Because of their specific construction, plano-convex lenses efficiently focus and collimate laser light. As one of the basic optical components used in the light focusing and collimating process, plano-convex lenses provide the foundation on which Shanghai Raysoar engineered the state-of-the-art laser technology and high quality optical components. Shanghai Raysoar specializes in engineering high quality optical materials, and strives to eliminate aberrations and increase lens quality. Astro-Optical has also incorporated engineering standards for specific wavelengths used in the laser focusing and collimating process. Having close interactions with laser technology engineering, Astro-Optical has expanded its service with laser technology components beyond the supply to lens installation, maintenance, and laser operation safety training. The trust and quality deliverance to the customer has been the foundation for high standards and reliability.
