Plano convex lenses are designed to focus and collimate the light in optical system. The lenses are often used for laser, fiber, medical, sensor, communication and surveying instruments. Plano convex lenses are offered with different diameters ranging from 1.5mm to 800mm, and with different focal lengths. Anti-reflective coatings are applied to the lenses with different wavelengths, which will improve optical transmission greatly. We produce plano convex lenses with optical flint glasses, crown glass and infrared glasses, such as N-BK7, N-LaSF9, UV fused silica glass, silicon, germanium and sapphire glasses.
A-star Optics specializes in the development, production, and sales of optical products made of any material including BK7,quartz,sapphire etc. The product line covers thousands of categories, such as Dove Prisms, Filters, Rod Lenses, and sapphire watch Windows. Applications include defense and security, aerospace, optical ball covers for underwater cameras, automotive, medical, entertainment and design lighting, electronics and optoelectronics, laser technology, energy and utilities, universities and research, imaging lenses, microscopic inspection, and other industries. Many products and technologies have obtained national patents and software Copyrights, and have been approved by ISO9001 certificate.
