λ/4 Achromats
from Newport MKS
The PAC10AR.15 Broadband Achromatic Lens is a 345 nm to 700 nm anti-reflection coated, 0.49 inch (12.5 mm) diameter, N-FK5 and N-F2 achromatic doublet lens with an effective focal length of 25.0 mm. This achromat is computer optimized to provide diffraction limited performance for polychromatic... [See More]

from CeNing Optics Co., Ltd.
Achromatic lenses are lenses consisting of two or more elements, which are usually made of crown and flint glass with differing indices of refraction. One element is positive, the other is negative. Distinct wavelengths can be corrected for chromatic aberration. Achromatic lenses are nearly free... [See More]

from Artifex Engineering
The achromatic lens consists of two or more elements, usually of crown and flint glass, such that the composite element has been corrected for chromatic aberration with respect to two selected wavelengths. In these lenses, chromatic, spherical and coma aberrations are considerably reduced. These... [See More]

from ECOPTIK (CHANGCHUN) LTD
A cemented cylindrical lens can minimize chromatic aberration, so it can be used to focus a single direction of a multi-color light beam. Unlike a spherical lens that produces a point focusing spot, a cylindrical lens can produce a linear focusing spot. Our cylindrical achromatic doublets are... [See More]
