Cylindrical lenses made of highly polished glass, magnifies in only one dimension. These lenses are used in transforming a point image to a line or changing the height of an image without changing its width.
Achromatic lenses are cemented with two lenses mainly used to reduced values of spherical aberration, coma, and chromatic aberration. Sunday offer positive achromatic lenses and negative achromatic lens with coatings
Structure doublet lenses
Material Optical glass, UVFS,Germanium, Silicon,CaF2,MgF2,ZnSe ZnS,Sapphire
Diameters Available 0.1mm to 600mm D: Customer Design.
We employ some experienced engineers and technical personnel from chang chun institute of optics, fine mechanics and physics, which is part of the chinese academy of science. The number of workers has more than fifty people in our factory. According to your request we will try our best work for your company. Our fªstandardfª product line includes cylindrical lenses, lenses, plano-convex cylindrical lenses, plano-concave cylindrical lenses, spherical lenses, aspheric lenses, prism, filter, achromatic lenses and reflector etc.
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.
