SF5 Glass Optical Lenses
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]

What is the application of Achromatic Lenses?. 1. Microscopes: a typical application of a good quality microscope objective is an achromatic lens, which provides a clear and no chromatic aberration image, which is essential for observing and studying the microscopic world. 2. Photographic lenses: in... [See More]

from CeNing Optics Co., Ltd.
A Powell lens is used to generate a straight line with aspherical curvature on its apex, thereby outputting a line that has an even distribution of energy. For comparison, cylindrical lenses generate Gaussian beam profiles with hot-spot center points and fading edges. The uniformity of the output... [See More]

from Edmund Optics Inc.
Designed and Manufactured by Edmund Optics. Prescription Information Available. As optical systems are pushed to be better, faster, and cheaper, it becomes necessary to explore aspheric solutions. Aspheric surfaces can increase the numerical aperture of a lens while minimizing system aberrations. [See More]

from Foctek Photonics, 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. Foctek provides these lenses with the material... [See More]
