Optical Lens Double Convex Lens DCX BK-7

About This Product
Double-convex lenses (DCX) have a positive focal length and are primarily used for image magnification and light focusing applications.
Biconvex lenses with double-sided convergence ratios are considered the most useful among single lenses for the purpose of forming conjugate images with magnifications within approximately 5x (or 1/5x). When the distance from a 1:1 conjugate ratio lens to the object and image is twice the focal length, coma, torsion, and lateral chromatic aberration are almost eliminated. At magnifications of 5x or more, infinity image formation occurs. Therefore, it is recommended to use a plano-convex lens.
■Material: BK-7
BK Group glass has been widely used for a long time because it has good light transmittance up to short wavelengths, has few bubbles, striae, and discoloration, and is hard and scratch-resistant. Among them, BK7 is a relatively hard glass that is scratch resistant, easy to handle, and does not require any special treatment when polishing. The bubbles and inclusions contained in BK7 are 0.029 mm2 per 100 cm2, and it has good transmittance for wavelengths above 350 nm.
