Shanghai Optics is one of the leading manufacturers from China that produce high precision Spherical lenses in plano-convex, double convex, and plano-concave shapes. Spherical lenses are key optical components can be categorized in two major type lenses, concave and convex lenses. While the convex lenses has positive focal that converging light to a focal point, the concave lenses has negative focal that used in applications that require beam divergence.
The most common materials that customers prefer to use are substrates include BK7, Fused Silica, N-SF11, Zinc Selenide, Calcium Fluoride, and Silicon etc. Using ZnSe, ZnS, BaF2, CaF2, MgF2 or Germanium Infrared materials, these custom Spherical lenses play critical roles in Infrared applications such as defense and security, environmental, medical and agriculture technologies.
These lenses can be made using Schott, Ohara, CDGM, Corning Fused Silica materials for visible wavelength. Customers are welcome to select variety of different materials that are used in UV, visible and IR wavelength for custom spherical lenses.
Custom BBAR coatings are available for different UV, visible, IR wavelengths upon request.
