Ideal for Imaging Applications
Minimize Aberrations Including Spherical and Coma
UV Fused Silica DCX Lenses Available
Anti-Reflection Coating Options: MgF₂, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, and YAG-BBAR

TECHSPEC® Uncoated 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. TECHSPEC Uncoated Double-Convex Lenses are available in a variety of substrates and coating options for the visible and NIR spectra.
