Plano-concave lenses are useful for a wide range of applications. These lenses are manufactured from BK7A grade A (or customer design) optical glass and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens, simply append the wavelength in nanometers to the product number.
A-STAR photonics 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.
