Double-Convex Lens, also named Bi-Convex Lens, A Double-Convex Spherical Lens is compose of two convex surfaces, double-convex lens has a positive focal length. Double-convex Lens is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. Double-Convex Lenses are popular for many imaging applicationand used in beam expanders,projection optics systems, optical viewers etc.

Fused Silica is commonly used in applications from the Ultraviolet (UV) through the Near-Infrared (NIR) and its low index of refraction, low coefficient of thermal expansion, and low inclusion content make it ideal for laser applications and harsh environmental conditions.  UV Fused Silica Plano-Convex (PCX) Lenses feature industry leading diameter and centration specifications, making them ideal for integration into demanding imaging and targeting applications.
These uncoated lenses are ideal for a multitude of optics and photonics applications, as well as biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
