Positive Meniscus Lens, UV Fused Silica, Low Spherical Aberration Lens Overview: Positive meniscus (convex-concave) lenses are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration. When used to focus a collimated beam, the convex side of the lens should face the source to minimize

Negative Meniscus Lens, UV Fused Silica, Minimize Spherical Aberration Lens Overview: Negative meniscus (convex-concave) lens is designed to minimize spherical aberration in optical systems. When used in combination with another lens, a negative meniscus lens will increase the focal length and decrease the numerical aperture (NA) of the system without introducing significant spherical aberration. When used to diverge light, the convex surface should face the beam to minimize

Plano Convex (PCX) Spherical Lens, N-BK7, Focusing Light Overview: Plano-Convex (PCX) Lenses have a positive focal length, can focus a collimated beam or collimate light from a point source, making them ideal for collecting and focusing light in imaging applications. Star Optic provides Plano-Convex Lenses fabricated from RoHS-compliant N-BK7, UV fused silica, N-SF11, CaF2, Si, Ge, ZnSe and Sapphire. Our Plano-Convex Lenses are also used in applications involving emitters,

Positive Achromatic Lens, Spherical Aberration Lens Overview: An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a
