Aspheric Lens can correct various aberrations and improve imaging quality in optical systems. It can replace multiple spherical parts with one or several aspheric parts, thereby simplifying the instrument structure, reducing costs and effectively reducing the weight of the instrument. We can uses CNC polished aspheric lenses controlled by computers to achieve better surface flatness and focal length deviation.
Materials: Silicon, Germanium, Chalcogenide Glass, Zinc Selenide, Calcium Fluoride, Barium Fluoride, Arsenic Vum Aluminum, Acrylic, etc.

Optical lighting systems, stage lighting, and other applications are the primary uses for aspheric lenses, also known as condenser lenses. Our hot briquetting technique is imported from Japan, where it can produce large quantities of aspheric lenses with surface form errors of less than 100 microns.
