Edmund Optics® is a premier manufacturer of aspheric lenses. Our manufacturing
capabilities include polishing and molding in glass, plastic, and
a variety of crystalline substrates. Our state-of-the-art manufacturing capabilities
are supported by world-class metrology that includes Surface
Profilometry, and Aspheric Stitching Interferometry (ASI).
Whether you need just a few aspheric lenses for prototype, a few dozen for
pre-production, or a large volume for full production, Edmund Optics® wants
to ensure your project is successful.
COLOR-CORRECTED ASPHERIC LENSES
We offer several unique families of aspheric lenses, designed
to provide both spherical and chromatic aberration
correction. These families are ideal for applications requiring
near-diffraction limited focusing performance over a
range of wavelengths. Our color-corrected aspheric lenses
are fully supported by complete prescription data and drawings, available
for download on our website.
