Optical Lenses Manufacturer | Custom Precision Optical Components
Chenyu Optics is a custom optical lenses manufacturer supplying precision lenses for global B2B customers. Our manufacturing capability covers spherical lenses, aspheric lenses, cylindrical lenses and achromatic lenses using optical glass, fused silica and infrared materials. Custom designs are available with precision polishing, coating and inspection according to customer drawings.
Optical Lenses Overview
Optical lenses are curved optical components designed to focus, collimate or diverge light for imaging, illumination and beam-shaping applications. As a custom optical lenses manufacturer, Chenyu Optics produces spherical and aspheric lens geometries to meet specific focal length, aperture, surface quality and coating requirements.
Lens range includes plano convex, plano concave, double convex, double concave, aspheric, achromatic, cylindrical and infrared lenses, manufactured from optical glass, fused silica and infrared materials such as ZnSe, ZnS, germanium and silicon, supporting applications across the visible, UV, NIR and IR ranges.
Chenyu Optics manufactures each optical lens to customer drawings, with in-house precision polishing, CNC grinding, optical coating and dimensional inspection supporting projects from prototype quantities through OEM production volume.
