Negative Achromatic Doublets
Product Details
are used to minimize or eliminate chromatic aberration. The achromatic design also helpstominimize spherical aberrations. Achromatic Lenses are suitablefor a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An , which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes thansingle lenses.Opticreateprovides achromaticnegativebonding lenses with anti-reflection coating(suitable for ultraviolet, visible or infrared light).
