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.
