China Gold Supplier for Optical Bk7 Glass Hemisphere Dome Lenses - double convex lens – DG
China Gold Supplier for Optical Bk7 Glass Hemisphere Dome Lenses - double convex lens – DG Detail:
Bi-Convex Lenses are the best choice where the object and image are at equal or near equal distance from the lens. When the object and image distance are equal (1:1 magnification), not only is spherical aberration minimized, but also coma, distortion, and chromatic aberration are identically canceled due to the symmetry. Bi-convex lenses function similarly to plano-convex lenses in that they have a positive focal length, and focus parallel rays of light to a point. Both surfaces are spherical and have the same radius of curvature, thereby minimizing spherical aberration. As a guideline, bi-convex lenses perform within minimum aberration at conjugate ratios between 5:1 and 1:5. Outside this magnification range, plano-convex lenses are usually more suitable.
Material for choices :
BK7, fused silica&quartz, and others demanded.
