Achromatic Doublets
Customized Aspherical Lens
Product Details
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps to minimize spherical aberrations. Achromatic Lenses are suitable 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 single lenses. Opticreate provides achromatic positive bonding lenses with anti-reflection coating (suitable for ultraviolet, visible or infrared light).
