λ/4 Achromats

Achromatic Lens
from Dayoptics, Inc.

A transparent optical component consisting of one or more pieces of optical glass with curved surfaces(usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object. Dayoptics provides these lenses with the material... [See More]

Cylinder Positive Achromatic Lenses
from Dayoptics, Inc.

Cylindrical lenses focus light in only one dimension and are most commonly used to correct astigmatics in the eye, and in rangefinders, to produce astigmatism, stretching a point of light into a line. Recently cylindrical lens has been widely used in semiconductor diode lasers as FAC lenses. [See More]

Achromatic Lenses
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]

Optical Lenses -- Achromatic Lenses for NIR
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]

Visible Achromatic Doublet Lenses
from Newport Corporation

Ouir Visible Achromatic Doublet Lenses feature minimized spherical aberration and coma at infinite conjugates, yielding minimal focus spot size. Unlike singlet lenses, achromatics have constant focal length independent of aperature and operating wavelength, and have superior off-axis performance. [See More]
