The convex surface of aspheric plano-convex lens is aspheric, with small spherical aberration and short focal length. It is often used to converge illumination light or collimate point light source. The application band is wide, from visible light to infrared region with 1500m wavelength. Using special grinding equipment for processing, there are no defects such as material shrinkage, cracks and notches caused by die-casting lenses.
