve high pixel and high contrast uniformly from the center to the periphery of the image.

5. Day-night confocal: Both visible and near-infrared light have almost no change in the focal plane, so that the image can get a clear effect in day and night.
