NIR I Coated Double-Convex (DCX) Lenses

AR Coated to Provide <0.5% Reflectance per Surface for 600 - 1050nm
Minimize Aberrations Including Spherical and Coma
UV Fused Silica DCX Lenses Available
Other Coating Options Available: Uncoated, MgF₂, VIS 0°, NIR II, VIS-EXT, VIS-NIR, and YAG-BBAR

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