Talent training

Establish scientific and technological innovation joint laboratories and teaching practice cooperate with Changchun University of Science and Technology and Xi'an Technological University in order to cultivate optical talents.

Aspheric lens technology

The inside of the lens adopts a combination of aspherical lens and spherical lens. The use of aspherical lens can effectively correct various aberrations, greatly improve image quality, miniaturize the lens and obtain the most imaging effect.

Low dispersion glass material

Using low-dispersion materials, using its low refractive index characteristics to reduce the dispersion of the beam, which can effectively reduce the dispersion. It is effective in correcting axial chromatic aberration at the telephoto end and vertical chromatic aberration at the wide-angle end.

Temperature drift control

Using optical materials with low coefficient of thermal expansion, under different temperature environments, the lens does not need to be refocused, and a clear image can be obtained.

Flat image surface

The excellent optical design makes the image center to the edge uniformly achieve high pixels and high contrast, which can be better matched with high-definition network cameras.

Day and night confocal

The advanced optical design makes the visible light and near-infrared light imaging surfaces of the lens almost overlap, ensuring that the lens can clearly image both day and night.
