• Ideal for Imaging Applications
• Minimize Aberrations Including Spherical and Coma
• Variety of AR Coating Options Available
TECHSPEC® UV Fused Silica Double-Convex (DCX) Lenses, also referred to as bi-convex lenses, have two
positive, symmetrical faces with equal radii on both sides. These lenses are generally recommended for finite
imaging applications with a conjugate ratio (ratio between object distance and image distance) between 0,2 and
5. At a conjugate ratio of 1, aberrations such as spherical aberration, chromatic aberration, coma, and distortion
are minimized or cancelled due to the symmetric lens design.
