Aspheric lens group design, with ultra wide angle field of view: Aspheric lens surface is neither flat nor spherical, spherical aberration can effectively correct and other aberrations. Among them, the wide-angle lens astigmatism often occur can also be effectively controlled. Astigmatism is also an imaging defect, the subject is formed through the lens when the focus is not in a plane, due to high (from the center of the screen) different magnification caused by the focus is not real. Therefore, astigmatism can be corrected by gradually changing the refractive index from the center of the lens by using an aspherical lens.

It can be difficult for personnel to enter the environment to detect and monitor. Such as the observation of various kiln is burning material, explore the grass hidden objects. The lens has a good high temperature and corrosion resistance characteristics, good image quality, wide field of vision, small distortion. Widely used in iron and steel, metallurgy, power, cement, glass and glass tin bath and other industries high temperature monitoring.

In addition can be customized according to user needs a variety of industrial high temperature pinhole lens
