λ/4 Optical Lenses Datasheets

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]

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]

Ball Lens for Diode Lasers -- LMS-1.0-0.55-LSFN
from CVI Laser Optics

CVI Melles Griot spherical ball lenses are ideal for fiber-to-fiber and diode laser-to-fiber coupling. They are easier to align than thin lenses and have greater coupling efficiency. f-number values have been calculated for all spheres. A black dot, which indicates the optical axis, can be removed...
