Double convex lenses ( or Biconvex Lens) consist of two convex surfaces with a positive focal length, which can focus light into a point with a positive focal length. They are often used in imaging relay systems and imaging of objects at a finite conjugate distance or focusing, collimating, and expanding light beams.

AOS provides double-convex lenses without coating or anti-reflection coating to meet your different applications in various bands. Anti-reflection coating includes UV, VIS, NIR, and SWIR, which are double-sided coatings that can greatly reduce light reflection on the surface of the component and increase the transmittance of the double-convex lens.

AOS Optics provides double convex lens of a variety of materials. Among them, H-K9L optical glass substrates are suitable for visible light and near-infrared band applications, germanium, silicon, zinc selenide, calcium fluoride and other substrates are suitable for infrared band applications, and fused silica is suitable for Used in UV band applications.

Double convex lenses are commonly used in optical instruments such as telescopes, microscopes, collimators, and thermal infrared imagers. They are also widely used in security, automobiles, digital cameras, laser cutting and other fields, such as cameras, security cameras, laser printers, and sensors in consumer electronics. Biconvex lenses are also used in the fields of medical care, health care and environmental protection.
