Optical Lenses are high-precision optical components designed to focus or diverge light, widely applied in fields ranging from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a specific point, while a Plano-Concave or Double-Concave lens diverges light traveling through it. Achromatic Lenses are ideal for correcting color, and aspheric lenses are designed to correct spherical aberration. Ge, Si, or ZnSe lenses are specialized for transmitting the Infrared (IR) spectrum, while fused silica is perfectly suited for the Ultraviolet (UV) range.
Double-Convex Lenses
Double-Convex Lenses are essential in image relay applications or for imaging objects at close conjugates. These lenses feature positive focal lengths and two convex surfaces with equal radii. While aberrations may increase as conjugate ratios rise, DCX Lenses remain a versatile choice across numerous industrial and scientific applications.
