Product Description
Optical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a point, while a Plano-Concave or Double-Concave lens diverges the light which traveling through the lens. Achromatic Lenses are ideal for correcting color, aspheric lenses are designed to correct spherical aberration.Ge, Si, or ZnSe lenses are suited for transmitting the Infrared (IR) spectrum, fused silica is well suited for the Ultraviolet (UV).
Plano-Concave (PCV) lenses
Plano-Concave (PCV) lenses have one flat and one inward curved surface. PCV lenses have a negative focal length and are used for image reduction or to spread light.
