Cylindrical Achromatic Doublets
Description
Cylindrical Achromatic Doublets
Photonchina manufactures cylindrical achromatic doublets in both wavelength of visible and NIR. Our lenses are typically used to focus polychromatic light in one direction only while minimizing chromatic aberration. They create a line focus instead of a point focus, as seen in spherical lenses.
Our cylindrical lenses are desirable for various experimental setups, including beam shaping, laser projection, holography etc. Cylindrical doublets drastically reduce chromatic aberrations and can create a diffraction limited focus in one direction when used with monochromatic light.
Material: N-BK7/H-K9L，N-SF11 etc.
Optical coating: AR coating: 350-700nm; 650-1050nm
